PROBLEM TO BE SOLVED: To provide a method for authorization of service requests to service hosts within a network. SOLUTION: Communication within the network is performed based on a routing mechanism, according to which user terminals within the network are associated with routable network addresses. A service host (B) sends a nonce included in a request message (CReq) to the network address of a requesting user terminal (A). The user terminal (A) resends the nonce or a value inferable from the nonce by the service host (B) as well as by the user terminal (A) included in a response message (CRes) to the network address of the service host (B).
