Abstract :
Recently, Seung-Hyun et al proposed a nominative proxy signature scheme for mobile communication. However, we show that the scheme hasn´t nonrepudiation, note that a malicious original signer can forge the proxy signer to sign on any message. Finally, we also present a modification of the scheme to repair the security flaw.
