Problems solved by technology

[0004] However, once the attacker intercepts and deciphers the encrypted data and the parameters of the data, the meaning of the corresponding data can be clarified according to the parameters of the data, and then the data can be tampered with, so the security of the data cannot be guaranteed.

Embodiment Construction

[0044] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0045] An embodiment of the present invention provides a data processing method, such as figure 1 As shown, the method includes:

[0046] Step 101, the server receives encrypted data information from the IoT device.

[0047] Among them, the encrypted data information is generated by the IoT device using a preset algorithm and using the first key to encrypt the target data and parameter information. The first key is the IoT device using a preset algorithm and using the length of the target data and the first key Two keys are generated, ...

Abstract

The embodiment of the present invention discloses a data processing method and device, including: the server receives encrypted data information from an Internet of Things device; uses a preset algorithm and uses its own pre-stored first key to decrypt the encrypted data information to obtain target data and parameter information; using a preset algorithm, and using the length of the target data and the first key to obtain a second key; and obtaining the corresponding relationship between the target data and the associated parameters according to the second key and parameter information. It can be seen from the technical solution provided by the embodiment of the present invention that the server can obtain the information of the parameters of the data from the second key only by using the preset algorithm determined in advance with the terminal, and then clarify the corresponding meaning of the data, thus preventing the attacker from knowing The meaning of the data is tampered with to ensure the security of the data.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of the Internet of Things, and in particular, to a data processing method and device. Background technique [0002] Narrow Band Internet of Things (NB-IoT) is a new low power wide area network (Low Power Wide Area Network, LPWAN) technology for narrowband cellular communication, which is widely used in the low-rate business market. However, as the security of the network environment becomes worse and worse, NB-IoT technology is also facing security threats such as data tampering. Therefore, how to ensure the security of device data has become an urgent problem to be solved in the practical application of NB-IoT technology. [0003] In related technologies, when an NB-IoT device sends data to a server, it encrypts the data together with the parameters to which the data belongs, and then sends the encrypted data and the parameters to which the data belongs to the server. [0004] Howeve...
