Research And Application Of Access Control Of Base Station System Based On Blockchain Technology

The base station system's monitoring of the power and environment information and the real-time control of various intelligent devices of the base station are important guarantees for the smooth operation of the base station.No matter from the aspect of operation and maintenance or the management of base station facilities,it will a lot of the base station.The traditional base station system mostly adopts the centralized architecture service mode.In this mode,with the increase of the number of base stations,the center server will face the problems of traffic overload,Dos attack,scalability reduction,and so on,which has become the difficulty of the later base station system scale development.And in this mode,it is easy to cause a single point of failure due to the central service mode,which causes the risk of downtime of the entire system.In addition,with the complex use of base station functions(more and more equipment Shared by multiple operators and each operation and maintenance company),the base station management system cannot realize fine-grained access control at this stage,resulting in information leakage and other risks.Blockchain is a technology that uses modern cryptography as the underlying technology,and uses corresponding consensus algorithms to make block data consistent in a distributed environment.Firstly,the data is managed by multiple parties,which avoids the traditional central communication mode,and the data on the chain cannot be tampered with.Secondly,the public key system is the basis of communication in the blockchain system,which makes it possible to construct the original security of data and access control of communication entities.Based on the research of block chain technology and the potential of blockchain in distributed communication management,this paper explores the access control technology of blockchain in IoT devices,and further studies the problems existing in the traditional base station system.This paper proposes a dynamic power and environment information monitoring system for base stations based on a blockchain technology.It is a hierarchical architecture dual-blockchain structure information system,and each layer maintains a blockchain.the system is a dual-chain blockchain system that is maintained and shared by multiple nodes.One is responsible for the flow of cross-domain information in the form of a league chain,and the control of the authority.the other is responsible for the access control of the base station device and the flow of the base station transaction information in the form of a private chain.Achieves fine-grained access control of the device through PKI system,and the improved block header to store the permission information.Compared with the existing traditional system,the system of this paper proposed has certain advantages of multi-center service,anti-DoS attack,user-based fine-grained rights management,high degree of information encryption and good scalability through the qualitative analysis.Design and implement the base station privilege management system based on the blockchain technology.The system is based on IBM's Hyperledger Fabric,and the underlying cryptography suite of the system and business development Fabric-SDK has been retrofitted(SM2,3,4)to meet the requirements of national cryptography laws.On this basis,the base station privilege management system is analyzed and designed,and then developed and implemented.Finally,the main function of the system is tested.In summary,the feasibility of the application of the blockchain in the access control management of the base station system can be proved to a certain extent.The application prospect of the blockchain in the entire field of IoT management is also explained.
