A communication connection method, system, Internet of Things device system, and storage medium

Abstract

The present application discloses a communication connection method, system and storage medium, which are applied to an Internet of Things device system. The Internet of Things device system includes an authentication server, a network service management platform, and a sensor node. The method includes: initializing the authentication server and Public key parameters, so that each node generates its own public key and private key according to the key parameters; the private key is updated according to the current time; when the sensor node requests to join, it receives the inspection application group through the network service management platform; The verification application group is decrypted by the private key at the current time, and the identity information of the network service management platform and the sensor node is verified according to the decryption result; the verification result is sent to the network service management platform and the sensor node, so that the network Any one of the service management platform and the sensor node establishes a communication connection after determining the security of the identity information of the other party, which enhances the security of communication between devices in the IoT device system.

Description

technical field [0001] The present application relates to the technical field of communication, and more specifically, to a communication connection method, system and device, and a computer-readable storage medium. Background technique [0002] At present, IoT devices have been widely used in military and national defense, environmental monitoring, medical health, industry and data monitoring in high-risk areas. Its application value and scientific research value have been highly concerned by countries all over the world. Since the architecture of IoT devices is open, some of its own characteristics determine that the security of the network is poor, and criminals can easily eavesdrop, intercept and forge the transmitted information, so security has become an urgent problem for IoT devices. one of the key issues. [0003] The identification and verification method in the prior art includes the following steps: 1) the second certification system sends message 1 to the firs...

Problems solved by technology

In this case, the communication data will be eavesdropped by the attacker during the transmission process. Once the eavesdropper obtains the digital certificate directly encrypted by each unit, the system information will be completely controlled by the attacker.
