Abstract

The invention provides an IoT (Internet of Things) equipment authentication and key agreement method and device. According to a technical scheme, an IoT control center generates an authentication code for the IoT equipment and sends the code to the IoT equipment, generates key information of the IoT equipment, utilizes the authentication code for encrypting the key information and thus obtains the cryptograph and calculates the verification information, and sends the cryptograph and the verification information to the IoT equipment. The IoT equipment utilizes the authentication code information cryptograph for decryption and obtains the key information, and implements IoT equipment authentication according to the verification information. The method and device can be used for realizing IoT communication security.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for authentication and key agreement of an Internet of Things device. Background technique [0002] The Internet of Things (IOT) is an information carrier based on the Internet, traditional telecommunication networks, etc., which enables all ordinary physical objects that can be independently addressed to realize interconnection and intercommunication. In the Internet of Things, everyone can use electronic tags to connect real objects to the Internet, and their specific locations can be found on the Internet of Things. Through the Internet of Things, the central computer can be used to centrally manage and control machines, equipment, and personnel, and can also remotely control home equipment and cars, search for locations, and prevent items from being stolen. [0003] The development of the Internet of Things has pushed the world into the era...
