A New Mediated Certificateless Signature Scheme
Liang Hong-mei · Journal of Zhangzhou Normal University · 2008
Certificateless public key cryptography eliminates the key-escrow problem of identity-based cryptography and also preserves all of its advantages.For obtaining instantaneous revocation of a user’s public key,Boneh et al.introduced an efficient method in RSA-based cryptography,and presented the concept of security-mediated cryptography in 2001.In PKC 2004,Sherman et al.introduced the formal definition of security-mediated certificateless cryptography,present a generic construction and also a concrete encryption scheme,and give the security model,but they did not present signature scheme.This paper propose a new security-mediated certificateless signature scheme from Bilinear pairing.
