A user support system for cryptographic communication includes a key storage for storing keys used for deciphering, a deciphering part for deciphering an enciphered communication text into a deciphered communication text using a key, and a controller for starting the deciphering part only when an input communication text is the enciphered communication text and for supplying the key that is necessary for the deciphering in the deciphering part by retrieving the key from the key storage.

A computer provided with a routing information collecting unit which collects the dynamic routing information flowing in the network. The collected routing information is set in the routing table as static routing information by a setting unit. The routing unit performs the routing referring to the routing table. Further, it is possible to provide an information collection timing determining unit or an information collection completion determining unit so as to determine the timing of the collection of the routing information or the completion of the collection of the information. Further, it is possible to provide an optimum route discriminating unit and a default generating unit to determine the optimum gateway and to generate the default routing information. By this, static routing information can be set automatically without human intervention and flexibly.
