An Analysis of RMAC
Abstract
A recent trend in message authentication is the use of a randomizing parameter, such that the authentication tag is based not only on the message and the key, but a public nonce which is changed for every authenticated message. This generally affords a better security proof. However, several new classes of attacks are made available by these techniques. We examine these attacks, and apply some of them to RMAC, a recently published MAC mechanism.
