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