Channel Coding Information Hiding Technology Based on Spacecraft Application

摘要

Nowadays, information resources have become the most important part of resources in the Internet era, and the problems of information security have become the research hotspot. Channel coding information hiding technology is a new type of information hiding technology, which has been widely studied in the field of communication, but there is little research on the application of spacecraft. Based on this, this paper studies a channel coding information hiding technology based on spacecraft application. In the research, this paper mainly uses the good randomness and security performance of chaotic sequences, applies them to the random coding of encrypted information, and realizes the hiding of encrypted information. In the simulation analysis, it can be found that the channel coding information hiding technology proposed in this paper has good encryption performance, and when the channel bit error rate is set to 5 × 10~(-3), the recovered information error rate is 0, and the encrypted information can be recovered without error.
