Abstract

Secure user authentication, provision of identity attributes, privacy preservation, and cross-border applicability are key requirements of security and privacy sensitive ICT based services. The EU large scale pilot STORK provides a European cross-border authentication framework that satisfies these requirements by establishing interoperability between existing national eID infrastructures. To allow for privacy preservation, the developed framework supports the provision of partial identity information and pseudonymization. In this paper we present the pilot application SaferChat that has been developed to evaluate and demonstrate the functionality of the STORK authentication framework. SaferChat makes use of age claim based authentication mechanisms that allow for an online environment where kids and teenagers are able to communicate with their peers in a safe way. We first identify relevant prerequisites for the SaferChat pilot application and then give an introduction to the basic architecture of the STORK authentication framework. We finally show how this framework has been integrated into the SaferChat pilot application to meet the identified requirements and to implement a secure and privacy preserving cross-border user authentication mechanism.
