Specifies management techniques for keys used in the authentication, encryption and decryption of electronic messages relating to financial transactions using session keys.

This Standard specifies management techniques for keys used in the authentication, encipherment and decipherment of electronic messages relating to financial transactions using session keys.In particular, this Standard—(a) defines security interface procedures between nodes;(b) defines methods of interchange of the various encipherment keys used for securing transactions; and(c) ensures that messages can only be authenticated at their correct destination.NOTE: Principles concerning key management and physical security are dealt with in AS 2805.6.1.
