Abstract

The invention discloses a data transmission method, a cloud server, a receiving end and a sending end. The method comprises the steps: acquiring a first request, sent by a receiving end, of data transmission, wherein the first request comprises a service request, a second encryption code of the receiving end and a first encryption code of a sending end, the first encryption code comprises first identity information and first secret key information, and the second encryption code comprises second identity information and second secret key information; according to the first identity information and the second identity information, determining whether the receiving end and the sending end have a binding relationship; under the condition that the receiving end and the sending end have the binding relationship, sending a second request to the sending end, wherein the second request comprises the service request and the first encryption code, and the second request is used for the sending end to encrypt the transmitted service data through a key corresponding to the first key information of the second request. According to the invention, the technical problem of poor data transmission security caused by easy interception of a data transmission method in the prior art is solved.

Description

technical field

[0001] The present invention relates to the field of data transmission, in particular to a data transmission method, a cloud server, a receiving end and a sending end. Background technique

[0002] There are some schemes for encrypted transmission of data in the prior art. Most of these schemes use a specific encryption algorithm to encrypt the data, and then transmit the encrypted data and key to the receiving end; and for the receiving end, Then the data can be decrypted according to the received key. However, this method cannot completely guarantee data security, because the data transmitted on the network is very easy to be illegally intercepted, and at the same time, the key is also intercepted, so that after others illegally obtain the transmitted data, they can also carry out the obtained data. Decrypt to obtain confidential data.

[0003] For the above problems, no effective solution has been proposed yet. Contents of the invention
