Title:
DATA COMMUNICATION SYSTEM AND DATA COMMUNICATION METHOD
Document Type and Number:
Japanese Patent JP2015043535
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To perform data communication satisfying both low communication cost and high security.SOLUTION: In a data communication system, a terminal device 102 performs the encryption of collection data collected by a data collection unit, the generation of an encryption key and data division. After transmitting one of the divided data obtained by the division to a backbone device 101 using a high security or a continuously usable data transmitter unit X, the terminal device 102 transmits another divided data obtained by the division and the encryption key to the backbone device 101 using a data transmitter unit Y of low communication cost. The backbone device 101 tries to receive both divided data and the encryption key using a data receiver unit Y. When a connectable data determination unit determines the successful reception of both divided data and the encryption key, both divided data are connected and decrypted using the encryption key.
