Internet of things, identity authentication and secret communication method, chip, equipment and medium

Abstract

The invention provides an internet of things, an identity authentication and secret communication method, a security chip, equipment and a medium. The Internet of Things comprises at least one first device and at least one second device, and a security chip is configured in the first device; a white-box cryptographic algorithm is configured in the second equipment; wherein the first equipment performs identity authentication and secret communication with the second equipment through the security chip.

Description

technical field [0001] This application relates to the technical field of communication security, and specifically relates to the Internet of Things, identity authentication and secure communication methods, chips, equipment and media. Background technique [0002] As an extension of the Internet, the Internet of Things is essentially the interconnection of things and things and M2M. It collects information through various sensors distributed in different geographical locations, and integrates the information through the network to achieve centralized management and processing. The open nature of the Internet of Things makes the devices in it vulnerable to attacks. Therefore, in order to realize the "Internet of Everything", secure communication is needed as a technical support, and the prerequisite for realizing secure communication is to ensure the authenticity of the identities of both parties in communication, which requires the use of identity authentication technology ...

AI Technical Summary

Problems solved by technology

[0008] Both the security chip and the white box cipher can be used for M2M identity authentication. The security chip can provide the most secure cryptographic calculation and key storage known, but the cost is relatively high, and it is suitable for devices with high security requirements.
