The rapid development of the Internet of Things (IoT) has made impressive achievements, raising a heated discussion about IoT big data, in which data security and privacy issues are key concerns. Due to the ubiquity of IoT, IoT big data has not only brought convenience to people's daily lives, but also increased the potential attack surfaces for cybercriminals. At the same time, considering the characteristics of resource constraints and heterogeneity, with traditional network security solutions it can be difficult to achieve ideal results in the IoT environment, which further exacerbates the challenges faced by IoT big data security. In this case, the advantages introduced by software defined networking (SDN) have the potential to meet the challenges of IoT security risks. To this aim, we propose an ID-based SDN secure network architecture called IBSDN. Different from the traditional SDN solution, IBSDN is committed to providing IoT with endogenous trusted services on the network side by embedding unforgeable terminal identities in the data stream. This network-level trusted service can prevent IoT terminals from consuming restricted resources for the sake of security, providing greater scalability and manageability for network security monitoring.
