Attack and Improvement for Certificateless Signature Scheme
摘要
Abstract
For the security problem, which is insecure against public-key replacement attack, on the certificateless signature scheme proposed by Su et al.'s, this paper proposes an improved certificateless signature scheme. The proposed scheme simplifies the process of verification. Analysis results show that the improved scheme is secure against public-key replacement attack and is provably secure against existential forgery under adaptively chosen message attack in the random oracle model.关键词
