We consider the security of message authentication code (MAC) algorithms, and the
construction of MACs from fast hash functions. A new forgery attack applicable to all iterated …

The security of iterated message authentication code (MAC) algorithms is considered, and in
particular, those constructed from unkeyed hash functions. A new MAC forgery attack …

This paper discusses key recovery and universal forgery attacks on several MAC algorithms
based on universal hash functions. The attacks use a substantial number of verification …

HMAC is a widely used message authentication code and a pseudorandom function
generator based on cryptographic hash functions such as MD5 and SHA-1. It has been …

We describe a message authentication algorithm, UMAC, which can authenticate messages
(in software, on contemporary machines) roughly an order of magnitude faster than current …

The use of cryptographic hash functions like MD5 or SHA-1 for message authentication has
become a standard approach in many applications, particularly Internet security protocols …

Hash functions are important in modern cryptography. Main applications are their use in
conjunction with digital signa ture schemes and message authentication. Hash functions …

This document describes HMAC, a mechanism for message authentication using
cryptographic hash functions. HMAC can be used with any iterative cryptographic hash …
