Abstract

The electronics controller and electronic devices can securely share a common key and make an encrypted communication. A serial key of the electronic device controlled by the element to obtain a serial key 102 is obtained. A common key of the electronic device stored at the element to store a common key 103 is encrypted at the element to encrypt a common key 104 by a serial key, and is transmitted to the electronic device by the element to transmit an encrypted common key 106. A common key is shared by the electronics controller and electronic device. A control signal is encrypted by a shared common key, and is transmitted to the electronic device.
