Abstract :
Identity-based cryptosystem was proposed in order to simplify key management procedures of certificate-based public key infrastructures. In our paper, it is intended to build an efficient and provably secure ID-based signature (IBS) scheme. The proposed IBS is provably secure against existential forgery for adaptive chosen message and identity attack in the random oracle model based on a reasonably well-explored hardness assumption.
