SSL/TLS session-aware user authentication revisited
Man-in-the-middle (MITM) attacks pose a serious threat to SSL/TLS-based e-commerce applications, and there are only a few technologies available to mitigate the risks. In [OHB05], we introduced the notion of SSL/TLS session-aware user authentication to protect SSL/TLSbased e-commerce applications against MITM attacks, and we proposed an implementation based on impersonal authentication tokens. In this paper, we present a number of extensions and variations of SSL/TLS session-aware user authentication. More specifically, we address multiinstitution tokens, possibilities for changing the PIN, and possibilities for making several popular and widely deployed user authentication systems be SSL/TLS session-aware. Furthermore, we also investigate the technical feasibility and the security implications of software-based implementations of SSL/TLS session-aware user authentication. Keywords.
