Optical vortex beam has gained much attention in the field of information processing because its inherent features, such as infinite number orthogonal modes. In this paper, we demonstrate optical image encryption based on deoxyribonucleic acid (DNA) encoding rule through vortices. scheme, two levels security are achieved; first level, an input is encrypted using equal modulus decomposition well phase truncation and reservation approach. Thus, obtained encoded into a DNA sequence according to existing then exclusive-OR operation applied with random key order obtain ciphertext. second level security, beams different modes arranged form lattices. This type overcomes tedious task manually also enhances space and, hence, security. Simulation experimental results support efficacy proposed scheme.

In recent years, the security of audio data has become paramount in terms personal information, national security, and forensic evidence. However, most reported systems use digital algorithms lack their implementation optical domain, which can provide better due to physical keys high speed. addition, recently developed phase-encoded encryption schemes domain have quality limitations precise wavefront measurement control. Perfect experimental alignment achieve good retrieved is very challenging, no voice been reported. This work introduces a robust scheme using polarization property light beam. Initially, one-dimensional (1D) combined with random dataset acts as an key converts it 1D cipher audio, transformed into two-dimensional (2D) cipher-audio map. Subsequently, this fragmented several 2D segments, are then encoded beam binary states. An arbitrary sequence maintained during encoding segments The demonstrated technique non-interferometric method, decryption be achieved through intensity recording only.
