Abstract: It is found that Chang et al.'s signature scheme with message recovery is not as secure as they claimed, in fact. In this letter, two forgery attacks is proposed to show that the signature can be forged on any uncontrolled messages. To overcome these attacks, the one-way hash functions and the message redundancy schemes may be still used.
