背景技术Background technique
保密通信是研究通信中信息保密技术的科学，能信学科的分支，其具体是指采取了保密措施的通信，除采用暗号、隐语、密码等保密措施外，现代保密通信主要采用信道保密和信息保密，信道保密是采用使窃密者不易截收到信息的通信信道，如采用专用的线路、瞬间通信和无线电扩频通信等，信息保密是对传输的信息用约定的代码密码等方法加以隐蔽再传送出去，随着电子技术的发展，已采用保密机进行保密，其特点是对传输的信息在发送端进行变换加密处理，接收端按相反过程还原信息，使窃密者即使收到信号，也不明信号所代表的内容，数据通信的迅速发展带来了数据失密问题，信息被非法截取和数据库资料被窃的事例经常发生，在日常生活中信用卡密码被盗是常见的例子。数据失密会造成严重后果，所以数据保密成为十分重要的问题；因此，发明出一种基于分数阶傅里叶变换阶次复用的保密通信方法变得尤为重要。Secure communications is the science that studies information security technology in communications, a branch of the science of trust. It specifically refers to communications that adopt security measures. In addition to using secret codes, lingoes, passwords and other security measures, modern secure communications mainly use channel confidentiality and information security. Confidentiality, channel confidentiality is the use of communication channels that make it difficult for eavesdroppers to intercept information, such as the use of dedicated lines, instantaneous communication and radio spread spectrum communication, etc. Information confidentiality is the use of agreed codes and passwords to conceal the transmitted information. With the development of electronic technology, secret machines have been used for confidentiality. Its characteristic is that the transmitted information is transformed and encrypted at the sending end, and the receiving end restores the information according to the reverse process, so that even if the eavesdropper receives the signal, he will not know it. The content represented by the signal, the rapid development of data communication has brought about the problem of data confidentiality. Instances of illegal interception of information and theft of database data often occur. Stolen credit card passwords are common examples in daily life. Data confidentiality will cause serious consequences, so data confidentiality has become a very important issue; therefore, it is particularly important to invent a secure communication method based on fractional Fourier transform order multiplexing.
