In this paper, a color image encrypting method based on chaos theory is introduced. Image encryption because of some intrinsic features of images, such as high data volume and high correlation among pixels, the encrypting text is different. For this reason the classic method of encrypting text for this purpose is not high performance. For two reasons, the proposed method compared with other methods with high security. First, use the hyper chaos and the second large of the space key. In the simulation results, various experiments have been conducted to analyze the security of the proposed method.

“…To address this problem, some researchers proposed to use the chaotic maps to generate the random phase mask, and use the chaos parameters to replace the whole phase mask to act as the secret key. For example, Singh et al used the Logistic map, Tent map and Yorke map to generate the phase masks in an FrFT-based DRPE scheme [5]. Sui et al used the Logistic map to generate the phase masks in a GT-based DRPE scheme [6].…”

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.

“…Due to these advantages, chaotic systems have been widely applied to image secure communication. Singh et al [10] propose a new DRPE method using fractional Fourier transform and chaos theory for image encryption, in which random phase masks are generated using iterative chaos functions. Taheri et al [11] proposed a phase mask generation scheme using chaos theory and hash function to enhance the DRPE security.…”
