This document defines key management mechanisms based on asymmetric cryptographic techniques. It specifically addresses the use of asymmetric techniques to achieve the following goals. a) Establish a shared secret key for use in a symmetric cryptographic technique between two entities A and B by key agreement. In a secret key agreement mechanism, the secret key is computed as the result of a data exchange between the two entities A and B. Neither of them is able to predetermine the value of the shared secret key.
b) Establish a shared secret key for use in a symmetric cryptographic technique between two entities A and B via key transport. In a secret key transport mechanism, the secret key is chosen by one entity A and is transferred to another entity B, suitably protected by asymmetric techniques.
c) Make an entity's public key available to other entities via key transport. In a public key transport mechanism, the public key of entity A is transferred to other entities in an authenticated way, but not requiring secrecy.
