Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some parts related to the present invention are shown in the drawings but not all structures.

[0029] Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe various operations (or steps) as sequential processing, many of the operations may be performed in parallel, concurrently, or simultaneously. In addition, the order of operations can be rearranged. The process may be terminated when its operations are complete, but may also have additional steps not inclu...

Abstract

The embodiment of the invention discloses a video interaction method and device, electronic equipment and a storage medium. The method comprises the following steps: determining a current excitation value required for video interaction between management equipment and target node equipment; encrypting and decrypting target video data interacted between the management device and a target node device according to the current excitation value. A node device can generate a unique feedback value under the excitation effect of an excitation value, and node devices with different physical characteristics generate different feedback values under the effect of the same excitation value, wherein the feedback value is used for encrypting and decrypting video data interacted between devices. By adopting the scheme of the invention, the negotiation of the video secret key can be realized under the condition that the management equipment and the Internet of Things node or the client node do not need to interact the secret key required by encryption and decryption, and the security of the video data and the encryption and decryption secret key is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of video processing, and in particular, to a video interaction method, device, electronic equipment, and storage medium. Background technique [0002] In the Internet of Things system, the data interaction between each node and the management server requires passwords, especially the transmission of video data, which requires the use of symmetric keys to encrypt and interact with video data. [0003] At present, in order to ensure that the symmetric key is not intercepted, it is usually encrypted and protected by the asymmetric key of PKI; that is, the management server uses the public key of each node to encrypt the symmetric key, and each node uses the private key to decrypt Get the symmetric key in it. However, the PKI system is relatively expensive and requires a third party to be reliably implemented, and the security of each node's private key is low, which easily leads to securi...
