Cryptanalysis of Variants of UOV
Lecture Notes in Computer Science, 2006 The Unbalanced Oil and Vinegar scheme (UOV) is a signature scheme based on multivariate quadratic equations. It has o oil variables and v vinegar variables. UOV has m equations and n variables, where m = o and n = v + o. In this paper, we define the weak key of UOV and study how to find the weak key from the public key.

Key recovery attack on Circulant UOV/Rainbow
JSIAM Letters, 2019 Summary: UOV and Rainbow are multivariate signature schemes, which are known to be efficient and secure enough against known attacks under suitable parameter selections, and have been expected to be post-quantum cryptography. Recently, new variants of UOV and Rainbow, called Circulant UOV and Circulant Rainbow respectively, were proposed by \textit{Z ...

Linear Recurring Sequences for the UOV Key Generation [PDF]
Lecture Notes in Computer Science, 2011 Multivariate public key cryptography is one of the main approaches to guarantee the security of communication in the post-quantum world. Due to its high efficiency and modest computational requirements, multivariate cryptography seems especially appropriate for signature schemes on low cost devices.
