The basic concepts for the MeDoc service have been identified in a requirements analysis phase. This paper describes the security requirements and their implementation within the MeDoc prototype.

The MeDoc billing facilities imply the implementation of security mechanisms into the MeDoc service. Therefore security tools and implementations of cryptographic algorithms have been evaluated as to their suitability for the MeDoc service. Communication channels are now secured by transparent encryption mechanisms based on SSL. The prototype admits only registered users to the MeDoc library. The users are authenticated via password and can be charged via accounts.
