摘　　要：跨域接入控制通过保证授权用户对目标进行合法接入来保护数据资源的安全,因此,设计基于区块链的无线网络跨域接入自动化控制系统,保障无线网络信息资源安全性。系统整体分为四个层次:设备层内的无线网络设备向机构层发送身份请求信息;机构层内的密钥生成单元负责生成密钥信息,身份管理单元采用基于安全仲裁的无线网络身份签名方案,结合密钥信息生成用户(无线网络设备)签名,并向区块链层提取接入请求;区块链层处理机构层用户接入请求,同时以用户属性与无线网络跨域接入策略实现用户跨域接入授权的控制,在允许接入条件下,利用设备层的移动通信等设备进行跨域数据交互;链外存储单元负责存储跨域接入控制过程中产生的域身份组信息等。测试结果显示该系统能够有效实现跨域接入控制目的,能够保障无线网络信息资源安全,区块链网络决策策略功能的TPS均值约为131,具有良好的可应用性。Cross domain access control protects the security of data resources by ensuring that authorized users have legitimate access to the target.Therefore,a blockchain based wireless network cross domain access automation control system is designed to ensure the security of wireless network information resources.The system is divided into four levels as a whole:wireless network devices within the device layer send identity request information to the institutional layer;The key generation unit within the institutional layer is responsible for generating key information,while the identity management unit adopts a wireless network identity signature scheme based on security arbitration,combined with key information to generate user(wireless network device)signatures,and extracts access requests from the blockchain layer;The blockchain layer processes user access requests at the institutional layer,while controlling user cross domain access authorization based on user attributes and wireless network cross domain access policies.Under allowed access conditions,cross domain data exchange is carried out using mobile communication devices at the device layer;Off chain storage units are responsible for storing domain identity group information generated during cross domain access control processes.The test results show that the system can effectively achieve cross domain access control and ensure the security of wireless network information resources.The average TPS of the blockchain network decision strategy function is about 131,which has good applicability.
