The Software-Defined Internet of Things(SD-IoT)achieves effective separation of the network plane and control plane by applying Software-Defined Networking(SDN)technology,thereby significantly enhancing the flexibility and manageability of IoT services.However,its openness also brings additional security challenges.Therefore,it is proposed to integrate Blockchain technology into the SD-IoT architecture,leveraging the decen-tralized and immutable core characteristics of Blockchain to strengthen the security of network control and data ac-cess.Additionally,smart contracts can are used to automatically enforce security policies,and a ciphertext-policy attribute-based encryption scheme can be adopted to ensure the security of data during transmission and storage.
