Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a security authentication communication system, method and Internet of Things device in a fog computing environment. Background technique [0002] At present, in order to realize various IoT applications, more and more IoT devices are connected to the Internet. The vast amounts of data generated by these devices need to be analyzed and processed. It is obviously not advisable to transmit all data directly to the cloud for centralized processing. This is due to the physical distance between the cloud and the IoT devices, and the large amount of data is transmitted remotely. This can cause severe network delays, thereby affecting the quality of service of IoT applications. . To solve this problem, fog computing came into being. Fog computing extends the capabilities of cloud computing to the edge of the network, providing computing, storage and network services...

AI Technical Summary

Problems solved by technology

[0003] From the perspective of effectiveness and security, the current technology mainly has the following problems: (1) some schemes use cloud servers to achieve secure communication between fog nodes and IoT devices, which obviously increases the authentication delay; (2) Most security schemes cannot guarantee authentication security when the fog node is destroyed; (3) When an IoT device is registered in a fog node, the fog node moves out of the fog area, and the IoT device cannot communicate with other nodes in the fog area. authentication, which causes the IoT device to have to re-register

(4) Most secure authentication communication schemes are not lightweight and not suitable for resource-constrained IoT device implementations

[0004] Through the above analysis, the existing problems and defects of the existing technology are: the existing communication system or communication method, the authentication delay is high, the authentication security cannot be guaranteed, the authentication communication scheme is not lightweight, and is not suitable for resource-constrained IoT devices implementation; and IoT devices need to re-register after the registration node moves out of the fog zone

[0005] The difficulty of solving the above problems and defects is: Since some fog nodes and IoT devices are installed in public areas, they are easy to be faked and attacked. When one of them is attacked or faked, the communication should also be safe
