ID-Based signature scheme is a kind of public key signature scheme which uses the user's identity as the public key. Compared to the PKI system, no certificate is needed in the ID-Based cyrptosystem. In this paper, we proposed an identity-based signature scheme. We give the security proof under the q-SDH assumption without using random oracle model. Our security model is based on the generalization of selective ID modelin [6]. Our scheme is efficient in computation cost compared to [3] and we have a relatively tight security reduction under our security model. |
