Delivery of a Certified E-mail Service over the Digital Terrestrial Television Platform

Abstract

At present, the electronic mail service is probably the most widespread and commonly used asynchronous way ofexchanging information among people, thanks to its immediacy and easiness of use. Information delivered through E-mail can be sensitive or confidential: ensuring the sender’s identity and providing privacy has become a vital step in stopping spam, fraud and even more serious crimes. To this aim, public entities have adopted Certified E-mail systems to manage secure interactions with citizens.Digital Terrestrial Television introduced new facilities in thetraditional broadcasting environment, and determined the transition of several Electronic based-services to Television basedservices. The availability of commercial Set Top Boxes equipped with network interfaces and smart card readers enables the provisioning of personalized interactive TV services, requiring user’s identification and authentication, that still represent open issues in the TV context. In this paper we discuss the challenges of a Certified E-mail service over Digital Terrestrial Television,and present the case study of the Italian Regione Marche, in which this service is under development to support the remote request of certificates issued by the public administration. In particular, our attention is devoted to user authentication and secure access to the administrative services, addressed through the use of a Regional Service Card, an interactive application, and a centralized authentication framework.
