Physical layer encryption method introducing Latin array

Abstract

The invention relates to a physical layer encryption method introducing a Latin array, comprising steps of using a chaotic system and a Latin array to generate a key which is good in performance, using the key to scramble a constellation graph, making distribution of constellation points of various modulation modes on a complex plane toward uniformity, making individual characteristic parameters of various modulation modes toward consistency, achieving a goal of protecting the modulation mode and the modulation information from the physical layer, and fully utilizing the mapped complex plane information to achieve a goal of maximally expanding the key space. The physical layer encryption method introduces an Extract function, fully eliminates the relevance between the chaotic sequences, does not need to generate massive keys on the premise that the key space is guaranteed, greatly reduces the complexity of realizing hardware, performs an NIST random test on a generated key and verifies the unpredictability.

Description

technical field [0001] The invention relates to a physical layer encryption method, in particular to a physical layer encryption method based on Latin matrix and amplitude-to-phase transformation. . Background technique [0002] With the increasing degree of informatization in today's society, traditional business activities, transaction processing, and government services have been increasingly implemented and provided through open computer and communication networks, especially tools based on the World Wide Web. Information security It has become an important guarantee condition for people to survive and develop in the information space. From the perspective of security, the main characteristics of information security include confidentiality, integrity, authentication and non-repudiation. At this stage, ensuring information security based on cryptography is still the main security strategy. But in the communication network, the upper layer encryption mechanism based on...
