摘要/Abstract

摘要： 基站动环监控系统通过将基站智能监控单元构建在底层被监控的智能和非智能设备之上,实现全网基站动环信息的监控、实时告警等功能。因此,动环监控系统的稳定是安全运行的前提。但随着基站数量的增加,现阶段中心服务器架构模式下的系统会显现出负载增加、流量过载等问题,且多对一的模式下容易出现DoS攻击、数据泄露等安全问题;另外,在多用户模式下,现有的系统模式无法达到对细粒度访问权限的控制。针对上述问题,结合区块链技术在分布式架构上独特的优势,文中提出一种基于改进型PBFT共识算法的双区块链基站动环监控系统架构,来解决现有动环监控系统中心化、安全、扩展等问题。具体地,该系统是一种层次型架构的信息系统,且各层次各维护一条区块链,是一个多节点共同维护与共享的双链区块链系统。其中,一条以联盟链的形式负责跨域信息的流转和权限的控制,另一条以私有链的形式负责基站设备访问权限的控制以及基站事务信息的流转。同时,基于PKI系统和密钥管理系统的支持,以及改进型区块头对权限信息的存储,达到对设备的细粒度访问权限的控制。最后,定性分析的结果表明了,相较于现有的传统动环监控系统,文中系统具有多中心服务、抗DoS攻击、基于用户的细粒度权限管理、信息的加密完备程度高和扩展性好等特点。

Abstract: The power and environment monitoring system of base station realizes the functions of the whole network base station power and environment monitoring and real-time alarm by constructing the base station intelligent monitoring unit on the underlying intelligent and non-intelligent devices.Therefore,the stability and safe operation of the po-wer and environment monitoring system is a prerequisite.However,as the number of base stations increases,the system in the central server architecture mode will show problems such as increased load and traffic overload,and the many-to-one mode is prone to DoS.Security issues such as attacks and data breaches.In addition,in multi-user mode,the existing system mode cannot achieve fine-grained access control.Aiming at the above problems,combined with the unique advantages of blockchain technology in distributed architecture,this paper proposed a double blockchain power and environment monitoring system of base station architecture based on improved PBFT consensus algorithm to solve the centralization,security,expansion and other.of the existing system problems.Specifically,the system is a hierarchical architecture 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.And achieves fine-grained access control of the device through PKI system and the key management system,and the improves block header to store the permission information.Finally,the results show that 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.
