两个高效无证书签名方案的替换公钥攻击
PUBLIC-KEY REPLACEMENT ATTACK AGAINST TWO EFFICIENT CERTIFICATELESS SIGNATURE SCHEMES
摘要
Abstract
We analyse the security of two efficient certificateless signature schemes presented recently, and point out that they can all suffer from the public-key replacement attack.Any attacker can forge valid signature successfully on the message optionally selected by replacing the keys of the singers.We also analyse the primary reason of the public-key replacement attack against these two signature schemes.Finally, through these two attacks we summarise and analyse some key points that have to pay attention to in the process of certificateless signature schemes design, which is of referential significance to the design of the certificateless signature schemes.关键词
