Abstract
In this paper, we give the full key-recovery attacks on the HMAC/NMAC instantiated with 3 and 4-Pass HAVAL using our new differential paths. The complexity to recover the inner key is about 2103 MAC queries for the 3-Pass HAVAL and 2123 MAC queries for the 4-Pass HAVAL. The complexity to recover the outer key is about 269 MAC queries and 2198 offline computations for the 3-Pass HAVAL based HMAC/NMAC. For the 4-Pass HAVAL case, the number of MAC queries for outer key-recovery is about 2103 and the offline work is about 2180 4-Pass HAVAL computations. © 2009 Springer Berlin Heidelberg.
