When IKE is not used to establish security associations, a single transform set must be used. The transform set is not negotiated. Before a transform set can be included in a crypto map entry it must be defined using this command. A transform set specifies one or two IPSec security protocols either Encapsulation Security Protocol or Authentication Header or both and specifies which algorithms to use with the selected security protocol.
To define a transform set, you specify one to three "transforms"—each transform represents an IPSec security protocol ESP or AH plus the algorithm you want to use. When the particular transform set is used during negotiations for IPSec security associations, the entire transform set the combination of protocols, algorithms, and other settings must match a transform set at the remote peer.
The parser will prevent you from entering invalid combinations; for example, once you specify an AH transform it will not allow you to specify another AH transform for the current transform set. ESP provides packet encryption and optional data authentication and anti-replay services.
AH is embedded in the protected data; it inserts an AH header immediately after the outer IP header and before the inner IP datagram or payload. Traffic that originates and terminates at the IPSec peers can be sent in either tunnel or transport mode; all other traffic is sent in tunnel mode. For more information about modes, see the mode IPSec command description. The following tips may help you select transforms that are appropriate for your situation:.
Some consider the benefits of outer IP header data integrity to be debatable. After you issue the crypto ipsec transform-set command, you are put into the crypto transform configuration mode. While in this mode, you can change the mode to tunnel or transport. These are optional changes. After you have made these changes, type exit to return to global configuration mode. If one or more transforms are specified in the crypto ipsec transform-set command for an existing transform set, the specified transforms will replace the existing transforms for that transform set.
If you change a transform set definition, the change is only applied to crypto map entries that reference the transform set. The following example defines two transform sets. The second transform set will be used with an IPSec peer that only supports the older transforms. To create or modify a crypto map entry and enter the crypto map configuration mode, use the crypto map global configuration command. To delete a crypto map entry or set, use the no form of this command.
Note Issue the crypto map map-name seq-num command without a keyword to modify an existing crypto map entry. The name that identifies the crypto map set. This is the name assigned when the crypto map was created. The number you assign to the crypto map entry. See additional explanation for using this argument in the "Usage Guidelines" section. Indicates that Internet Key Exchange will not be used to establish the IP Security security associations for protecting the traffic specified by this crypto map entry.
Indicates that IKE will be used to establish the IPSec security associations for protecting the traffic specified by this crypto map entry. Optional Specifies that this crypto map entry is to reference a preexisting dynamic crypto map.
Dynamic crypto maps are policy templates used in processing negotiation requests from a peer IPSec device. If you use this keyword, none of the crypto map configuration commands will be available. Optional Specifies the name of the dynamic crypto map set that should be used as the policy template.
Using this command puts you into crypto map configuration mode, unless you use the dynamic keyword. Use this command to create a new crypto map entry or to modify an existing crypto map entry. Once a crypto map entry has been created, you cannot change the parameters specified at the global configuration level because these parameters determine which of the configuration commands are valid at the crypto map level.
For example, once a map entry has been created as ipsec-isakmp , you cannot change it to ipsec-manual or cisco ; you must delete and reenter the map entry. After you define crypto map entries, you can assign the crypto map set to interfaces using the crypto map interface IPSec command. Crypto maps provide two functions: 1 filtering and classifying traffic to be protected and 2 defining the policy to be applied to that traffic.
The first use affects the flow of traffic on an interface; the second affects the negotiation performed via IKE on behalf of that traffic. A crypto map set is a collection of crypto map entries, each with a different seq-num but the same map-name. Therefore, for a given interface, you could have certain traffic forwarded to one IPSec peer with specified security applied to that traffic, and other traffic forwarded to the same or a different IPSec peer with different IPSec security applied.
To accomplish this you would create two crypto maps, each with the same map-name , but each with a different seq-num. The seq-num Argument. The number you assign to the seq-num argument should not be arbitrary. This number is used to rank multiple crypto map entries within a crypto map set.
Within a crypto map set, a crypto map entry with a lower seq-num is evaluated before a map entry with a higher seq-num ; that is, the map entry with the lower number has a higher priority. For example, imagine that there is a crypto map set that contains three crypto map entries: mymap 10, mymap 20, and mymap The crypto map set named mymap is applied to interface Serial 0. When traffic passes through the Serial 0 interface, the traffic is evaluated first for mymap If the traffic matches a permit entry in the extended access list in mymap 10, the traffic will be processed according to the information defined in mymap 10 including establishing IPSec security associations when necessary.
