<p>A common security key generation apparatus is employed to analyze encrypted data by using key data of a transmitter and a receiver. When exchanging keys between an initiator and a responder, the common security key generation apparatus creates security keys of the initiator and the responder, and public keys based on the security keys, thereby transmitting the public key of the initiator to the responder and the public key of the responder to the transmitter, simultaneously. A common security key of the responder is created from a public key of the responder received from the responder and the security key of the initiator created by the common security key generation apparatus, and a common security key of the initiator is created from a public key of the initiator received from the initiator and the security key of the responder created by the common security key generation apparatus. <IMAGE></p> |
