Nowadays, email has become the most widely communication way in the daily life. By using identity-based encryption scheme, we propose a high efficient identity-based authenticated email protocol, which provide perfect forward secrecy. In contrast to previous email protocols, our scheme does not use PKI and so it avoids complex certificate and key management problems. And we prove that our scheme satisfies the security property of confidentiality assuming that the Computational Diffie-Hellman problem is hard. In addition, our scheme has low computation cost and little bandwidth demand which is suitable for mobile communication environment.
