An Unconditionally Anonymous Signcryption Algorithm Based on Elliptic Curves
Qing Cai · Journal of Henan University of Science & Technology · 2006
Based on the ideas of ECDLP and anonymous signature,an unconditionally anonymous signcription algorithm is proposed and its security proof is given.While satisfying all the security properties proposed in previous signcription schemes,the new scheme provides a new desired security property,complete-anonymity based on elliptic curve group signature,which makes the privacy of users protected to the largest extent.With all these features,this scheme can be applied on many special occasions,for example,in electronic cash and anonymity authentication.
