| 摘 要： | 针对椭圆曲线离散对数问题的困难性提出一个具备快速撤销功能的代理签名方案.该方案引入一个安全中介SEM,生成部分代理签名,再由指定代理签名人生成完整的代理签名.代理签名人只有与SEM合作才能生成有效的签名,使得方案具有快速撤销的功能.

| Abstract: | Based on the difficulty of the elliptic curves discrete logarithm problem,a new proxy signature scheme withfast revocation was proposed,and a security mediator（SEM） was introduced in the scheme to generate partial proxy signatures.Then by a designated proxy signer generated the complete proxy signature.A proxy signer must cooperate with the SEM to generate a valid proxy signature,which made the new scheme have an effective and efficient proxy revocation. |
