A Signature Scheme with Message Recovery
Yan Shan-jun · Journal of University of Jinan · 2010
In view of message recovery not being allowed by ElGamal,a signature scheme with message recovery is proposed on the basis of analyzing the application of ElGamal signature scheme.Its security is based on the difficulty of solving discrete logarithm in finite field and quadratic residue on some special conditions.The processes of signature,authentication,encryption and decryption are simultaneously completed in communication protocols.The scheme has high security and can be easily carried out.
