ENCRYPTION COMMUNICATION METHOD WITH COMPUTER SYSTEM, AND COMMUNICATION SYSTEM

摘要

An encryption communication method with a computer system, and a communication system thereof are provided to reduce a load of a management server by enabling encryption communication without passing through the management server after settling an encryption communication path between a terminal device and a blade computer, and reinforce security by enabling encrypting communication through a communication path between the terminal and the blade computer including a network in an organization. One of terminal devices connects to a management server(12) connected to an entrance of a network(16) in an organization. The terminal device and the management server execute mutual authorization. The terminal device and the management server hold an encryption key in common and settles an encryption communication path between the terminal device and the management server. The management server selects a blade computer to become a communication partner of the terminal device, referring to a blade computer use state table. The blade computer settles an encryption communication path between the blade computer and the management server. The terminal device transmits a request for connection to the blade computer to the management server. The management server creates an encryption key for encryption communication between the terminal device and the blade computer. The management server transmits the connection request and the encryption key to the blade computer through the encryption communication path. The blade computer transmits the result of possibility of connection to the management server. If the terminal device is connectable to the blade computer, the management server notifies the possible connection to the terminal device and transmits the encryption key to the terminal device. An encryption communication path is settled between the terminal device and the blade computer for secure communication.
