| Popis: | The mine Internet of things has the characteristics of large-scale and massive data transmission. These characteristics make the traditional network security and privacy protection methods unable to guarantee the traceability and reliability of key data. The main security risks of mine Internet of things are lack of data transmission traceability and credibility guarantee mechanism, lack of comprehensive signature verification guarantee mechanism of system equipment, and lack of security carrier deployment in system architecture. It is pointed out that blockchain technology can solve the above problems. The key technologies such as blockchain structure, encryption algorithm and consensus mechanism of mine Internet of things are introduced. This paper proposes a blockchain mechanism of mine Internet of things. The edge layer with edge computing power is added between the perception layer and the transmission layer of the mine Internet of things. The security carrier carrying the core functions of the blockchain is deployed. Thus the deployment architecture of the mine Internet of things blockchain is built. The data transmission process under the blockchain mechanism of the mine Internet of things is designed. The asymmetric encryption technology is adopted to ensure the security of data transmission. In the application layer of the Internet of things in mines, the data chain management platform is adopted to realize the functions of key data uplink, data traceability and distributed certificate storage. The blockchain mechanism of mine Internet of things can improve the information security guarantee capability and security level of mine Internet of things. The mechanism can make mine Internet of things to meet the expansion requirements in GB/T 22239-2019 Information security technology-Baseline for classified protection of cybersecurity, and reduce the demand for centralized operation and maintenance. |
