New generations of Estonian eGovernment components

The developing of Estonian eGovernment components started approximately 15 years ago. In this article, we discuss our experience how the main components of Estonian eGovernment like public key infrastructure, data exchange layer and governmental portal have developed and changed within this period. Estonian ID-card is the best representative of our public key infrastructure technology. The project X-Road realizes the idea of connecting all government information systems over the Internet. The governmental portal is the largest eServices provider in Estonia. All these systems are quite different from the first versions that appeared at the beginning of the century.