If the traffic does not match the mymap 10 access list, the traffic will be evaluated for mymap 20, and then mymap 30, until the traffic matches a permit entry in a map entry. If the traffic does not match a permit entry in any crypto map entry, it will be forwarded without any IPSec security. Refer to the "Usage Guidelines" section of the crypto dynamic-map command for a discussion on dynamic crypto maps.
You should make crypto map entries which reference dynamic map sets the lowest priority map entries, so that inbound security association negotiations requests will try to match the static maps first. Only after the request does not match any of the static maps do you want it to be evaluated against the dynamic map set. To make a crypto map entry referencing a dynamic crypto map set the lowest priority map entry, give the map entry the highest seq-num of all the map entries in a crypto map set.
Create dynamic crypto map entries using the crypto dynamic-map command. After you create a dynamic crypto map set, add the dynamic crypto map set to a static crypto map set with the crypto map IPSec global configuration command using the dynamic keyword. The following example shows the minimum required crypto map configuration when IKE will be used to establish the security associations:. The following example shows the minimum required crypto map configuration when the security associations are manually established:.
The following example configures an IPSec crypto map set that includes a reference to a dynamic crypto map set. Crypto map "mymap 10" allows security associations to be established between the router and either or both of two remote IPSec peers for traffic matching access list Crypto map "mymap 20" allows either of two transform sets to be negotiated with the remote peer for traffic matching access list Creates a dynamic crypto map entry and enters the crypto map configuration command mode.
To apply a previously defined crypto map set to an interface, use the crypto map interface configuration command. To remove the crypto map set from the interface, use the no form of this command. Name that identifies the crypto map set. When the no form of the command is used, this argument is optional. Any value supplied for the argument is ignored. Use this command to assign a crypto map set to an interface. You must assign a crypto map set to an interface before that interface can provide IPSec services.
Only one crypto map set can be assigned to an interface. If multiple crypto map entries have the same map-name but a different seq-num , they are considered to be part of the same set and will all be applied to the interface.
The crypto map entry with the lowest seq-num is considered the highest priority and will be evaluated first. A single crypto map set can contain a combination of cisco , ipsec-isakmp , and ipsec-manual crypto map entries. The following example assigns crypto map set "mymap" to the S0 interface. When traffic passes through S0, the traffic will be evaluated against all the crypto map entries in the "mymap" set. To specify and name an identifying interface to be used by the crypto map for IPSec traffic, use the crypto map local-address global configuration command.
To remove this command from the configuration, use the no form of this command. The identifying interface that should be used by the router to identify itself to remote peers. If Internet Key Exchange is enabled and you are using a certification authority CA to obtain certificates, this should be the interface with the address specified in the CA certificates. If you apply the same crypto map to two interfaces and do not use this command, two separate security associations with different local IP addresses could be established to the same peer for similar traffic.
If you are using the second interface as redundant to the first interface, it could be preferable to have a single security association with a single local IP address created for traffic sharing the two interfaces. Having a single security association decreases overhead and makes administration simpler. This command allows a peer to establish a single security association and use a single local IP address that is shared by the two redundant interfaces.
If applying the same crypto map set to more than one interface, the default behavior is as follows:. However, if you use a local-address for that crypto map set, it has multiple effects:. One suggestion is to use a loopback interface as the referenced local address interface, because the loopback interface never goes down.
The following example assigns crypto map set "mymap" to the S0 interface and to the S1 interface. When traffic passes through either S0 or S1, the traffic will be evaluated against the all the crypto maps in the "mymap" set. When traffic through either interface matches an access list in one of the "mymap" crypto maps, a security association will be established.
This same security association will then apply to both S0 and S1 traffic that matches the originally matched IPSec access list. The local address that IPSec will use on both interfaces will be the IP address of interface loopback0. To specify an extended access list for a crypto map entry, use the match address crypto map configuration command. To remove the extended access list from a crypto map entry, use the no form of this command.
