Abstract

The invention discloses a key agreement method, comprising the following steps: when a cloud server receives a random number request sent by a device, it generates a first random number, and returns the first random number to the device; When the cloud server receives the key agreement request message, obtain the device public key and the signature data according to the key agreement request message; decrypt the signature data by using the device public key Obtaining a second random number; when the second random number is consistent with the first random number, the cloud server performs key negotiation with the device. The invention also discloses a cloud server, equipment, a computer-readable storage medium and a key agreement system. The present invention firstly determines the legitimacy of the device when the cloud server and the device perform key negotiation, thereby enhancing the security of the key negotiation process.

Description

technical field [0001] The present invention relates to the technical field of information security, and in particular to a key agreement method, a cloud server, equipment, a computer-readable storage medium, and a key agreement system. Background technique [0002] Smart devices are widely used in daily life. For example, users send instructions to smart devices through terminals to control the smart devices. However, during the key negotiation process between the cloud server and the device, the legitimacy of the device is generally not verified, which has certain risks. [0003] The above content is only used to assist in understanding the technical solution of the present invention, and does not mean that the above content is admitted as prior art. Contents of the invention [0004] The main purpose of the present invention is to provide a key agreement method, cloud server, equipment, computer-readable storage medium and key agreement system, aiming at first determin...
