Embodiment 1

[0078] An Internet of Things device for avoiding data tampering, characterized in that said Internet of Things device includes:

[0079] The data collection module S is used to obtain environmental detection data;

[0080] The data processing module P is used to perform certain calculation processing on the data;

[0081] The data storage module D is used to store key parameters of the device;

[0082] The communication module N is used to connect to the remote data platform, send data to the data management center, or receive relevant instructions;

[0083] The working process of the described IoT device is as follows:

[0084] (1) The information collection module S transmits the environmental detection data data to the data processing module P;

[0085] (2) The data processing module P reads the device's identity ID, encryption key ck and integrity protection key ik from the data storage module D;

[0086] (3) The data processing module P reads the system clock data T, ...

Embodiment 2

[0088] The present invention also provides an Internet of Things data security transmission system that avoids data tampering, including an Internet of Things device E, and a data management center M, and the Internet of Things device E sends data to the data management center M, so The above-mentioned data management center M carries out corresponding processing, and its processing process comprises the following steps:

[0089] 1) The IoT device E uses the encryption algorithm Enc and the encryption key ck to calculate c=Enc ck (data), using the MAC algorithm and the data integrity protection key ik to calculate the data integrity protection label t=MAC(ik, ID, T, data);

[0090] 2) The IoT device E sends data (ID, T, c, t) to the data management center M;

[0091] 3) After the data management center M receives the data (ID, T, c, t) in step 2), it searches for the key ck according to the ID, and decrypts c using the key ck and the decryption algorithm corresponding to Enc ...

Embodiment 3

[0115] The present invention provides a method for secure transmission of IoT data that avoids data tampering. The method for secure transmission of IoT data is to add a data header h to the data sent by the IoT device E to the data management center M ; The data management center M performs the following steps after receiving the data sent by the data management center M:

[0116] 1) Determine how to operate according to the data header h: if the value of h indicates that the data has not been encrypted, then use the original system method for processing; if the value of h indicates that the data has been encrypted, then according to the value of h Judging the encryption result of which data the ciphertext c is;

[0117] 2) According to the value of h, execute the entire operation process of step 3) in the data transmission and processing steps between the IoT device E and the data management center M.

[0118] Wherein, when calculating the data integrity protection label t,...

Abstract

The invention relates to the technical field of electronic products, in particular to Internet of Things equipment capable of avoiding data tampering and a data secure transmission method and system. Comprising a data acquisition module S, a data processing module P, a data storage module D and a communication module N, a data encryption key ck shared with a data center and a data integrity protection key ik shared with an industry competent department are written into the Internet of Things equipment, the Internet of Things equipment encrypts transmitted data, then performs integrity protection, and transmits a processing result to a data processing center, so that the data integrity protection is realized. And the competent department performs integrity verification on the called detection data, if the verification is passed, the detection data is indeed the original data from the Internet of Things equipment, otherwise, the data is wrong, including the possibility that the detection data is tampered by the data processing platform.

Description

technical field [0001] The invention relates to the technical field of electronic products, in particular to an Internet of Things device, a data secure transmission method and a system for avoiding data tampering. Background technique [0002] The Internet of Things is the integration of a variety of cutting-edge information technologies, which have been widely used in many industries. The basic architecture of the Internet of Things includes a perception layer, a transmission layer, and a processing application layer, so one application of the Internet of Things system is environmental monitoring, including air temperature and humidity monitoring, water quality monitoring, water level water flow rate monitoring, water pollution monitoring, special harmful substances ( gas or liquid) concentration monitoring, etc. These monitoring are done through special sensors, and then transmitted to the data management center of the industry or enterprise for processing. When a large...
