INFORMATION SUPPLY SYSTEM

摘要

PROBLEM TO BE SOLVED: To prevent the contents of a request from leaking by always ciphering the information supply service request passing on an external network. SOLUTION: A Web server 10 has an information supply part, a Web server- side network ciphering/decoding part and a Web server-side network communication part. The information supply part supplies information in accordance with the regular information supply service request from a client 20. The Web server- side network ciphering/decoding part ciphers/decodes information which is transmitted/received with an AC server 30. The Web server-side network communication part executes communication through an AC server-side network 3a. Thus, information passing on the network is always ciphered and access control on supply information and the leakage of a ciphered key add supply information can be prevented.
