摘要： 基于计算Diffi}Hellman问题的困难假设，构造了一个基于身份的代理聚合签名方案。该方案不仅满足代理签名的各种安全性要求，而且具有聚合签名的优点。最后，利用双线性技术对方案的正确性进行了严格的证明，并给出了方案安全性的详细证明。结果表明方案是可证安全的和可靠的，是一种安全有效的方案。

Abstract: Based on the hardness of the computational Diffie-Hellman problem, this paper proposed an identity-based proxy aggregate signature. hhe scheme not only owns all the secure properties of proxy signature, but also has merit of the aggregate signature. At last, the scheme's correctness was exactly proven in terms of bilinear pairing technique, and its security analysis was given in detail. It is indicated that this scheme is proven secure and reliable. Therefore, this scheme is secure and efficient.
Key words: Proxy aggregate signature, Identity based cryptography, Bilinear pairing, Computational DifficHcllman problem
