Higher Order Differential Cryptanalysis of Multivariate Hash Functions
Yiyuan Luo and Xuejia Lai
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.
