Internet of Things terminal security authentication method based on security chip

Abstract

The invention discloses an Internet of Things terminal security authentication method based on a security chip. Whole-process safety guarantee of three stages of registration service interaction, authentication service interaction and data service interaction between the Internet of Things terminal and the cloud server is completed. Security authentication is carried out in a mode of combining hardware authentication such as product digital signature authentication and software authentication such as security chip temporary terminal digital signature authentication, and the relatively strong defense capability can be provided for both hardware attacks and software attacks. Besides, all operations related to encryption and decryption are carried out by the cloud and the two ends of the security chip, the communication terminal is transparent, only data acquisition, processing and forwarding are carried out by the communication terminal, and security calculation is not carried out, so that separation of security logic and service logic is realized, the coupling degree of the whole system is reduced, and a higher security level is achieved.

Description

technical field [0001] The present application relates to the field of the Internet of Things, in particular to a method for security authentication of an Internet of Things terminal based on a security chip. Background technique [0002] In recent years, with the continuous development of IoT technology and the increasing number of IoT devices, the vulnerabilities of IoT devices have also been gradually exposed. Whether it is botnets, worms, DDoS attacks, or replay attacks, they are all at a faster rate. IoT devices are threatened in more subtle and complex ways. [0003] From small smart bracelets, smart watches, to web cameras, to smart door locks, while IoT technology brings convenience to our work and life, it also introduces various risks. Compared with the PC Internet and mobile Internet, due to the wide variety of devices, the huge number, and the complex and concealed attack methods, the security problems in the Internet of Things era have become more serious. If t...
