面向复杂电力网络拓扑的密钥动态活性保持方法
A Key Dynamic Activity Preservation Methodfor Complex Power Network Topologies
摘要
Abstract
In the context of intelligent transformation of new power systems,communication networks with multi-layer heterogeneous characteristics form a dynamic open topology.Communication between entities is mainly categorized into two main types:intra-domain communication and cross-domain communication,where intra-domain communication covers horizontal communication across multiple gateways as well as vertical communication;Cross-domain communication,on the other hand,encompasses a variety of scenarios,such as multi-level trans-encrypted communication and over-the-air communication.Multi-type network architecture poses a double challenge to key management system:on the one hand,it is necessary to construct a dynamic activity maintenance mechanism in the dimension of network security domain to deal with the key state migration time sequence;On the other hand,it is necessary to ensure that the key is highly available and alive to guarantee the uninterrupted operation of the business as well as the secure encryption and integrity of upstream and downstream business data.Aiming at the above problems,this paper proposes a key active state management model based on complex electric power communication network,which precisely regulates the key state transition process by constructing a key state transition mechanism and a state migration constraint matrix,realizes the efficient management of the key,and ensures that the key continues to maintain high efficiency and activity while guaranteeing the security and reliability in the scenarios of differentiated demands.Finally,the scientific and rationality of the proposed method in this paper in complex power network topology is verifiedby simulation.关键词
