E-mail plays an important role in mankind communication. It is essential to provide security solutions for the secure transmission of email. The currently used protocols such as PGP and S/MIME are based on public key cryptography that involves huge computational costs due to key generation, key exchange and encryption. In this paper, an elliptic curve based signcryption scheme is introduced that provides several security attributes such as confidentiality, authentication, integrity, non-repudiation, and forward secrecy for electronic mails.
