[0045] The inventor provides a data transmission method in the Internet of Things, which is used to improve the security of data transmission, wherein the execution subject can be a mobile phone, a smart watch, a computer, etc. The present invention does not make any limitation on this, and the specific details of the method The schematic diagram of the process is as follows figure 1 shown, including the following steps:
[0046] Step 101, the sending end receives original data.
[0047] Specifically, when the sender receives the original data, the sender can correspond to multiple receivers at the same time; it can also be that the sender is ready to send data to the receiver when it receives the transmission signal from the receiver. Furthermore, the sender can receive the original data from a third-party device, where the third-party device can be a pre-established trusted terminal or server; it can also be retrieved from the sender's own database after establishing a conn...

[0066] The inventor provides a data transmission method in the Internet of Things, which is used to improve the security of data transmission, wherein the execution subject can be a mobile phone, a smart watch, a computer, etc. The present invention does not make any limitation on this, and the specific details of the method The schematic diagram of the process is as follows figure 2 shown, including the following steps:
[0067] Step 201, the receiving end receives the original data with digital signature and encryption sent by the sending end.
[0068] Specifically, the receiving end is connected to a network link and can receive data sent by different sending ends. The original data sent by the sending end is received by the receiving end after passing through the sending end gateway and relay devices such as device cloud, operation cloud and / or remote server. In the process of data transmission, the original data is digitally signed and encrypted using the identificatio...

[0077] Such as image 3 As shown, a data transmission system in the Internet of Things includes a receiving module 301, a setting module 302, and a sending module 303; specifically, it includes as follows:
[0078] A receiving module 301, configured to receive raw data;
[0079] A setting module 302, configured to digitally sign and encrypt the original data according to the gateway ID and the relay device ID;
[0080] The sending module 303 is configured to send the digitally signed and encrypted original data to the receiving end; wherein, the gateway identification is the gateway identification of the system gateway or the gateway identification of the receiving end gateway.
[0081] Further, the setting module 302 may include: a first sending unit, an analyzing unit and an encrypting unit, specifically as follows:
[0082] The first sending unit is configured to digitally sign and encrypt the original data according to the gateway identifier, and send the original data c...
