An Encryption Algorithm for Long-Distance Data Transmission in the Internet of Things Based on Channel Nonlinear Transformation

Communication and information transmission can be seen everywhere in people's lives, and its safety is extremely important. In order to further improve the security of data transmission in communication, in addition to adopting traditional source encryption codes, it is also very necessary to increase channel encryption measures. This thesis focuses on channel encryption, introduces and analyzes the encryption algorithm for long-distance data transmission in the Internet of Things based on channel nonlinear transformation. At the same time, in order to verify the feasibility, reliability and confidentiality of the above-mentioned channel encryption method, a verification communication system was designed.
