Problems solved by technology
However, most existing symmetric key generation schemes based on physical mechanisms are not suitable for IoT security application scenarios in a broader sense.
First, the symmetric key generation rate of existing schemes is not high
The theoretical data transmission rate of 5G can reach the order of Gbps, and the existing physical mechanism-based symmetric key generation rate is lower than this order of magnitude.
Another example is that sound waves attenuate quickly, and there are distance requirements for security solutions based on sound wave characteristics.

Embodiment Construction
[0036] The concrete realization process of the present invention is as follows:
[0037] 1. Network model and attack model
[0038] 1.1 Network Model
[0039] In the system implemented by the present invention, at least two devices are included. For the convenience of description, the two devices are called Alice and Bob respectively, and are the sender and receiver of the data transmission, respectively. Both Alice and Bob are ordinary IoT devices. Alice is responsible for collecting data, and compressing and encrypting the data. The present invention refers to compression and encryption operations collectively as encoding operations. Alice sends the encoded result to Bob through the public communication channel. The present invention does not involve communication details such as modulation and demodulation. After Bob decodes the received data, he obtains the final result. The decoding operation mainly involves decompression and decryption. Real-life IoT devices are ...

Data transmission efficiency and data privacy are important research topics for IoT data transmission. The present invention proposes a safe and efficient data transmission encoding and decoding method based on superlattice and compressed sensing technology to solve the two objectives of data transmission efficiency and privacy protection of the Internet of Things. The present invention constructs a lightweight data encoding and decoding method that simultaneously supports compression and encryption by combining the superlattice symmetric key and compressed sensing technology, so as to ensure the efficiency and privacy of data transmission. This method can also be extended to other network application scenarios outside the Internet of Things.
Description
technical field [0001] The invention relates to the field of the Internet of Things, and relates to a coding and decoding method for safe and efficient data transmission of the Internet of Things. Background technique [0002] The arrival of the 5G era will accelerate the large-scale application of the Internet of Things. The Internet of Things is the application field with the greatest growth potential in the 5G era. 3GPP, a world-renowned telecommunications standard-setting organization, has defined three major 5G application scenarios. There are two major application scenarios for IoT-related application fields, they are mMTC (massive MachineType of Communication) for large-scale machine type communication and uRLLC (Ultra-reliable and Low) for scenarios such as Internet of Vehicles Latency Communications, high reliability and low latency communications). The arrival of the 5G era will accelerate the development of IoT-related industries such as industrial Internet, sm...
