A Novel Image Encryption Scheme Based on Single Random Phase Encoding and Chaos

Abstract

In this paper, a novel image encryption scheme based on single random phase encoding and chaos is proposed. In the proposed scheme, the random phase mask is generated by Henon map, and the chaos parameters of Henon map can replace the whole phase mask to serve as the secret keys. Thus the management and transmission of secret keys are more convenient in the proposed scheme. Additionally, the proposed scheme contains only one random phase mask, which makes it more efficient and concise to implement. The performance of the proposed scheme has been demonstrated by extensive experiments.
