Management method and system of electric power Internet-of-Things terminal layer equipment secret key and storage medium

Abstract

The invention discloses a management method and system for an electric power Internet-of-Things terminal layer equipment secret key and a storage medium. The method comprises the following steps: initializing a secret key; using the terminal layer equipment as a node for initialization, and completing regional key initialization; generating a key pool; randomly numbering all nodes in the region, and randomly sorting the numbers by adopting a Hamilton algorithm; according to the random sorting of the node numbers in the region, selecting the sub-keys of the corresponding nodes to construct a complete region key, and collecting all the region keys to obtain a key pool; key negotiation; before the two nodes carry out encrypted data communication, randomly selecting sub-keys of the corresponding nodes from the key pool, carrying out mutual verification on the sub-keys of the two communication parties, and after identity information in the sub-keys is verified to be correct, calculating a session key through key parameters; and performing session key negotiation based on the session key, if the negotiation succeeds, sending a communication identifier by the two parties, opening the session, and starting data communication encrypted by the session key.

Description

technical field [0001] The present invention relates to the technical field of smart grid security, in particular to a management method, system and storage medium for a device key of an electric power Internet of Things terminal layer. Background technique [0002] With the continuous development of science and technology, the concept of ubiquitous power Internet of Things has entered people's field of vision. Ubiquitous Electric Internet of Things (UEIOT; Ubiquitous Electric Internet of Things) is to fully apply modern information technology such as mobile Internet and artificial intelligence and advanced communication technology around all aspects of the power system to realize the interconnection of all things and human-computer interaction in all aspects of the power system. An intelligent service system with comprehensive status awareness, efficient information processing, and convenient and flexible applications. Due to the massive number of terminals, nodes and ad h...
