“…( 1), the temporal resolution of the reconstruction image M (t) is determined by the coherence time of the randomized light source (τ l ) and the temporal resolution of D f , which is independent of the temporal resolution of the detector after the object. These features make TGI a potential technique for many applications, such as computational temporal imaging [36], optical secure imaging [37,38], detection efficiency evaluation of SPDs [39], and wavelength-conversion imaging [40].…”

Quantum key distribution (QKD) can generate secure key bits between remote users with quantum mechanics. However, the gap between the theoretical model and practical realizations gives eavesdroppers opportunities to intercept secret key. The most insidious attacks, known as quantum hacking, are the ones with no significant discrepancy of the measurement results using side-channel loopholes of QKD systems. Depicting full-time-scale characteristics of the quantum signals, the quantum channel, and the QKD system can provide legitimate users extra capabilities to defeat malicious attacks. For the first time, we propose the method exploring temporal ghost imaging (TGI) scheme to perceive quantum hacking with temporal fingerprints and experimentally verify its validity. The scheme presents a common approach to promote QKD's practical security from a new perspective of signals and systems.

“…However, a notorious cryptographic application of these systems is chaos based image encryption algorithms [6], [28], [32], [35]. The researchers claimed that new image encryption algorithms could be designed using the strong theoretical relationship between chaos and cryptography [1]- [3], [7]- [17], [19], [8], [24]- [26], [30], [31], [36]. However, this strong theoretical relationship has led to the emergence of unsecure designs due to misuse and lack of analysis.…”

Robust protocols are needed to create a secure computing system. Protocols designed without considering various design criteria result in many vulnerabilities. Security has many aspects. The slightest defect in the design processes affects the whole system security. Chaos based image encryption algorithms have become increasingly popular in the recent period. However, most of these algorithms are often based on cryptanalysis driven design technique. Therefore, the security of these algorithms is doubtful as long as the threat of attack continues. In this paper, attention has been drawn to this problem. First, the security problems of two different chaos based image encryption algorithms have been analyzed. In the second analyzed study, the security problem of the first analyzed study has been examined and a new improved version has been published. The common point of these two analyzed studies is that both the original and the improved algorithm are designed on the basis of the cryptanalysis has driven design approach. In other words, the security of these two algorithms is still doubtful. In this study, security problems have been shown for both algorithms and the encryption algorithms have been broken. In the second part of the study, a road map based on a provable secure driven design approach is presented for future studies to avoid such problems.

“…Optical encryption, authentication and watermarking systems [1][2][3] can be constructed for information security applications, with advantages such as multi-dimensional parallel processing capabilities, fast processing speed and direct processing of physical objects without digitalization. In previous works, an image encryption system can be physically implemented with various types of optical imaging systems, including but not limited to double random phase encoding (DRPE) [4], holography [5,6], integral imaging [7][8][9], ptychography [10,11], and single-pixel imaging [12][13][14][15][16][17][18][19][20][21]. In these systems, the plaintext image is converted to a light field, which is optically transformed into a ciphertext light field with certain physical encryption keys (e.g.…”

“…For other types of optical encryption systems such as DRPE [4], various implementations of encryption systems [24][25][26][27][28] and various types of cryptanalysis [29][30][31][32][33][34][35] including CPA, KPA and COA have been extensively investigated. However, for encrypted SPI, many works have been conducted on the design of encryption systems [12][13][14][15][16][17][18][19][20][21] since the earliest attempt [12] but little cryptanalysis has been investigated previously. As far as the author knows, only one such work [36] can be found, in which some CPA methods are proposed.…”

Known-Plaintext Attack and Ciphertext-Only Attack for Encrypted Single-Pixel Imaging

et al. 2019

In many previous works, a single-pixel imaging (SPI) system is constructed as an optical image encryption system. Unauthorized users are not able to reconstruct the plaintext image from the ciphertext intensity sequence without knowing the illumination pattern key. However, little cryptanalysis about encrypted SPI has been investigated in the past. In this work, we propose a known-plaintext attack scheme and a ciphertext-only attack scheme to an encrypted SPI system for the first time. The known-plaintext attack is implemented by interchanging the roles of illumination patterns and object images in the SPI model. The ciphertext-only attack is implemented based on the statistical features of single-pixel intensity values. The two schemes can crack encrypted SPI systems and successfully recover the key containing correct illumination patterns.
