An elliptic curve based signcryption scheme is presented in this paper. This scheme not only provides message confidentiality, non-repudiation, integrity and un-forgebility but also provides forward secrecy and encrypted message authentication. A judge can verify the sender’s signature on signcrypted message without decrypting message and take any help from sender. If the private key of the sender is divulged inattentively, it does not affect the confidentiality of the previous stored messages. Elliptic curves are used for their key size, security and bandwidth advantage .The proposed scheme can be applied to mobile communication environment due to low computational and communication cost.
