Key distribution method for data communication based on block chain

Abstract

The embodiment of the invention discloses a secret key distribution method for data communication based on a block chain, and the method comprises the steps that a user T in a user service system reads a random secret key generation factor A from a block chain system, and then generates a secret key B through the random secret key generation factor A; the user T uses B or a part of B to calculatea key X1; repeating the steps S100 and S200 by a user T1 in the user service system to generate a key B1 calculation and a key X2; the user in the user service system converts the secret key X1 and the secret key X2 into two-dimensional codes and then sends the two-dimensional codes to the user T and the user T1 respectively; the user T analyzes the received two-dimensional code of the X1 and calculates Y; and the user T1 calculates the two-dimensional code of the X2, calculates Y1, and uses Y = Y1 as a session key to encrypt communication, thereby solving the problem of high operation load pressure of the existing server, and avoiding the problem of potential safety hazard caused by overhigh server pressure or DDoS external attack.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of Internet communication, in particular to a key distribution method for data communication based on blockchain. Background technique [0002] Various business data of the power distribution communication network, such as electricity meter data, terminal ledger data, status data, etc., may be collected by different business systems, resulting in the existence of the same type of data being collected multiple times by multiple business systems, wasting network communication resources, data Collection efficiency is not high. Using blockchain technology to build a power distribution communication data sharing platform will facilitate the sharing and utilization of data. Through this data sharing platform, the data is only collected once, and after processing, it is stored in the data sharing platform, and then the data is provided to various business systems through the data sharing ...

AI Technical Summary

Problems solved by technology

[0008] To this end, the embodiment of the present invention provides a key distribution method based on blockchain data communication. By introducing blockchain technology, the randomness required for key generation is completed, and at the same time, two-dimensional codes are used to transmit key distribution information, and interactive The number of times is small, and the configuration of the key distribution strategy is flexible, which solves the problem of heavy load pressure on the existing server and avoids potential safety hazards caused by excessive server pressure or external DDoS attacks
