Abstract
|
Identity Management (IdM) is a set of technologies to authenticate users and to manage associated user data in Information and Communication Technology (ICT) systems. Within the internet and within intranets IdM is applied to improve security and usability for users by reducing the number of authentication procedures (Single Sign-On) from a single device. Nowadays, users have multiple devices to consume services in the Internet or in intranets. Existing IdM systems do not sufficiently support users with multiple devices. This dissertation proposes a new system to extend IdM systems to support users with multiple devices. The designed system architecture is based on the collaboration of user's devices. It is evaluated with respect to security and usability. A prototypical implementation verifies the interoperability with an existing IdM system. The system design adheres to a new design methodology, which has been developed as part of this thesis, to consider security in all development phases.
