一种前向安全的无证书代理盲签名方案
Forward secure certificateless proxy blind signature scheme
摘要
Abstract
In order to solve the key exposure problem, a forward secure certificateless proxy blind signature scheme is proposed.This new scheme is forward secure by updating secret key frequently.When the proxy signature secret key is stolen, the former proxy blind signature still is available.And then it can reduce the loss,which is caused by the key exposure to a great extent.Based on certificateless public cryptosystem,it also overcames the problem of the certificate management in the certificate-based public key cryptosystem and the inherent key escrow problem in the identity-based public key cryptosystem.关键词
