摘　　要：在研究无网络状态下的定时约定机制和镜像同步运算获得密匙的基础上,提出了基于密码控制、非实时虚拟通信和按约定计算密匙的逻辑控制方法,能够很好地适用于智能锁或开关在无实时通信网覆盖下的动态认证以及开关工作。利用具有约定运算能力的智能终端,建立了一种无实时通信网络下的"密控网",既可作为物联网技术在无通信覆盖情况下的有益补充,也可作为固定地点的远端物件按计算次序移交管理权或使用权。通过采用终端的运算能力代替对远端的通信能力,而无须构建后台通信网络以及等候期的通信费用支出。On the basis of researching the timing agreement mechanism and mirror synchronization operation to obtain keys under the condition of no network,a logic control method was proposed based on cryptography control,non-real-time virtual communication and computing keys according to agreement,which could be well applied to dynamic authentication and switch operation of intelligent locks or switches without real-time communication network coverage.By using the intelligent terminal with the ability of agreed operation,a kind of"control network of cryptography"without real-time communication network was established,which could be used as a useful supplement to the IoT technology without communication coverage,as well as a remote object in a fixed location to transfer the right of management or use according to the order of calculation.By using the computing power of the terminal instead of the communication power of the remote end,without the need to build a backstage communication network and the communication expenses during the waiting period.
