Abstract: The rapid development of network communication puts forward higher requirements for the security of communication, and chaotic encryption technology is a mature and effective method in the field of security and secrecy. In this study, the application of chaotic encryption technology in network communication security and confidentiality was studied. Firstly, the chaotic encryption technology was briefly introduced. Then a network communication system based on chaotic encryption technology was established, and the specific establishment process was analyzed. Finally, National Institute of Standards and Technology (NIST) randomness test, secret key sensitivity test and confidentiality analysis based on information throughput were carried out to analyze the security and confidentiality of the system. The results showed that the system passed NIST randomness test, effectively defended the external attacks, and kept a favourable stability of confidentiality under different throughput. The experimental results proves the good security of chaotic encryption algorithm in the field of network communication and provides some bases for its specific application.
