A Linkable Anonymous Signcryption Scheme
Shiming Li · Journal of Southwest University · 2012
A new linkable anonymous signcryption scheme based on the discrete logarithm problem of Z * p is proposed and its security is analyzed and proved in this paper.The scheme combines symmetrical encryption with ring signature,thus making it more efficient than the traditional method(signature followed by encryption).While maintaining the security characteristics of common signcryption schemes,this scheme has the characteristics of linkability and unconditional anonymity.Therefore,the scheme can effectively protect the privacy of the user and hence has good application prospects.
