Embodiment

[0047] Such as Figure 5 As shown, this embodiment provides an information sensitivity-aware adaptive security routing method for power-sensitive information, including, in step S10 , constructing a node next-hop wavefront according to the hop count of the shortest path from each node to the current node.

[0048] Specifically, for the convenience of explanation and description of the subsequent embodiments, the following definitions are given:

[0049] Definition 1: N represents the set of all nodes in the power communication network.

[0050] Definition 2: d(i, j) represents the shortest path distance between network nodes i and j.

[0051] Definition 3: N k (i) is called the k-hop next-hop wave surface of node i, which means the set of nodes whose shortest path distance from node i is k hops, defined as N k (i)={j|d(i,j)=k,j∈N};

[0052] Definition 4: N(i) represents the set of all next-hop wavefronts of node i, defined as

[0053] N(i)=N 1 (i)∪N 2 (i)∪…∪N k (i), k≥1 ...

Abstract

The invention discloses a power sensitive information adaptive security routing method for information sensitivity perception, relates to the field of power communication network security routing, and aims to reduce security risks existing in a transmission process of sensitive data of smart grid service application. According to the technical scheme, the method is characterized by comprising the following steps of: constructing a node next-hop wave surface according to the shortest path hop count from each node to a current node; according to the node next-hop wave surface, generating a feasible next-hop node set; calculating a node priority selection probability in the feasible next-hop node set; constructing a sensitive information virtual transmission path; and constructing a physical transmission path corresponding to the virtual transmission path according to a shortest path method. According to the method, a secure transmission guarantee scheme can be specifically designed for sensitive data in different service scenes, and the security risk of the sensitive information of the intelligent power grid service in the transmission process is reduced.

Description

technical field [0001] The invention relates to the field of safe routing of electric power communication networks, and more specifically, relates to an adaptive safe routing method for power sensitive information with information sensitivity awareness. Background technique [0002] The power industry is an important basic industry of the national economy, and the normal operation of the power system will have an important impact on the national economy and people's livelihood. The power communication network is an important infrastructure that provides protection for the power industry, and the security of various business-sensitive data in the power communication network is the top priority to ensure the normal operation of the power system. [0003] At present, the power communication network often adopts service routing algorithms based on Availability-Aware Routing (AAR) and load balancing (Load Balancing, LB). Although the AAR algorithm can improve the availability of...
