基于身份的代理批量签名

Identity-based Proxy Batch Signature

利用椭圆曲线上的双线性映射和基于身份签名的思想,提出基于身份的代理批量签名方案。该方案兼具代理签名和批量签名的优点,可以有效地防止授权人冒充代理人对消息进行签名,代理人可以实现多个消息的一次签名,且每条消息能够独立地进行验证。实验表明,该方案在效率、安全性等方面都有了明显的提高。

By using of bilinear map and ideas of ID-based signature, a new efficient ID-based proxy batch signature is proposed. The scheme combines the advantages of proxy signature and batch signature, which can also prevent the original signer from generating proxy batch signature, and the proxy signer can generate the batch signature of a set of messages at same time, each message can verify on its own. Experimental results show that, its efficiency and security is also better than the existing ones.
