Résumé

This part of ISO/IEC 9798 specifies entity authentication mechanisms using a cryptographic check function. Two

mechanisms are concerned with the authentication of a single entity (unilateral authentication), while the remaining

are mechanisms for mutual authentication of two entities.

The mechanisms specified in this part of ISO/IEC 9798 use time variant parameters such as time stamps,

sequence numbers, or random numbers, to prevent valid authentication information from being accepted at a later

time or more than once.

If a time stamp or sequence number is used, one pass is needed for unilateral authentication, while two passes are

needed to achieve mutual authentication. If a challenge and response method employing random numbers is

used, two passes are needed for unilateral authentication, while three passes are required to achieve mutual

authentication.

Examples of cryptographic check functions are given in ISO/IEC 9797.
