Ring signature is a promising technique to developed to authenticate information sharing in multi-party network. It enables an information proprietor to secretly confirm his information which can be put into the cloud space or analysis purpose. In this paper, we additionally improve the security of ring signature by giving forward security: If a secret key of any client has been compromised / hacked, all past produced signature that incorporate this client still stay substantial. This property is particularly vital to any substantial scale information sharing framework, as it is difficult to ask all information proprietors to re-verify their information regardless of whether a secret key of one single client has been compromised / hacked. We give a solid and effective instantiation of our plan, demonstrate its security and give a usage to demonstrate its reasonableness.
