This document is focused on explain how LEPS has solved the problem of eIDAS authentication and service integration in a mobile environment, following and adapting the guidelines of the project, which are:
• Improved online service and customer experience offering a mobile solution adapted to the new market;
• Substantial savings through the design of reusable and generic components;
• Data quality as the key attributes related to identity that are transported cross-border are certified by official MS eIDAS node and obtained from authoritative sources;
• Following the eIDAS Regulation  that provides the needed legal certainty and common legal basis for Member States to recognise and accept eID means issued in other Member States.
With this aim, it is necessary the development of a user mobile interface for authentication-attributes delivery management. This task is mainly in charge of the Spanish members of LEPS Consortium with University of Murcia (UMU) being the responsible partner for the development of the mobile eID application. In Greece, University of the Aegean (UAEGEAN) works with Hellenic Ministry of Administrative Reconstruction (HMIAR) and National Technical University of Athens (NTUA) to make all the necessary modifications of the Greek eIDAS node to support mobile ID enable citizen/customer authentication. They provide also support to the two Greek private companies participating in the LEPS Consortium the Hellenic Post S.A. (ELTA) and the Athens Stock Exchange S.A. (ATHEX) to update their infrastructures, so to interconnect with LEPS mobile eID app.
