Wei Cai-xi · Journal of Xinyu University · 2014
Aiming at the leakage of key of certificateless signature,this paper puts forward a new forward security certificateless signature scheme. This scheme is to regularly renew the clients' secret value to improve the security,and at the same time keep the characteristics of public key of the KGC document generation clients to avoid the possibility of substitution of public key by attack in the dishonest KGC document. The analysis of the security shows that the technology has good forward security and can effectively distinguish the dishonest behaviour of KGC document and prevent the possibility of substitution of public key by attack under the dishonest KGC document.
