On the Security of HFE, HFEv- and Quartz
asymmetric cryptography finite fields multivariate cryptanalysis
2009/4/15
Quartz is a signature scheme based on an HFEv- trapdoor
function published at Eurocrypt 1996. In this paper we study ”inversion”
attacks for Quartz, i.e. attacks that solve the system of multivariat...
Short Signatures, Provable Security, Generic Attacks and Computational Security of Multivariate Polynomial Schemes such as HFE, Quartz and Sflash
Generic signature schemes short signatures provable security
2009/3/27
The object of this paper is the concrete security of recent
multivariate signature schemes. A major challenge is to reconcile some
”tricky” ad-hoc constructions that allow to make short signatures, ...
