Encryption scheme of certificateless and leakage-resilient private key
Journal of Computer Applications · 2014
A lot of side channel attacks and cold boot attacks can leak secret information of cryptographic systems and destroy the security of traditional cryptographic schemes.This paper presented a certificateless encryption scheme which can resist the private key leakage.Based on the q-ABDHE(Augmented Bilinear Diffie-Hellman Exponent) hypothesis,the security of the scheme was proved.The leakage-resilient property was obtained via extractor.The leakage-resilient performance was analyzed.The theoretical analyses show that the relative leakage rate of private key can reach 1/8.
