This document specifies MAC algorithms suitable for applications requiring lightweight cryptographic mechanisms. These mechanisms can be used as data integrity mechanisms to verify that data has not been altered in an unauthorized manner. They can also be used as message authentication mechanisms to provide assurance that a message has been originated by an entity in possession of the secret key.Cross References:ISO/IEC 18033-3ISO/IEC 29192-2ISO/IEC 29192-5ISO/IEC 10118-3ISO/IEC 9797-1IEC 80000-13ISO/IEC 10118-1All current amendments available at time of purchase are included with the purchase of this document.
