Any one of the respective terminal units becomes a parent terminal equipment, one or more other terminal units are made child terminal equipments and, in case where the information is transferred from the parent terminal equipment to each child terminal equipment, the parent terminal equipment sends to the host computer (1) an information demand data for specifying and commanding the information to be transferred and an information on an identification information and a sending order about the child terminal equipments becoming a transfer destination of the information. The host computer (1) applies an encryption processing with respect to the information demanded by the terminal equipment, sends the encrypted data to the parent terminal equipment and, on receiving a perusal demand data from the terminal unit in the LAN, performs an authentication based on the identification information, thereby sending a cryptanalysis data to a legitimate terminal unit.
