基于身份代理权可撤销的代理签名

代理签名体制中代理签名权的撤销问题至关重要,SONG等人提出一种可撤销代理权的代理签名方案。提出了一种新的基于身份的可撤销代理权的代理签名方案,原始签名者在发现代理签名者不诚实时,可以通过可信中心TA及时有效地撤销代理签名者的代理签名权,且在该方案中将用户个人信息作为身份标识,大大减少了密钥的存储和管理开销。

ID-Based Proxy Signature Scheme with Efficient Proxy Revocation

The proxy revocation is very significant in the proxy signature system,and SONG et al once proposed a proxy signature scheme with proxy revocation. In this paper,a new ID-Based proxy signature scheme with proxy revocation is presented. In this scheme,once the malicious proxy signer is found,the original signer can immediately revoke the signing power of the malicious proxy signer through the trusted authority. And with user＇s personal information as the ID identification, the cost of key storage and management is greatly reduced.
