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: ...

Abstract

The invention relates to an information safety algorithm based on an energy information gateway in a smart power grid, ad an introduced safety mechanism is divided into an identity verification process, an encryption information message format and an information communication process according to a connecting flow path. Based on an RSA encryption algorithm, an advanced encryption standard (AES), digital signature and other technologies, the safety mechanism with instruction information transmission confidentiality, integrity and non-repudiation is achieved. By using the respective advantages of the three technologies, the condition that a smart electricity using network transmits sensitive information in a public network is combined, the situations of identify forging, data stealing, repeated attack sending and the like are considered sufficiently, and a bi-directional identity verification and safe instruction transmission mechanism is provided, so that the data attacks are effectively prevented, and traceability of instructions is ensured. A practicable and reliable solution is provided for safe data transmission in the demand response and home automation technology in China.

Description

technical field [0001] The invention relates to an information security algorithm based on an energy information gateway in a smart grid, and belongs to the technical field of the smart grid. Background technique [0002] In recent years, my country has continuously created new peaks of electricity consumption, and the difference between peaks and valleys has become larger and larger, which has brought certain difficulties to the operation of the power system. Power demand response puts forward new ideas to solve these problems. Smart electricity network is a form of demand response, which is a network formed by interconnecting various electrical appliances on the user side through energy information gateways. Based on this network, on the one hand, the monitoring and control of electrical equipment can be realized, and on this basis, the status of electrical appliances can be sensed, so as to realize the safe, healthy, comfortable, and energy-saving operation of the elect...
