The first contribution lies in the context of the STORK project. As a first step to the design of an integrated, uniform and secure European eID platform, a feasibility study was conducted and a small demonstrator was developed as a proof of concept. As a result of such task, several STORK deliverables were submitted along a contribution for the Porvoo Group regarding the current state of eID across Europe. This work also benefits the second contribution. Second, it is introduced a new middleware solution for the Portuguese Electronic Citizen Card. This middleware should subsume the actual and o cial version. Its novelty lies in its ability to process foreign (European) eID cards and adapts its provided support and services (including the User Interface) in conformity. The validity of the proposed platform was ensured and proved by several successful case studies that MULTICERT can use and develop.engCartão electrónicoIdentificação electrónica - PortugalIdentificação electrónica - CEMiddleware - SoftwareCertificação digitalmaster thesis
