Optical encryption and encoding techniques are attractive to researchers, because they can optically encrypt an image at high speed. Especially, double random phase encoding (DRPE) is known as a typical optical encryption and encoding method. DRPE encrypts images by random phase modulations in the spatial and Fourier plane. Many researchers have reported the security analysis of DRPE. It is important to investigate the security strength against some attacks, such as known-plaintext attack (KPA). In this paper, we introduce the known-plaintext attack-based analysis of DRPE. DRPE is easy to expand because the optical system of DRPE is simple. Therefore, there are various types of DRPE, such as DRPE based on fractional Fourier transform and Fresnel transform. However, the optical systems are based on coherent light. Therefore, we introduce the proposed incoherent optical system of DRPE. In the future, we expect new applications based on DRPE algorithm for a camera and sensor.
