A method is presented for one-to-many information encryption transmission by using temporal ghost imaging and code division multiple access. In the encryption transmission process, code division multiple access technologies combine multiple information sources, and the chip sequence corresponding to each set of information is used as the first key. The transmission end loads the transmission information onto a series of temporal random patterns of temporal ghost imaging and transmits it to the receivers. A series of temporal random patterns is the second key. During the decryption, each receiver can get the same encrypted information and use the second key to obtain the transmitted information. Finally, each receiver uses the unique chip sequence to get corresponding information. This encryption transmission method realizes one-to-many information encryption transmission at the same time over the same channel. Double encryption ensures the security of information. Simulation and experiment results verify the effectiveness and security of the method. The method has strong antinoise ability and can effectively resist various attack modes. At the same time, this method solves the problem that the use of code division multiple access enlarges the signal bandwidth, and ensures that no cross talk occurs between various sources of information.

基于时间重影和码分多址的一对多光信息加密传输方法

提出了一种利用时间重影成像和码分多址进行一对多信息加密传输的方法。在加密传输过程中，码分多址技术结合了多个信息源，以每组信息对应的码片序列作为第一密钥。传输端将传输信息加载到时间重影成像的一系列时间随机模式上，并传输到接收端。一系列时间随机模式是第二个关键。在解密过程中，每个接收者都可以获得相同的加密信息，并使用第二个密钥来获取传输的信息。最后，每个接收器使用唯一的码片序列来获取相应的信息。这种加密传输方式实现了在同一信道上同时进行一对多的信息加密传输。双重加密确保信息安全。仿真和实验结果验证了该方法的有效性和安全性。该方法抗噪能力强，能有效抵抗各种攻击方式。同时，该方法解决了码分多址的使用扩大了信号带宽的问题，保证了各信息源之间不发生串扰。该方法抗噪能力强，能有效抵抗各种攻击方式。同时，该方法解决了码分多址的使用扩大了信号带宽的问题，保证了各信息源之间不发生串扰。该方法抗噪能力强，能有效抵抗各种攻击方式。同时，该方法解决了码分多址的使用扩大了信号带宽的问题，保证了各信息源之间不发生串扰。
