Welcome to the resource topic for 2004/143
Title:
Short Signatures, Provable Security, Generic Attacks and Computational Security of Multivariate Polynomial Schemes such as HFE, Quartz and Sflash
Authors: Nicolas T. Courtois
Abstract:This paper should be considered as a draft.
Part of it is an extended version
of the paper Generic Attacks and the Security of Quartz presented at PKC 2003 and at the second Nessie workshop. It also contains a lot of new material that is not published elsewhere:
-(yet another) discussion about what is and what isn’t a secure signature scheme
-up-to-date security results fo Sflash and Quartz
-new results on computational security of Sflash w.r.t algebraic relation attacks in the light of Faugère-Joux Crypto 2003 paper.
-and more…
Comments are welcome !
