Cloud security authentication method and authentication device

Abstract

The invention provides a cloud security authentication method, comprising a cloud authentication step that an authentication device carries out signature through utilization of a device private key stored in the authentication device, thereby obtaining a device authentication data packet, the authentication device sends the device authentication data packet to the cloud, and a cloud receives the device authentication data packet and then carries out signature authentication on the device authentication data packet through utilization of a device public key stored in the cloud; and an authentication device authentication step that a cloud device carries out signature through unitization of a cloud private key stored in the cloud, thereby obtaining a cloud authentication data packet, the cloud sends the cloud authentication data packet to the authentication device, and the authentication device receives the cloud authentication data packet and then carries out signature authentication through utilization of a cloud public key stored in the authentication device. The invention also relates to the cloud security authentication device. According to the method and the device, the deviceauthentication security is improved, moreover, the authentication cost is low, and the hardware cost does not need to be increased.

Description

technical field [0001] The invention relates to a security authentication method, in particular to a cloud security authentication method. Background technique [0002] Today, smart devices such as smart TVs in meeting rooms, smart heating and air conditioning systems, internet-connected lights, manufacturing processes controlled by smart devices, smart watches and fitness equipment can be said to be almost everywhere. And these are just a very small part of the current enterprise Internet of Things (IoT). On a larger scale, almost any physical object can be intelligently connected to the network. [0003] With the development of the Internet of Things and Industry 4.0, security issues have become a key factor hindering the promotion of industry applications. How to solve the security risks brought by the massive Internet of Things devices connected to the Internet, security companies have also proposed various targeted solutions. , To a certain extent, it solves the secur...

AI Technical Summary

Problems solved by technology

At present, before the networked communication between smart devices and cloud servers, there is generally no two-party authentication process between devices and cloud networks, which poses security risks.
