UC secure signcryption protocol with public verifiability;

In the paper, a publicly verifiable protocol based on intractable problems of elliptic curves discrete log is proposed.

The new scheme enjoys desirable properties as follows: signature unforgeability,public verifiability and forward secrecy.
