Key exchange method and device

Abstract

The embodiment of the invention provides a key exchange method and device applied to an articulated naturality web client, and the articulated naturality web client is in communication connection withan articulated naturality web streaming media server through an articulated naturality web core server; the method comprises the steps of enabling the articulated naturality web client to send a connection establishment request to the articulated naturality web streaming media server, wherein the connection establishment request comprises a first public number; receiving a request response message returned by the articulated naturality web streaming media server for the connection establishment request, wherein the request response message comprises a second public number; generating a firstsecret key according to the second public number; and encrypting to-be-transmitted articulated naturality web protocol data by adopting the first key to obtain encrypted data, and sending the encrypted data to the articulated naturality web streaming media server, thereby realizing secure exchange of the key in an articulated naturality web environment, encrypting the data by utilizing the key, improving the security during articulated naturality web protocol data transmission, and effectively preventing data leakage.

Description

technical field [0001] The invention relates to the technical field of Internet of Things, in particular to a key exchange method and device. Background technique [0002] With the development of science and technology, Internet of Vision technology has been more and more widely used, such as high-definition video conferencing, video surveillance, TV mail, personalized recording, etc. Internet of Vision technology has brought great convenience to life, entertainment and office. [0003] In the Internet of Vision, the Internet of Vision terminals transmit data in plain text, that is, use unencrypted data to transmit among each Internet of Vision terminals, although the communicating Internet of Vision terminals can negotiate the key used when encrypting data and decrypting data, Encrypt the unencrypted data to improve data security, however, when the key is exchanged, there will be a risk of the key being leaked during transmission, and the security is low. Contents of the ...
