Embodiment Construction

[0036] Certain embodiments of the accompanying drawings of the present invention are described in more detail below.

[0037] according to figure 1 , the present invention is built on the basis of model checking technology, and the specific implementation mode is:

[0038] 1. Establish a state transition system and detection based on time automata for distributed network protocols

[0039] The detection method described in the present invention abstracts the smart grid distributed network protocol into a finite state machine migration system, divides the main body of the distributed network protocol into three parts: the client, the server and the device, and is the client of the distributed network protocol. The state transition system based on the time automata is respectively established on the terminal, the server and the device.

[0040] For distributed network protocol clients, timed automata are used to describe the state process of executing the protocol. When the c...

Abstract

The invention provides a distributed network protocol security detection method for a smart power grid. The method is that the distributed network protocol of the smart power grid is expressed by a state migration system composed of a timed automation machine; the conditions to be met by the distributed network protocol security of the smart power grid are expressed through a temporal logic formula; the distributed network protocol security is detected on the premise that no attacker appears; after introducing the attacker, the distributed network protocol safety is detected again. The method specifically comprises the steps of 1) building the state migration system based on the timed automation machine for the distributed network protocol, and detecting; 2) building an attacker model and detecting the distributed network protocol security; 3) building a detector model, improving the distributed network protocol security, and then detecting. With the adoption of the method, any security problem can be detected through the detector model, thus a user can continuously improve the protocol, and as a result, the security of the distributed network protocol of the smart power grid can be effectively improved.

Description

technical field [0001] The invention relates to a security detection method of a smart grid distributed network protocol, which mainly uses model inspection technology to solve the security detection problem of a smart grid distributed network protocol, and belongs to computer technology, smart grid, real-time technology, distributed system and verification technology cross-technical application areas. Background technique [0002] The smart grid is the future development direction of the power grid. It is based on advanced communication technology, sensor technology, and information technology, and uses information interaction between grid equipment as a means to achieve reliable, safe, economical, efficient, environmentally friendly and environmentally friendly grid operation. Use advanced modern power system for safety purpose. Based on the modern transmission and distribution network as the physical basis, the smart grid is built on an integrated and high-speed two-way ...
