Problems solved by technology

If there is no encryption during data transmission, it is easy to cause data leakage, and attackers can easily steal data; and the encrypted transmission of data will inevitably occupy system resources. In the case of a certain node computing power, the overall performance of the system will decrease, which may cause network congestion.
At present, the data encryption method generally adopts an asymmetric encryption algorithm that encrypts at the sending end and decrypts at the receiving end. The data transmission method used in the Internet of Things environment still has the disadvantages of easy cracking, low security, and large amount of calculation.

[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., which is not limited in the present invention. The flow chart is as follows figure 1 shown, including the following steps:

[0046] Step 101: The sender receives the 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. Further, 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; or it can be retrieved from the sender's own database after establishing a connection with the receiver. The present invention does not make any limitation on...

[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., which is not limited in the present invention. The flow chart 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 transmitting end.

[0068] Specifically, the receiver is connected to the network link and can receive data sent by different senders. The original data sent by the sender is received by the receiver after passing through the sender's gateway and a relay device such as a device cloud, an operation cloud, and / or a remote server. In the process of data transmission, digital signature and encryption are set on the original data by using the sender gateway on the data transmission link and the identifier of each relay de...

[0077] like 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 the following:

[0078] a receiving module 301, for receiving original data;

[0079] A setting module 302 is used to digitally sign and encrypt the original data according to the gateway identifier and the identifier of the relay device;

[0080] The sending module 303 is configured to send the digitally signed and encrypted original data to the receiving end; wherein the gateway identifier is the gateway identifier of the system gateway or the gateway identifier of the receiving end gateway.

[0081] Further, the setting module 302 may include: a first sending unit, a parsing unit and an encryption unit, the details are as follows:

[0082] a first sending unit, configured to digitally sign and encrypt the original data according to the gateway identifier, and send the original data ca...

Abstract

The present invention relates to a data transmission method in an internet of things. Data is transmitted between terminals in an internet of things environment; a transmit end sends original data to network data transmission devices; the network data transmission devices sequentially add a digital signature to each piece of data; and the final network data transmission device verifies all digital signatures of the received data, determines that the data is from the transmit end through a set path, and then sends the original data to a receive end. The present invention further provides a data transmission system in the internet of things and a data transmission apparatus in the internet of things. The data is singed when passing each hardware device in transmission, a later receiving device can verify the signature, so that multiple nodes on one communication chain are managed safely and effectively, the whole communication chain is ensured to communicate safely, and a non-credit person is prevented from intruding and controlling the device.

Description

technical field [0001] The invention belongs to the field of data transmission, and in particular relates to a data transmission method, system and device in the Internet of Things. Background technique [0002] The Internet of Things (Internet of Things) is an information carrier based on the Internet and traditional telecommunication networks. It uses technologies such as RFID, wireless data communication, and appropriate information security mechanisms to provide safe, controllable and even personalized real-time online monitoring and positioning. Management and service functions such as traceability, alarm linkage, dispatch command, plan management, remote control, security prevention, remote maintenance, decision support, etc., enable all common physical objects that can be independently addressed to achieve interconnection and interoperability. The integration of "management, control, and operation" of "high efficiency, energy saving, safety, and environmental protecti...
