Abstract

An incoherent optical cryptosystem based on hybrid wave aberration is proposed in this study. The proposed cryptosystem is designed with different channels to divide the object. In each channel, different wave aberrations are allocated to form the hybrid wave aberration. When the object is imaged by the channel with huge wave aberrations, its corresponding image will be blurry enough to form a ciphertext. Because the different wave aberrations in different channels can be regarded as the key, the proposed optical cryptosystem can achieve multi-key encryption as well as local encryption. The proposed optical cryptosystem enhances the security of incoherent optical cryptosystem through the quantity of keys and the special construction method of ciphertext.
