Intelligent equipment network communication security implementation method based on Internet of Things

Abstract

The invention discloses an intelligent device network communication security implementation method based on the Internet of Things. The method comprises steps that an intelligent device initiates an authentication request; the intelligent device encrypts the service data packet and sends the encrypted service data packet to a server; the server verifies legality of the intelligent equipment; the server encrypts the service data packet and sends the encrypted service data packet to the intelligent device; the intelligent equipment verifies legality of the server; wherein the service data packetcomprises an encryption area and a verification area, all data in the encryption area is encrypted and comprises service data, a unique serial number of equipment and signature data, and a signaturevalue of a requester or a responder is stored in the verification area and is used for identity verification and data tampering check. According to the method, encryption and decryption keys and the identity authentication information of each communication change randomly, so repeated data attacks can be effectively resisted; secret key management is carried out by adopting a secret key group anda secret key index, and two communication parties do not carry out secret key related information interaction all the time, so security of a secret key is ensured.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for implementing network communication security of smart devices based on the Internet of Things. Background technique [0002] With the continuous development of the Internet of Things technology, the number of Internet of Things smart devices (hereinafter referred to as smart devices) is increasing exponentially, and the network communication methods are changed from the original Wi-Fi, GSM (Global System for Mobile Communications, Global System for Mobile Communications), LTE (Long Term Evolution, long-term evolution technology) has developed to the current NB-IoT (Narrow Band Internet of Things, narrowband Internet of Things). At present, most smart devices do not have any security measures for network communication due to the consideration of development costs and operation and maintenance costs, and only a small number of devices have adopted certain ...
