WIRELESS COMMUNICATION SYSTEM, COMMUNICATION TERMINAL, SECURITY MANAGEMENT SERVER, DEVICE MANAGEMENT SERVER, AND WIRELESS COMMUNICATION METHOD THEREIN

摘要

Data is safely transmitted or received between an electronic device and a communication terminal. The electronic device having a wireless communication capability transmits data, which is encrypted using a predetermined cryptographic key, to the communication terminal, and decrypts data, which is transmitted from the communication terminal, using the predetermined cryptographic key. The communication terminal capable of wirelessly communicating with the electronic device transfers encrypted data to or from the electronic device, and requests a security management server to encrypt or decrypt data. The security management server encrypts or decrypts data, which is transmitted from the communication terminal, using the predetermined cryptographic key, and transmits the data to the communication terminal.

主权项

1. A wireless communication system comprising:
an electronic device having a short-range wireless communication capability; a communication terminal that performs the short-range wireless communication with the electronic device and operates the electronic device; and a security management server that is connected to a network and manages security of data which is transmitted or received between the electronic device and the communication terminal, wherein: the electronic device transmits data, which is encrypted using a predetermined cryptographic key, to the communication terminal through the short-range wireless communication, and decrypts data, which is transmitted from the communication terminal through the short-range wireless communication, using the predetermined cryptographic key; the security management server encrypts or decrypts data, which is transmitted from the communication terminal over the network, using the predetermined cryptographic key, and transmits the data to the communication terminal over the network; and the communication terminal transfers encrypted data to or from the electronic device through the short-range wireless communication, and requests the security management server to encrypt or decrypt data over the network.
