Abstract: Recently, Chang \textit{et al}. \cite{Chang} proposed a new digital signature scheme with message recovery and claimed that neither one-way hash functions nor message redundancy schemes were employed in their scheme. However, in this letter, two forgery attacks are proposed to show that Chang \textit{et al.}'s signature scheme is not secure. To resist these attacks, the message redundancy schemes may be still used.
