Abstract: Chang et al. proposed a new digital signature scheme with message recovery. However, several forgery attacks demonstrated that Chang et al.'s construction without using one-way hash functions and message redundancy is insecure. Nevertheless, it is unclear to see how to achieve the attacks. In this paper, more general forgery attacks are described to show clearly how to obtain these attacks. It is interesting that our general forgery covers all the known attacks.

Keywords: digital signatures; message recovery; forgery attacks; information security.
