Keywords : cryptanalysis, digital signature schemes, RSA variants
Abstract : We describe adaptive attacks on several variants of the RSA signature scheme by de Jonge and Chaum. Moreover, we show how to break Boyd's scheme with an adaptive, a directed and a known signature attack. The feasibility of the adaptive attack on Boyd's scheme is illustrated by a concrete example.
