A Secure IoT Transmission Scheme Based on Edge Computing
Bingheng Qi · 2021
IoT security is one of the most important challenges for the development of IoT. A large number of resource-constrained nodes in IoT have insufficient storage space, limited computing power, unstable communication links, and cannot adopt internet standard security protocols to guarantee the end-to-end security of communication, which becomes the weakness of IoT. Combining the characteristics and development trend of IoT, this paper proposes an edge computing based IoT security architecture and proposes a novel security transmission scheme. In this scheme, an end-to-end security approach based on proxy datagram transport layer security is adopted. Analysis and experiments show that the scheme can enable resource-constrained devices in the IoT to communicate securely end-to-end using internet-standard security protocols, and has good scale, scalability, and practical feasibility.
