| 摘 要： | 门限代理签名是代理签名与门限签名结合产生的签名体制,具有分配代理签名权力和分散代理密钥的优点.无证书密码体制既保持基于身份的密码体制不需要使用公钥证书的优点,又较好解决基于身份公钥体制所固有的密钥托管问题.文章将无证书签名方案和门限代理签名方案结合,提出一个新的无证书门限代理签名方案,新方案具有安全、高效的特性.

| Abstract: | Threshold proxy signature is a signature scheme which puts proxy signature and threshold signa-ture together.It has advantages of division of proxy powers and distributing the proxy key.Certificateless pub-lic key cryptography effectively solves the inherent key escrow problem in identity-based public key cryptog-raphy while keeps its certificate free property.This paper proposes a new certificateless threshold proxy signa-ture scheme putting the certificatless signature scheme and threshold proxy together.It is safe and efficient. |
