Traditional random phase masks (RPMs) are dynamic in double random phase encoding (DRPE). Asymmetric cryptosystems have been proposed because symmetric cryptosystems are vulnerable to several attacks. In this cryptosystem, chaotic Henon map fingerprint masks (CHMFM) are built instead of conventional phase masks. There are several transform domains where the encryption and decryption processes are carried out. The chaotic Henon map, fingerprints, and an asymmetric cryptosystem are the foundations of the suggested system’s security. The fingerprint is shared by the source and the destination. Therefore, in the suggested method, the broadcasting and the organization share the secret keys, which is suitable. Furthermore, fingerprint keys have a strong correlation with both the origin and the destination. To verify the resilience of the suggested asymmetric cryptosystem, numerous numerical simulations and studies have been carried out, including noise analysis, correlation coefficient analysis, occlusion study, sensitivity analysis, etc.
