Abstract
PreviewThis 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.
