【国外标准】 Information security - Key management - Part 3: Mechanisms using asymmetric techniques

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, b) Establish a shared secret key for use in a symmetric cryptographic technique between two entities A and B via key transport, and 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.
