| Abstract(in English) | 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 cryptosystem. 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 model in. Our scheme is efficient in computation cost compared to and we have a relatively tight security reduction under our security model. |
