DU Hongzhen. Provable secure ID-based threshold proxy signature scheme
摘要
Abstract
Based on the Paterson’s identity-based signature scheme, this paper proposes a provable secure identity-based threshold proxy signature scheme. The scheme is existentially unforgeable against adaptive chosen message attacks under the computational Diffie-Hellman assumption in the standard model. Compared with other threshold proxy signature schemes based on public key cryptosystem, the new scheme is more secure. Compared with other identity-based threshold proxy signature schemes in the random oracle model, the new scheme is more meaningful.关键词
