“…In particular, efficient hierarchical chaotic image encryption (HCIE) algorithm was analyzed in detail and they concluded that the security of the HCIE against ciphertext-only attack was overestimated. Cheng et al [44] proposed a security enhanced double random phase-amplitude encryption (DRPAE) by adding an undercover amplitudemodulating operation in the Fourier domain. They also demonstrated that the DRPAE can resist the traditional (KPA).…”

Abstract. We propose an optical security technique for image encryption using triple random phase encoding (TRPE). In the encryption process, the original image is first double random phase encrypted. The obtained function is then multiplied by a third random phase key in the output plane, to enhance the security level of the encryption process. This method reduces the vulnerability to certain attacks observed when using the conventional double random phase encoding (DRPE). To provide the security enhancement of the proposed TRPE method, three attack cases are discussed: Chosen-plaintext attacks (CPA), Known-plaintext attacks (KPA) and chosen-ciphertext attacks (CCA). Numerical results are presented to demonstrate feasibility and effectiveness of the proposed method. Compared with conventional DRPE, the proposed encryption method can provide an effective alternative and has enhanced security features against the above-mentioned attacks.

“…Since the double-random phase encryption (DRPE) algorithm was proposed by Refregier and Javidi in 1995 [1], it has been widely used in the fields of image authentication, hiding, encryption, and watermarking [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. This algorithm can be implemented quickly due to its parallel property.…”

“…To make up for the deficiency of DRPE in the Fourier domain, many new methods were proposed [12][13][14][22][23][24][25][26]. In [26], W. Chen and X. Chen used only phase information of an encrypted image resulting from DRPE in the Fourier domain to enhance the security of DRPE.…”

The double-random phase encryption (DRPE) algorithm is a robust technique for image encryption, due to its high speed and encoding a primary image to stationary white noise. Recently it was reported that DRPE in the Fresnel domain can achieve a better avalanche effect than that in Fourier domain, which means DRPE in the Fresnel domain is much safer, to some extent. Consequently, a method based on DRPE in the Fresnel domain would be a good choice. In this paper we present an image-authentication method which uses only partial phase information from a double-random-phase-encrypted image in the Fresnel domain. In this method, only part of the phase information of an image encrypted with DRPE in the Fresnel domain needs to be kept, while other information like amplitude values can be eliminated. Then, with the correct phase keys (we do not consider wavelength and distance as keys here) and a nonlinear correlation algorithm, the encrypted image can be authenticated. Experimental results demonstrate that the encrypted images can be successfully authenticated with this partial phase plus nonlinear correlation technique.
