ISAKMP
Internet Security Association & Key Management Protocol. A leading candidate for Internet key management being considered by the IP Security Working Group of the IETF. ISAKMP provides a framework for authentication and encryption for many different key exchange methodologies. ISAKMP requires that at least one pair of messages be exchanged between the communicating peers before a secure link can be established.
