A communication system is provided with an information processing device and a management device capable of outputting predetermined data to the information processing device. The management device is provided with a challenge input device, an encryption device, and a combination data output device. The challenge input device inputs challenge data output by the information processing device. The encryption device creates combination data including the challenge data and the predetermined data, and encrypts the combination data in units of blocks. Each block has a unit data size. The encryption device creates the combination data such that at least one block of the combination data includes both at least a part of the challenge data and at least a part of the predetermined data. The combination data output device outputs the combination data encrypted by the encryption device to the information processing device. The information processing device is provided with a challenge output device, a challenge storage, a combination data input device, a decryption device, and a data utilizing device. The challenge output device outputs the challenge data to the management device. The challenge storage stores the challenge data output by the challenge output device. The combination data input device inputs the encrypted combination data output by the management device. The decryption device decrypts the encrypted combination data in units of the blocks. The data utilizing device compares the challenge data included in the combination data decrypted by the decryption device and the challenge data stored in the challenge storage, utilizes the predetermined data included in the combination data decrypted by the decryption device in a case where both challenge data are identical, and is prohibited from utilizing the predetermined data included in the combination data in a case where both challenge data are not identical.

A device management system that can easily manage devices on a network existing beyond a router. In the device management system, firstly, a management device transmits a packet to a probe device beyond a router. Then, the probe device broadcasts onto a network. Then, the device on the network transmits, by return, a reply-packet to the probe device. Then, the probe device determines whether the reply-packet is one received from the device that is to be managed, and transmits to the management device only the reply packet received from the device that is to be managed.

An information-processing apparatus which is capable of transmitting device identifiers of devices connected with LANs to terminals without using a broadcast command is provided. A server is connected with a World Area Network. A managing terminal and printers are connected with a LAN. The server receives a device identifier of the printer connected with any one of the LANs. The server receives an inquiry for a device identifier from a terminal connected with any one of the LANs. The server stores appended information, which is appended to the device identifier while the device identifier is transferred to the server, in a manner that the appended information is associated with the device identifier. The server transmits to the terminal the device identifier whose appended information as stored in a storage coincides with the appended information that is appended to the inquiry while the inquiry is transferred to the server. The managing terminal can obtain the device identifier of the printer connected with the same LAN as the managing terminal itself by transmitting the inquiry to the server.
