摘要: 代理签名方案允许代理签名者代表原始签名人生成代理签名。Mambo等人首次引入了代理签名的概念,目前在这个领域上有大量的研究工作。为了简化密钥管理,研究人员提出了许多基于身份的代理签名方案。但许多现有的方案容易受到基于代理密钥泄露的攻击。有必要针对代理密钥,提出一个基于身份的代理签名方案的安全模型。基于双线性映射提出了一个有效的方案,并在随机领言模型中证明是安全的。新方案在代理密钥泄露时仍然是安全的。

关键词: 数字签名, 代理签名, 基于身份的签名, 双线性映射, 随机领言模型

Abstract: Proxy signature schemes allow a proxy signer to generate proxy signatures on behalf of an original signer. Mambo, et ah first introduced the notion of proxy signature and a lot of research work can be found on this topic nowadays. To simplify key management, many identity based proxy signature schemes were proposed. However, some existing schemes are vulnerable to proxy key exposure attack. It is necessary to propose a security model for identity based proxy signature schemes against proxy key exposure attack. Then an efficient scheme based on pairings was presented, which is provably secure in the random oracle model. In particular, the new scheme is secure against proxy key exposure attack

Key words: digital signature, proxy signature, identity based signature, bilinear pairing, random oracle model
