Context-Aware Multi-Factor Authentication
Authentication systems, as available today, are inappropriate for the requirements of ubiquitous and heterogeneous large scale distributed systems, applications and services. Some important limitations are: (i) use of weak or rigid authentication factors as principal’s identity proofs, (ii) non flexibility to combine different authentication modes for dynamic and context-aware interaction criteria, (iii) non extensible models to integrate new or emergent pervasive authentication factors and (iv) difficulty to manage the coexistence of multi-modal and multi-factor authentication proofs in a unified single sign-on solution. The objective planned for this dissertation is the design, implementation and experimental evaluation of a platform supporting multi-factor and multi-modal authentication services, as a contribution to overcome the above limitations. The devised platform will provide a uniform and flexible authentication base for multi-factor authentication requirements and context-aware authentication modes for ubiquitous applications and services. The main contribution will be focused on the design and implementation of an extensible authentication framework model, integrating classic as well as new pervasive authentication factors that can be composed for different context-aware dynamic requirements. Flexibility criteria will be addressed by the establishment of a unified authentication back-end, supporting authentication modes as defined processes and rules expressed in a SAML based declarative markup language to be designed. The authentication base will support an extended single sign-on system that can be dynamically tailored for multi-factor authentication rules and policies supporting multi-device and multi-modal ubiquitous interaction needs.
