Biometrics-Based Dynamic Authentication For Secure Services, Saif Mohammed Saeed Abdulla Al Aryani

Theses

This thesis proposes a secure authentication protocol against physical session hijacking attacks. In client/server technology, users establish sessions to access the services offered by the servers. However, using physical session hijacking attacks, malicious users may physically take control of ongoing sessions. Malicious users also can establish sessions with servers using stolen passwords. In both cases, the server will be communicating with the wrong user who pretends to be the real user. The goal of this authentication protocol is to continuously and dynamically ensure that during an ongoing session the current session’s user is himself the real person that is known …