Optional Identifies the extended access list by its name or number. This value should match the access-list-number or name argument of the extended access list being matched. Optional Identifies the named encryption access list. This name should match the name argument of the named encryption access list being matched. This command is required for all static crypto map entries. If you are defining a dynamic crypto map entry with the crypto dynamic-map command , this command is not required but is strongly recommended.
Use this command to assign an extended access list to a crypto map entry. You also need to define this access list using the access-list or ip access-list extended commands. The extended access list specified with this command will be used by IPSec to determine which traffic should be protected by crypto and which traffic does not need crypto protection.
Traffic that is permitted by the access list will be protected. Traffic that is denied by the access list will not be protected in the context of the corresponding crypto map entry. Note that the crypto access list is not used to determine whether to permit or deny traffic through the interface.
An access list applied directly to the interface makes that determination. The crypto access list specified by this command is used when evaluating both inbound and outbound traffic. If necessary, in the case of static IPSec crypto maps, new security associations are established using the data flow identity as specified in the permit entry; in the case of dynamic crypto map entries, if no SA exists, the packet is dropped.
In the case of IPSec, the access list is also used to identify the flow for which the IPSec security associations are established. In the outbound case, the permit entry is used as the data flow identity in general , while in the inbound case the data flow identity specified by the peer must be "permitted" by the crypto access list.
The following example shows the minimum required crypto map configuration when IKE will be used to establish the security associations. This example is for a static crypto map. To change the mode for a transform set, use the mode crypto transform configuration command.
To reset the mode to the default value of tunnel mode, use the no form of the command. Optional Specifies the mode for a transform set: either tunnel or transport mode. If neither tunnel nor transport is specified, the default tunnel mode is assigned. Use this command to change the mode specified for the transform. This setting is only used when the traffic to be protected has the same IP addresses as the IPSec peers this traffic can be encapsulated either in tunnel or transport mode.
This setting is ignored for all other traffic all other traffic is encapsulated in tunnel mode. If the traffic to be protected has the same IP address as the IP Security peers and transport mode is specified, during negotiation the router will request transport mode but will accept either transport or tunnel mode. If tunnel mode is specified, the router will request tunnel mode and will accept only tunnel mode.
After you define a transform set, you are put into the crypto transform configuration mode. While in this mode you can change the mode to either tunnel or transport. This change applies only to the transform set just defined. If you do not change the mode when you first define the transform set, but later decide you want to change the mode for the transform set, you must re-enter the transform set specifying the transform name and all its transforms and then change the mode.
If you use this command to change the mode, the change will only affect the negotiation of subsequent IPSec security associations via crypto map entries which specify this transform set. If you want the new settings to take effect sooner, you can clear all or part of the security association database. See the clear crypto sa command for more details. With tunnel mode, the entire original IP packet is protected encrypted, authenticated, or both and is encapsulated by the IPSec headers and trailers an Encapsulation Security Protocol header and trailer, an Authentication Header, or both.
Then a new IP header is prefixed to the packet, specifying the IPSec endpoints as the source and destination. Tunnel mode can be used with any IP traffic. For example, tunnel mode is used with Virtual Private Networks VPNs where hosts on one protected network send packets to hosts on a different protected network via a pair of IPSec peers. With VPNs, the IPSec peers "tunnel" the protected traffic between the peers while the hosts on their protected networks are the session endpoints.
With transport mode, only the payload data of the original IP packet is protected encrypted, authenticated, or both. Use transport mode only when the IP traffic to be protected has IPSec peers as both the source and destination. For example, you could use transport mode to protect router management traffic. Specifying transport mode allows the router to negotiate with the remote peer whether to use transport or tunnel mode.
The following example defines a transform set and changes the mode to transport mode. The mode value only applies to IP traffic with the source and destination addresses at the local and remote IPSec peers. Defines a transform set—an acceptable combination of security protocols and algorithms. To specify an IP Security peer in a crypto map entry, use the set peer crypto map configuration command.
To remove an IPSec peer from a crypto map entry, use the no form of this command. Specifies the IPSec peer by its host name. This command is required for all static crypto maps. If you are defining a dynamic crypto map with the crypto dynamic-map command , this command is not required, and in most cases is not used because, in general, the peer is unknown. For ipsec-isakmp crypto map entries, you can specify multiple peers by repeating this command.
