Providing Login and Wi-Fi Access Services With the eIDAS Network: A Practical Approach

The digital identity (or electronic identity) of a person is about being able to prove upon authentication who one is on the Internet, with a certain level of assurance, such as by means of some attributes obtained from a trustworthy Identity Provider. In Europe, the eIDAS Network allows the citizens to authenticate securely with their national credentials and to provide such personal attributes when getting access to Service Providers in a different European country. Although the eIDAS Network is more and more known, its integration with real operational services is still at an initial phase. This paper presents two eIDAS-enabled services, Login with eIDAS and Wi-Fi access with eIDAS , that we have designed, implemented, deployed, and validated at the Politecnico di Torino in Italy. The validation study involved several undergraduate students, who have run the above services with their authentication credentials and platforms and with minimal indications on their usage. The results indicate that the services were beneficial. Several advantages exist both for the users and for the Service Providers, such as resistance to some security attacks and the possibility to adopt the service without prior user registration ( e.g. for short meetings, or in public places). However, some students expressed doubts about exploiting their national eID for Wi-Fi access, mainly in connection with usability and privacy issues. We discuss also these concerns, along with advantages and disadvantages of the proposed services.
