Abstract
Using communication services is a common part of everyday life in a personal or business context. Communication services include Internet services like voice services, chat service, and web 2.0 technologies (wikis, blogs, etc), but other usage areas like home energy management and eMobility are will be increasingly tackled. Such communication services typically authenticate participants. For this identities of some kind are used to identify the communication peer to the user of a service or to the service itself. Calling line identification used in the Session Initiation Protocol (SIP) used for Voice over IP (VoIP) is just one example. Authentication and identification of eCar users for accounting during charging of the eCar is another example. Also, further mechanisms rely on identities, e.g., whitelists defining allowed communication peers. Trusted identities prevent identity…
