A directly public verifiable signcryption scheme is introduced in this paperthat provides the security attributes of message confidentiality,authentication, integrity, non-repudiation, unforgeability, and forward secrecyof message confidentiality. It provides the attribute of direct publicverifiability so anyone can verify the signcryption without any need for anysecret information from the corresponding participants. The proposed scheme isbased on elliptic curve cryptography and is so suitable for environments withresource constraints.
