If a PIV Card Application implements the optional secure messaging protocol for non-card-management operations, it shall be implemented as specified in this section. Secure messaging is initiated through the use of a key establishment protocol. The key establishment protocol defined here is a one-way authentication protocol that authenticates the PIV Card Application to the client application and establishes a set of session keys that may be subsequently used to protect the communication channel between the two parties. 13 PIV Cards may implement a different secure messaging protocol for card management operations. Such a protocol is outside of the scope of this document, however, if it is to be used for remote post issuance updates it shall satisfy the requirements of [FIPS201 , Section 2.9.2].

Section 4.1 describes the key establishment protocol used to support secure messaging in the PIV Card Application. Section 4.2 describes the use of secure messaging to protect commands and responses sent between the client application and the PIV Card Application.
