Analysis and Improvement of Secure and Efficient Certificateless Signature Scheme
摘要
Abstract
The security analysis of the certificateless signature scheme proposed by Liu Qian et al. shows that the scheme is not secure for public key replacement attack and the efficiency of the scheme is low due to the usage of bilinear pairings. This paper proposes a new certificateless signature scheme without bilinear pairings on the basis of original scheme, and it is proved that the new scheme is secure for two types of attackers. After comparing the new scheme with existing signature schemes, it maintains that the new scheme is efficient.关键词
