NIST SP 800-56A

Identifier - A bit string that is associated with a person, device or organization. It may be an identifying name, or may be something more abstract (for example, a string consisting of an IP address and timestamp). If a party owns a static key pair that is used in a key agreement transaction, then the identifier assigned to that party is one that is bound to that static key pair. If the party does not contribute a static public key as part of a key agreement transaction, then the identifier of that party is a non-null identifier selected in accordance with the protocol utilizing the scheme.
