abstract: |
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. |
