Improvement on Shamir's Id-based Signature Scheme
Wei Zhang · Journal of Nanjing University of Posts and Telecommunications · 2010
In 2001,Cao et al.introduced an improved RSA cryptosystem,which can be proved based on factorization of a large number.In this paper,we improve Shamir's Id-based signature scheme(IBS) by using the improved RSA cryptosystem,and provide a formal security proof.The proposed IBS scheme is more reliable and efficient than the original Shamir' scheme.