The peer that packets are actually sent to is determined by the last peer that the router heard from received either traffic or a negotiation request from for a given data flow. If the attempt fails with the first peer, Internet Key Exchange tries the next peer on the crypto map list.
For ipsec-manual crypto entries, you can specify only one IPSec peer per crypto map. If you want to change the peer, you must first delete the old peer and then specify the new peer. The following example shows a crypto map configuration when IKE will be used to establish the security associations.
In this example, a security association could be set up to either the IPSec peer at To specify that IP Security should ask for perfect forward secrecy PFS when requesting new security associations for this crypto map entry, or that IPSec requires PFS when receiving requests for new security associations, use the set pfs crypto map configuration command.
By default, PFS is not requested. If no group is specified with this command, group1 is used as the default. This command is only available for ipsec-isakmp crypto map entries and dynamic crypto map entries. During negotiation, this command causes IPSec to request PFS when requesting new security associations for the crypto map entry.
The default group1 is sent if the set pfs statement does not specify a group. If the peer initiates the negotiation and the local configuration specifies PFS, the remote peer must perform a PFS exchange or the negotiation will fail. If the local configuration does not specify a group, a default of group1 will be assumed, and an offer of either group1 or group2 will be accepted.
PFS adds another level of security because if one key is ever cracked by an attacker then only the data sent with that key will be compromised. Without PFS, data sent with other keys could be also compromised. This exchange requires additional processing time. The bit Diffie-Hellman prime modulus group, group2 , provides more security than group1 , but requires more processing time than group1.
The following example specifies that PFS should be used whenever a new security association is negotiated for the crypto map "mymap 10":. To specify that one security association should be requested for each crypto map access list permit entry, use the no form of this command.
For a given crypto map, all traffic between two IPSec peers matching a single crypto map access list permit entry will share the same security association. This command is only available for ipsec-isakmp crypto map entries and is not supported for dynamic crypto map entries. Normally, within a given crypto map, IPSec will attempt to request security associations at the granularity specified by the access list entry.
For example, if the access list entry permits IP protocol traffic between subnet A and subnet B, IPSec will attempt to request security associations between subnet A and subnet B for any IP protocol , and unless finer-grained security associations are established by a peer request , all IPSec-protected traffic between these two subnets would use the same security association.
In this case, each host pairing where one host was in subnet A and the other host was in subnet B would cause IPSec to request a separate security association. With this command, one security association would be requested to protect traffic between host A and host B, and a different security association would be requested to protect traffic between host A and host C. The access list entry can specify local and remote subnets, or it can specify a host-and-subnet combination.
If the access list entry specifies protocols and ports, these values are applied when establishing the unique security associations. Use this command with care, as multiple streams between given subnets can rapidly consume system resources. The following example shows what happens with an access list entry of permit ip 1. Without the per-host level, any of the above packets will initiate a single security association request originated via permit ip 1. To override for a particular crypto map entry the global lifetime value, which is used when negotiating IP Security security associations, use the set security-association lifetime crypto map configuration command.
This command is available only for ipsec-isakmp crypto map entries and dynamic crypto map entries. Assuming that the particular crypto map entry has lifetime values configured, when the router requests new security associations during security association negotiation, it will specify its crypto map lifetime value in the request to the peer; it will use this value as the lifetime of the new security associations.
If you change a lifetime, the change will not be applied to existing security associations, but will be used in subsequent negotiations to establish security associations for data flows supported by this crypto map entry. Refer to the clear crypto sa command for more detail. To change the timed lifetime, use the set security-association lifetime seconds form of the command.
The timed lifetime causes the keys and security association to time out after the specified number of seconds have passed. To change the traffic-volume lifetime, use the set security-association lifetime kilobytes form of the command. Shorter lifetimes can make it harder to mount a successful key recovery attack, because the attacker has less data encrypted under the same key to work with.
However, shorter lifetimes need more CPU processing time. The lifetime values are ignored for manually established security associations security associations installed via an ipsec-manual crypto map entry. Assuming that the particular crypto map entry does not have lifetime values configured, when the router requests new security associations it will specify its global lifetime values in the request to the peer; it will use this value as the lifetime of the new security associations.
