A Study of the Security of Unbalanced Oil and Vinegar Signature Schemes [PDF]
Lecture Notes in Computer Science, 2005 The Unbalanced Oil and Vinegar scheme (UOV) is a signature scheme based on multivariate quadratic equations. It uses m equations and n variables. A total of v of these are called “vinegar variables”. In this paper, we study its security from several points of view.

Unbalanced Oil and Vinegar Signature Schemes [PDF]
Lecture Notes in Computer Science, 1999 In [16], J. Patarin designed a new scheme, called "Oil and Vinegar", for computing asymmetric signatures. It is very simple, can be computed very fast (both in secret and public key) and requires very little RAM in smartcard implementations. The idea consists in hiding quadratic equations in n unknowns called "oil" and v = n unknowns called "vinegar ...

Across species: A comparative perspective on red cell homeostasis and its influence on our understanding of human physiology and disease. [PDF]
Br J HaematolThis review highlights how studies on animal red cells have enriched our understanding of the behaviour of those from humans. A comparative perspective has enhanced our knowledge of human red cell pathophysiology Summary This review emphasises how studies on animal red cells have enriched our understanding of the behaviour of those from humans.

Block-Anti-Circulant Unbalanced Oil and Vinegar
Lecture Notes in Computer Science, 2020 We introduce a new technique for compressing the public keys of the UOV signature scheme that makes use of block-anti-circulant matrices. These matrices admit a compact representation as for every block, the remaining elements can be inferred from the first row.

Towards Provable Security of the Unbalanced Oil and Vinegar Signature Scheme under Direct Attacks [PDF]
Lecture Notes in Computer Science, 2010 In this paper we show that solving systems coming from the public key of the Unbalanced Oil and Vinegar (UOV) signature scheme is on average at least as hard as solving a certain quadratic system with completely random quadratic part. In providing lower bounds on direct attack complexity we rely on the empirical fact that complexity of solving a non ...

An Improved Identity-Based Multivariate Signature Scheme Based on Rainbow
Cryptography, 2019 Multivariate Public Key Cryptography (MPKC) is one of the main candidates for post-quantum cryptography, especially in the area of signature schemes. In this paper, we instantiate a certificate Identity-Based Signature (IBS) scheme based on Rainbow, one ...

Side-Channel Attacks on Post-Quantum Signature Schemes based on Multivariate Quadratic Equations
Transactions on Cryptographic Hardware and Embedded Systems, 2018 In this paper, we investigate the security of Rainbow and Unbalanced Oil-and-Vinegar (UOV) signature schemes based on multivariate quadratic equations, which is one of the most promising alternatives for post-quantum signature schemes, against side ...
