A cryptology protocol for key distribution using phase and intensity fluctuation is proposed. It provides ways to detect the extent of eavesdropping. Detecting test factors and system design rules are suggested and the performances are analyzed for various signal keyings and cryptofunctions. It has a wide range of implementations, including the use of additive white Gaussian noise, background noise, and polarization modification in wire/wireless and optical communications.

Synchronized Sequence

In this paper on strong white Gaussian noise background based on discriminant analysis theory, we mainly adopt synchronized sequence measurements of PMU to search for laws of electrical quantities marked changes. We have developed a method to quickly and accurately discriminate fault components and fault sections. The research has shown that the fault discrimination by discriminant analysis theory is effective and reliable. Under the interference of strong random white Gaussian noise, discriminant analysis still has high redundancy.
