Related-Key and Key-Collision Attacks Against RMAC

Tadayoshi Kohno

Abstract

In [JJV02] Jaulmes, Joux, and Valette propose a new randomized message authentication scheme, called RMAC, which NIST is currently in the process of standardizing [NIS02]. In this work we present several attacks against RMAC. The attacks are based on a new protocol-level related-key attack against RMAC and can be considered variants of Biham's key-collision attack [Bih02]. These attacks provide insights into the RMAC design. We believe that the protocol-level related-key attack is of independent interest.
