In Public key cryptography a message is sent after applying the digital signature and encryption techniques by the sender. These techniques are used so that the message properties such as confidentiality, integrity and unforgeability are maintained and the non-repudiation can be ensured at the receiving end. The digital signatures and encryption mechanisms can be combined to form a single logical step called Signcryption. In this paper a Signcryption scheme is suggested which is based on Elliptic Curve Cryptography (ECC) with an authentication technique of generating true random number from image for the authenticity of the valid message. The scheme provides additional security and authentication features which include the property of forward secrecy, public verifiability authenticity and counter steps. The proposed scheme provides better performance aspect for the security feature provided; compared to the traditional Signature-then-Encryption schemes based on ECC.
