Higher Order Differential Cryptanalysis of Multivariate Hash Functions
Abstract
In this paper, we analyze the security of multivariate hash functions and conclude that low degree multivariate functions such as MQ-HASH are neither pseudo-random nor unpredictable. And they are also not computation-resistance, which makes MAC forgery easily.
