Forward Secure Designated Verifier Proxy Signature Scheme
摘要
Abstract
To deal with the key exposure problem in the designated verifier proxy signature,a forward secure designated verifier proxy signature scheme is proposed.The forward-secure thought is integrated into the new scheme in which the whole validity time is divided into T time periods,the public key always stays fixed while the private key updates as time goes.Experimental results show that the new scheme not only has some degree of improvement in terms of efficiency,but also realizes that even if the current proxy signer's key is exposed,the adversary can not succeed in forging the valid proxy signature pertaining to the past which can effectively reduce the damage of key exposure.关键词
