Embodiment
[0039] The energy information gateway is used as the access point of the client network, and needs to communicate frequently with the demand response center and the client, so as to realize the remote control of home appliances and the demand response of loads. Since all messages are transmitted through the Internet, the communication security of the gateway is an important factor that must be considered in practical applications. According to the characteristics of the public network, the embodiment of the present invention divides the security mechanism introduced in the present invention into three parts: the identity authentication process, the encrypted message message format and the message communication process according to the connection flow. figure 1 It is a step diagram of the identity authentication steps of the gateway and the client in the embodiment of the present invention, which are introduced respectively below:
[0040] (A) Identity authentication process: ...
