引用

2010 4th International Conference on intelligent Information Technology Application (IITA2010)

作者： Fanyu Kong Institute of network Security Shandong university jinan 250100 china Jia Yu College of Information Engineering Qingdao university Qingdao 266071 china

In 2009, S. Akleylek et al. and R. Tso et al. proposed two efficient short signature schemes from bilinear pairings separately. In this paper, we propose the key substitution attacks on the two short signature schemes. Our attacks show that the malicious attacker can generate a valid signature, which can be verified by a forged public key, from a legitimate user’s public key and a signature on some message m. Therefore, S. Akleylek et al.’s scheme and R. Tso et al.’s scheme are insecure against the key substitution attack.
