Study of an encryption system based on compressive temporal ghost imaging with a chaotic laser
Abstract
A chaotic laser has good time controllable randomness and second-order temporal relevance. It is widely used in chaotic encryption. Temporal ghost imaging is a non-local imaging method, and its characteristics determine that it has strong application prospects in encryption. In this paper, temporal ghost imaging with a chaotic laser is used in optical encryption. The excellent cryptographic properties of the chaotic laser and the non-linear encryption of ghost imaging are combined. The simulation results show that this encryption system has high security and anti-noise capabilities.
