Security Analysis of Two Self-certified Public Key Signature Schemes
Huang Hui · Journal of Zhangzhou Normal University · 2010
In this paper,we analysis the two self-certified public key signature schemes recently proposed by Lin et al.and Wang et al.respectively.Unfortunately,the above two schemes are insecure,because they can suffer from the attack from the replacement public key so that any one can forge a valid signature on any message.Moreover,in all the self-certified public key signature schemes available nowadays,none of them consider the attack from the replacement public key.Thus,we get the enlightenment: because of the autologous feature of the self-certified public key signature scheme,the attack from the replacement public key must be taken into consideration in the security model of the self-certified public key signature scheme to guarantee the real security.
