Information technology — Security techniques — Key management — Part 3: Mechanisms using asymmetric ...
ISO/IEC 11770-3:2015 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…
