The collaboration work between the Stockholm University and DESY in Hamburg regarding the European XFEL is among other things aiming towards to provide access methods to the accelerator control system for the European XFEL project with the possibility of a secure and reliable access from remote places. The requested expansion of the control system has been designed as an extra layer for control and data transmissions integrated with systems for authentication and authorization. This makes it possible to have these remote access methods working side by side with more conventional access methods in the control system. This gives you the possibility to access the control system remotely with traditional, already in use rich clients implemented in Java and expanded with an extra layer for the remote communication or you can use other clients in the future, e.g. web applications. A key focus here is to implement these requirements and at the same time achieve good performance in a secure and reliable way.
