A New Certificateless Undeniable Signature
Qunshan Chen · Journal of Zhangzhou Normal University · 2009
CL-PKC is a kind of public-key cryptosystem,which was proposed recently.It preserves the advantages of non public-key certificate and also has solved the key escrow problem in the ID-PKC.Many people are highly concerned about the design method of safe and efficient signature scheme in the certificateless system.In this paper,we construct a new certificateless undeniable signature by using bilinear pairings and zero-knowledge proof protocol.
