COMMUNICATION INTERFACE DEVICE, CIPHER COMMUNICATION METHOD, IMAGE-FORMING DEVICE, PROGRAM, AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To facilitate the setting of key information in each device when performing the radio communication of data between the devices. SOLUTION: A communication interface device for performing encryption communication comprises: a detector for detecting a communication request of information on file data; a key generator for generating key information for performing the encryption communication; a first communication section for communicating the key information generated at the key generator by other communication interface devices and a first communication system according to detection by the detection section; and a second communication section for making cipher communication to the file data requested by other communication interface devices in a second communication system by the key information generated at the key generation section.
