- In 2005, Sun, Hsieh, and Hwang proposed two secure e-mail protocols with perfect forward secrecy. In the first protocol, the authors apply smart card and Diffie-Hellman key agreement scheme to achieve the perfect forward secrecy. However, due to it requires a smart card to store some parameters, it is not practical in the real world. Thus, the authors proposed another protocol without a smart card. However, the second protocol has a security flaw in providing perfect forward secrecy. In this paper, we shall not only point out the secure flaw in the second protocol but also propose an improvement scheme to overcome the security flaw.
