A directly public verifiable signcryption scheme is introduced in this paper that provides the security attributes of message confidentiality, authentication, integrity, non-repudiation, unforgeability, and forward secrecy of message confidentiality. It provides the attribute of direct public verifiability so anyone can verify the signcryption without any need for any secret information from the corresponding participants. The proposed scheme is based on elliptic curve cryptography and is so suitable for environments with resource constraints.
Note: As originally published there is an error in the document's author byline. The name of the second author was listed as "Ali Asghar Beheshti Shirazi." The author wishes citations be credited to "Beheshti, A." The change is noted in Xplore's metadata but the PDF remains unchanged.
