    Modeling and verifying based on timed automata of Internet of things gateway security system by Guoqing WANG, Lei ZHUANG, Ruimin WANG, Yu SONG, Kunli ZHANG

    Published 2018-03-01
    “…The Internet of things (IoT) is a multiple heterogeneous network,and its perception layer is often faced with various security threats.As the bridge between the perception layer and the network layer,the IoT gateway should have the security management function to prevent the security issue from spreading to the upper layer.According to the current security deficiencies in IoT gateway,a universal IoT gateway security system was proposed based on the IoT gateway middleware technology.Various security protocols or algorithms can be embedded in IoT gateway security system,and the modeling and analysis can help the design and implementation of IoT gateway.The formal modeling and verification of the IoT gateway security system was performed by timed automata.The results show that the IoT gateway security system satisfies the security properties of confidentiality,availability,authenticity,robustness,integrity and freshness.…”

    Control research and application of conventional operations without real-time networks by Zhengfeng ZHANG

    Published 2020-01-01
    “…On the basis of researching the timing agreement mechanism and mirror synchronization operation to ob-tain 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 net-work 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 supple-ment 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.…”
