A Bluetooth mesh distributed blockchain data authorization encryption method

Abstract

The invention discloses a Bluetooth Mesh-based distributed block chain data authorization encryption method, which comprises the following steps: establishing its own data layer, network layer, consensus layer, contract layer and application layer on each node; performing data encryption At the same time, the data list and encryption algorithm are established in the data layer; the consensus algorithm in the Bluetooth Mesh network is established in the consensus layer; the authorization contract of the Bluetooth Mesh node is established in the contract layer to determine that each new node is newly added to the network. Or the information contract rules when exiting the network, the entire network of the present invention uses distributed encryption to complete the decentralization of the network, a block chain structure with high security and stability, and ensures the security of data in the entire network. Reliability and non-reproducibility. Bluetooth Mesh is currently mostly used in smart homes and smart cities. Using distributed authorization and encryption can ensure the non-reproducibility of each node and provide a unified platform for information traceability.

Description

technical field [0001] The invention relates to an encryption method, in particular to a Bluetooth Mesh distributed block chain data authorization encryption method. Background technique [0002] Since the birth of the first computer, after decades of rapid development, information technology has entered all aspects of our lives and is constantly changing our lives. We have entered an information age of information explosion, and a large amount of information relies on Traditional methods are difficult to achieve effective storage and transmission, so the development of information technology based on computer technology and network technology is particularly important. [0003] As an open specification for short-distance wireless data and voice communication, Bluetooth works in the free frequency band of 2.4GHz ISM, adopts fast frequency hopping spread spectrum technology, and has the advantages of fast communication speed, low power consumption, low cost, strong anti-inter...

Problems solved by technology

[0003] As an open specification for short-distance wireless data and voice communication, Bluetooth works in the free frequency band of 2.4GHz ISM, adopts fast frequency hopping spread spectrum technology, and has the advantages of fast communication speed, low power consumption, low cost, strong anti-interference, etc. Advantages, so it is widely used in various fields of life. However, because the technology uses wireless transmission, this may cause user data to be stolen by illegal users during transmission. The fast frequency hopping technology adopted by Bluetooth can only solve the system problem. Related interference problems caused by internal and external devices cannot be effectively discovered and accessed by illegal users. In the process of using Bluetooth Mesh, higher requirements are put forward for the security and privacy of each node. Based on The characteristics of Mesh distribution can use blockchain technology to encrypt system data
