Abstract

In this research process, in order to improve the ability of interference-based optical image encryption system to resist chosen plaintext attacks, we propose an optical pseudo-image encryption algorithm to enhance the correlation of plaintext. In this work, we introduce an addictional key, which is highly correlated with the secret image. The key can dynamically update the random phase plate and break the linear relationship between the input and output of the optical encryption system, so that the system will not be cracked by chosen plaintext attacks. Furthermore, the number of keys is reduced through improved sine chaos mapping, so that the encryption system can reduce the amount of key storage data while improving the security of the system.
