A New Efficient Leakage-Free Certificateless Signature
Zhuo Gao, Liang Hu, Hongtu Li · 2017
Digital signature, a cryptographic algorithm, provides integrity, authentication and non repudiation messages.In the literature, several certificateless signature schemes have been designed.However, most of them are vulnerable to the ephemeral secret leakage (ESL) attack.We propose a new secure certificateless signature scheme which can resist ESL attacks.Moreover, we prove the security of two types of adversaries in certificateless signature schemes.The proposed scheme provides unforgeability based on the hardness assumption of CDH problem.
