Abstract :
In 2002, Wu and Hsu proposed two new ID-based multisignature schemes that are suitable for the sequential and the broadcasting architectures, respectively. They claimed that these two schemes cannot be broken due to the difficulty of factorization. In this paper, we prove that the Wu-Hsu multisignature schemes can be broken by Euclidean algorithm with known signature attack.
