As a specific signature, the nominative proxy signature scheme is a method in which the designated proxy signer generates a nominative signature and transmits it to a verifier, instead of the original signer. Recently, Seo et al. proposed a nominative proxy signature scheme for mobile communication and claimed that the scheme hash non-repudiation. However, after analyzing the scheme, we show that the scheme is insecure and cannot provide non-repudiation, note that a malicious original signer can forge the proxy signer to sign on any message. Finally, we also present a modification version of the scheme to repair the security flaw.
