| 摘 要： | 针对已有门限代理签名方案存在的安全及性能方面的问题，将双线性映射引入签名方案，并结合卡梅隆签名，提出了一种基于双线性映射的卡梅隆门限代理签名方案。该方案克服了已有方案的安全缺陷，同时满足了强安全门限代理签名方案应具备的所有安全属性，能抵御各种可能的攻击。

| Abstract: | Aiming to problems about security and performance exist in many proposed threshold proxy schemes.The bilinear pairings are introduced to signature scheme.A chameleon threshold proxy signature scheme based on bilinear pairings is presented combined with chamelen signature,which can resolve the security problems existing in many proposed scheme,furthermore,satisfy all security attributes with which the strongly-secure threshold proxy signature scheme should be provided,it can resist many different kinds of possible attacks. |

| Keywords: | threshold proxy signature bilinear pairings probability signature scheme original signer changing attack |
