一种基于身份原始签名者和基于证书代理签名者的代理签名体制
Proxy signature scheme for ID-based original signers and certificate-based proxy signers
摘要
Abstract
To realize delegation between different users in a mixed cryptosystem, a proxy signature scheme for ID-based original signers and certificated-based proxy signers (PSS-ID- CER) is defined. Using the bilinear properties of the pairings and the characters of key generations of certificate-based cryptosystems and ID-based cryptosystems, a construction for such a scheme is also presented. To prove the security of the proposed scheme, a general security model for this scheme under adaptive chosen-PKG, chosen-ID, chosen-delegation, chosen-ProxySigner-public-key, chosen-proxy-key and chosen-message attack is defined. The proposed scheme is provably secure under the random oracle model and the hardness assumption of computational Diffie-Hellman problem.关键词
