A Modified Strong Proxy Signature Scheme For Privacy Protection
Now most of the proxy signature scheme cant protect original signers privacy efficiently. Based on the current situation, as we cryptanalyzes the existing digital proxy signature scheme for privacy protection in this paper, we find a lack of security in the former ones and put forward a new modified scheme, which resolves security problem in original scheme. The improvement is much more perfect and adaptable. The modified scheme can completely prevent the forgery attack by original signer in the process of proxy signature and resist all known attack.
