Communication connection method and system, Internet of Things (IoT) equipment system and storage medium

Abstract

The invention discloses a communication connection method, a communication connection system and a storage medium, applied to an Internet of Things (IoT) equipment system. The IoT equipment system comprises an authentication server, a network service management platform and a sensor node. The method comprises the steps as follows: the authentication server initializes and opens a key parameter, sothat each node generates a public key and a private key according to the key parameter; the private key updates according to current time; when a sensor node request is added, an verification application sub-group is received via the network service management platform; the verification application sub-group is subjected to a decryption operation according to the private key at the current time,and identity information of the network service management platform and the sensor node are verified according to a decryption result; a verification result is sent to the network service management platform and the sensor node, so that any one of the network service management platform and the sensor node builds a communication connection after judging that the identity information of the other party is safe. The security of communication between the equipment in the IoT equipment system is enhanced.

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...

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.
