基于符合测量机制的光学信息保护

Optical Information Protection Based on Coincidence Measurement

提出了一种基于符合测量机制的光学信息保护方法。发送方选择一定的载波信号将待传输的信息加载在待成像的物体上,接收方进行符合测量,并根据双方之间的协议从测量得到的物体的空间分布信息中解密出信息。计算机仿真结果表明,该方案能够成功实现信息的保护,具有良好的安全性。

This paper introduces a scheme based on coincidence measurement to realize optical information protection between two communicators. The sender chooses appropriate carrier signals to attach important information to the object in the test arm. The receiver retrieves the information from the coincidence measurement according to an agreement between the sender and the receiver. The results of numerical computing show that our scheme can protect the information successfully and has a good performance on secrecy.
