2results about How to "Prevent impersonation attacks" patented technology

The invention discloses a zero-trust-based power distribution edge Internet of Things intelligent terminal multi-factor trust evaluation system. The system comprises a cloud server layer, an edge layer and an Internet of Things terminal layer, the cloud server layer serves as a data center, can interact with an edge Internet of Things proxy server in the edge layer through a communication network, provides services required by an edge Internet of Things proxy, and performs identity authentication on the edge Internet of Things proxy; the edge layer comprises one or more edge internet-of-things proxy servers, and a zero-trust engine is arranged in each edge internet-of-things proxy server; the Internet of Things terminal layer refers to an intelligent terminal accessed to the power distribution Internet of Things, a zero-trust client is deployed on the intelligent terminal, and the intelligent terminal can interact with an edge Internet of Things proxy server of a region where the intelligent terminal is located through the zero-trust client and submit an access request. The invention further discloses a zero-trust-based multi-factor trust evaluation method and application of the intelligent terminal of the power distribution edge Internet of Things.

The application discloses a tamper-proof business process verification method and system, and the patent verifies the hash value by abstracting the terminal request cloud update business process, the hash value is generated based on the hash abstract of the last change process and the business process information of this time change each time, and the terminal server feedback each time hash value is used as the next business process change to obtain the hash value. The legality of the business process change is verified, the legality, traceability, effectiveness and other characteristics of the business process update are verified, and the functions of preventing man-in-the-middle impersonation attacks and random tampering are achieved.
