Abstract

The invention discloses a data communication method and device. The method comprises the following steps: when transmitting end equipment performs data communication with receiving end equipment, acquiring an equipment identification code, accumulated running duration and current communication times with the receiving end equipment of the receiving end equipment, and generating a first dynamic keyin real time according to the equipment identification code, the accumulated running duration and the current communication times; encrypting the communication data to be sent according to the firstdynamic key by a sending end device to obtain encrypted data; and sending the encrypted data to receiving end equipment by a sending end equipment, wherein the receiving end equipment is used for generating a second dynamic key after receiving the encrypted data and decrypting the encrypted data by adopting the second dynamic key to obtain communication data, and the second dynamic key is the sameas the first dynamic key. The technical problem that in the prior art, in the communication process between the intelligent device and the server, the data security is low is solved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular, to a data communication method and device. Background technique [0002] In the process of communication between the smart device and the server, if the data is not encrypted during the communication process, the control device will be forged and the private information of the device will be stolen; the communication process using a fixed key for data encryption in the prior art In the process of using third-party certificates for data encryption in the existing technology, not only does it require a certain amount of money, but it is also affected by the network of the third-party organization, and the third-party certificate organization will be forged by a forged middleman. Therefore, there is a technical problem of low data security in the communication process between the smart device and the server in the prior art. [0003] For the above problems, no effective...
