### Paper: Musings on the Wang et al. MD5 Collision

Authors: Philip Hawkes Michael Paddon Gregory G. Rose URL: http://eprint.iacr.org/2004/264 Search ePrint Search Google Wang et al. caused great excitement at CRYPTO2004 when they announced a collision for MD5~\cite{R92_MD5}. This paper is examines the internal differences and conditions required for the attack to be successful. There are a large number of conditions that must be satisfied, thus indicating Wang at al. have found a clever way to generate message pairs for which the conditions are satisfied. The large number of conditions suggests that an attacker cannot use these differentials to cause second pre-image attacks with complexity less than generic attacks. Initial examination also suggests that an attacker cannot cause such collisions for HMAC-MD5 with complexity less than generic attacks.
