Research on real-time computing method of computer node identification in the field of scalable and verifiable distributed AI collaborative computing

Abstract

The invention relates to a node authentication method and system of a distributed AI collaborative computing system. The method comprises: a central server sends authentication instructions to each distributed node; each distributed node completes the corresponding real-time computing capability verification task according to the authentication instruction and sends a response message to the central server; the response message includes task completion time and node equipment information; the real-time computing capability verification task includes a real-time computing capability verification task and a real-time storage capability verification task; the central server receives the response message. If the time of receiving the response message exceeds the expected time, or the difference between the task completion time and the task completion time of the real node of the same device type completing the real-time computing capability verification task is greater than the preset threshold, the node is identified as a suspicious node; the central server sends authentication instructions to the suspicious node for many times and receives the response message returned by the suspicious node. If the time of receiving the response message exceeds the expected time or the difference between the task completion time and the task completion time of the real node of the same device type completing the real-time computing capability verification task is greater than the preset threshold, Then it is judged that the node is forged.
