Secure and efficient data transmission method based on superlattice and compressed sensing

Abstract

Data transmission efficiency and data privacy are important research subjects of Internet of Things data transmission. The invention provides a secure and efficient data transmission encoding and decoding method based on superlattice and compressed sensing technologies, so as to solve two major goals of Internet of Things data transmission efficiency and privacy protection. According to the method, the superlattice symmetric key and the compressed sensing technology are combined to construct a lightweight data encoding and decoding method which supports compression and encryption at the same time, so as to ensure the efficiency and privacy of data transmission. The method can also be popularized to other network application scenes except the Internet of Things.

Description

technical field [0001] The invention relates to the field of the Internet of Things, and relates to encoding and decoding methods for safe and efficient data transmission of the Internet of Things. Background technique [0002] The advent 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. Among them, there are two major application scenarios for IoT-related application fields. They are mMTC (massive Machine Type of Communication, large-scale machine type communication) for large-scale machine type communication and uRLLC (Ultra-reliable and Low Latency Communications, high reliability and low latency communication). The advent of the 5G era will accelerate the development of IoT-related industries such as industrial Inter...

AI Technical Summary

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.
