Research into initiatives worldwide shows that although some of the legal and organizational barriers for the adoption of new technologies in e-government have been lifted, there are still not many implementations of actual e-government services that have been designed based on a common and systematic approach. The most prevailing requirements for e-government services, interoperability and security, pose major challenges to e-government architects and it is now being slowly understood that Web Services in combination with Public Key Infrastructures may provide the necessary solutions. In this context, this paper presents three innovative e-government services based on these technologies, fo-cusing on their security and interoperability aspects. The goal of the paper is to demonstrate the services’ specifications and use cases so that they may act as ex-amples for further research and development.
