Abstract. The secure collaborative judicial workspace (SCJW) has to allow the actors to use a number of communication and scheduling instruments for managing and storing any kind of documentation, video and audio recordings, evidence, among different Judicial offices of different countries. In this scenario is very important to identify encoded application delivering those application services to guarantee secure communication, but at the same time it is important to not compromise privacy of information exchanged. In this paper we aim at identifying application flows encoded within SSH tunnels by relying on statistical feature of IP packets. This will enable SCJW network administrator to identify un-trusted applications without analyze traffic contents.
