Embodiment Construction

[0090] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0091] The invention provides a key negotiation method. The invention realizes that the equipped network equipment automatically searches for the undistributed network equipment, and after verifying that the undistributed network equipment is legal, it encrypts the distribution network information and sends it to the undistributed network equipment, realizing the undistributed network equipment. Network devices automatically connect to the network, thereby improving the communication security of home devices.

[0092] like figure 1 as shown, figure 1 It is a schematic diagram of the hardware operating environment of the terminal involved in the solution of the embodiment of the present invention.

[0093] The terminal in this embodiment of the present invention may be a smart device, such as an air conditioner, an a...

Abstract

The invention discloses a key agreement method, which comprises the following steps: when a distributed network device discovers an undistributed network device, a first random number is generated, and the first random number is sent to the undistributed network device; at that time of receiving the key negotiation request message, the distribute network equipment obtains the public key of the undistributed network equipment and the cipher text data according to the key negotiation request message; the ciphertext data is decrypted through the public key of the undistributed network device to obtain a second random number; when the second random number coincides with the first random number, the allocated network device performs key agreement with the unallocated network device. The invention also discloses a device, a computer-readable storage medium and a key agreement system. The invention realizes the automatic connection of the unallocated network equipment to the network, therebyimproving the communication safety of the household equipment.

Description

technical field [0001] The present invention relates to the technical field of information security, and in particular to a key agreement method, a network-distributed device, an undistributed network device, a computer-readable storage medium, and a key agreement system. Background technique [0002] With the continuous development of information technology, smart devices are widely used in life. When a new device is configured to the network, generally the configured network device directly broadcasts the key, and sends the network configuration information to the new device, so that the new device can join the network. However, the already configured network equipment generally does not verify the validity of the new equipment, 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] T...
