In this paper, we address the key issues of trust, identity management and privacy, within the context of a modern, secure, Public Key Infrastructure- (PKI-) based e-government model. Firstly, we review the basic concepts, standards, methodological tools, critical success factors and international experience for designing and implementing PKI-based secure electronic services. We build on this by presenting a case study of a contextualised technology and process solution, namely the SYZEFXIS-PKI case, a nation-wide ongoing initiative aimed to provide a modern ICT infrastructure for the Greek Public Administration (GPA). Our goal is to communicate lessons learnt from the development, implementation and delivery of a national PKI-based environment, its repercussions and the critical success factors for its widespread use and effectiveness, as a major step towards the realisation of a secure e-governance model in Greece. Finally, we discuss the new modern vision of trust, identity management and privacy in the context of electronic governance and we postulate on future developments.
