Abstract :
In 2005, Hsu et al.´s proposed a new proxy multi-signature schemes which was more efficient in terms of the communication costs and the computational compared with Yi et al´s scheme which was proposed in 2000. However, their schemes suffer from some drawbacks. In this paper we show that their schemes are insecure against the original signers´ forgery
