Title

Distribution of Ephemeral Public Keys

Control

When used, ephemeral public keys are distributed as part of a secure key-agreement protocol. The key-agreement process (i.e., the key-agreement scheme + the protocol + key confirmation + any associated negotiation + local processing) should provide a recipient with the assurances listed in Section 8.1.5.1.1 . The recipient of an ephemeral public key shall obtain assurance of validity of that key as specified in [SP800-56A] prior to using that key for subsequent steps in the key-agreement process.
