On Known-Plaintext Attacks to a Compressed Sensing-based Encryption: A Quantitative Analysis [PDF]
IEEE Transactions on Information Forensics and Security, 2015 Despite the linearity of its encoding, compressed sensing may be used to provide a limited form of data protection when random encoding matrices are used to produce sets of low-dimensional measurements (ciphertexts).

Adaptive Color Image Encryption Scheme Based on Multiple Distinct Chaotic Maps and DNA Computing
Mathematics, 2022 In this paper, we propose an adaptive encryption scheme for color images using Multiple Distinct Chaotic Maps (MDCM) and DNA computing. We have chosen three distinct chaotic maps, including a 2D-Henon map, a Tent map, and a Logistic map, to separately ...

Improved Parameter Estimates for Correlation and Capacity Deviates in Linear Cryptanalysis
IACR Transactions on Symmetric Cryptology, 2017 Statistical attacks form an important class of attacks against block ciphers. By analyzing the distribution of the statistics involved in the attack, cryptanalysts aim at providing a good estimate of the data complexity of the attack.

Cryptanalysis of an MPEG-Video Encryption Scheme Based on Secret Huffman Tables [PDF]
, 2007 This paper studies the security of a recently-proposed MPEG-video encryption scheme based on secret Huffman tables. Our cryptanalysis shows that: 1) the key space of the encryption scheme is not sufficiently large against divide-and-conquer (DAC) attack ...
