We analyze the security of some variants of the CFS code-based digital signature scheme. We show how the adoption of some code-based hash functions to improve the efficiency of CFS leads to the ability of an attacker to produce a forgery compatible with the rightful user’s public key.

Abstract
We analyze the security of some variants of the CFS code-based digital signature scheme. We show how the adoption of some code-based hash functions to improve the efficiency of CFS leads to the ability of an attacker to produce a forgery compatible with the rightful user’s public key.File in questo prodotto:
