  • Security verification method and apparatus for attacked smart home Internet of Things system
    Patent number: 11533336
    Abstract: A method and an apparatus for security verification of a smart home IoT system under attack. A finite state machine based on the device description information and IFTTT rules, and a formal specification based on a predefined specification template and input parameters, which uses a model verification tool to perform correctness verification regarding whether the finite state machine satisfies the formal specification, and verifies the output counterexample path by the model verification tool to identify the smart home devices and associated IFTTT rules that cause the system insecure. A state parameter of whether a smart home device is under attack is provided for each smart home device when constructing the finite state machine, and an attack intensity parameter is provided for the system when constructing the formal specification.