When the router receives a negotiation request from the peer, it will use the smaller of either the lifetime value proposed by the peer or the locally configured lifetime value as the lifetime of the new security associations. The security association and corresponding keys will expire according to whichever occurs sooner, either after the seconds time out or after the kilobytes amount of traffic is passed. The following example shortens the timed lifetime for a particular crypto map entry, because there is a higher risk that the keys could be compromised for security associations belonging to the crypto map entry.
The traffic-volume lifetime is not changed because there is not a high volume of traffic anticipated for these security associations. The timed lifetime is shortened to seconds 45 minutes. Changes global lifetime values used when negotiating IPSec security associations. To manually specify the IP Security session keys within a crypto map entry, use the set session-key crypto map configuration command.
This command is only available for ipsec-manual crypto map entries. If you only have a couple of special instructions or a co-processor that accelerates some part of the cryptographic function, then you may want to replace only the relevant functions in the Mbed TLS module.
If you want to replace functions in the ECP module, you need to implement the mandatory utility functions:. If the answer is no, then Mbed TLS will fall back to the software implementation to continue the operation. Use them to optimize if you are replacing a function in the ECP module. Because Mbed TLS is implemented as a static link library in Arm Mbed OS, you also have to notify the compiler or linker that the alternative implementations are present.
To do this, you have to set the macros corresponding to the selected functions. You can read more on this in the subsection about setting macros. These functions have the same name as the ones they replace. There is a doxygen documentation for the original functions.
Create a pull request when your code is finished and production ready. You may create a directory structure similar to the one you have for the HAL if you feel it appropriate. Mbed TLS supports only curves over prime fields and uses mostly curves of short Weierstrass form.
The only Montgomery curve supported is Curve The method of accelerating the ECP module may support different kinds of elliptic curves. If that acceleration is a hardware accelerator, you may need to indicate what kind of curve operation the accelerator has to perform by setting a register or executing a special instruction. If performing this takes significant amount of time or power, then you may not want Mbed TLS to do this step unnecessarily.
The replaceable functions in this module are relatively low level, and therefore it may not be necessary to do this initialization and release in each of them. You will have to set some macros to notify Mbed TLS and the compiler or linker about the presence of your functions or module implementation. The best way to do this is to supply a target-specific configuration file for your target. First, you need to notify the build system that you to have a target-specific Mbed TLS configuration.
In targets. Replacing the whole module is the harder way, because it usually takes much more effort than providing alternatives for a handful of functions. It is also less safe, not just because taking this road can cause complications during the maintenance period, but also because it can lead to increased security risks. For example, if the alternative module implementation contains the duplicate of some Mbed TLS code, then keeping it up to date is an extra effort; not doing so may raise security risks.
Implement the functionality of the whole module. Your implementation has to leave unchanged the function prototypes, and the names of any global type, variable or macro. Provide a header file for your implementation. The ECP module is split to two files: ecp. Some hardware accelerators require initialization, regardless of the specific cryptography engine. Note that functions in Mbed TLS can be called from multiple threads and from multiple processes at the same time.
Because hardware accelerators are usually a unique resource, it is important to protect all functions against concurrent access. For short actions, disabling interrupts for the duration of the operation may be enough. When it is not desirable to prevent context switches during the execution of the operation, you must protect the operation with a mutual exclusion primitive such as a mutex.
Make sure to unlock the mutex or restore the interrupt status when returning from the function even if an error occurs. The current framework does not provide an interface to initialize and shut down accelerator hardware. One approach is to perform any necessary hardware initialization during system startup outside of Mbed TLS ; however this may not be desirable for power consumption reasons.
At the other end of the spectrum, it is possible to initialize the hardware at the beginning of each function and shut it down after reading the results. This is a viable strategy if initialization is cheap enough. If it is neither desirable to leave the hardware powered on permanently nor to initialize it each time, you need to determine a power management strategy according to the expected application usage.
A more useful strategy is to keep a global use counter: increment the counter as part of context allocation and decrement it as part of freeing each context. When the global counter drops to 0, the hardware is no longer in use. In specialized applications, it may be best to provide a custom function to switch the hardware on and off and let the application developer decide when to call it.
