System approach to disparity estimation [PDF]

open access: yes, 1995
A system approach to disparity estimation using dynamic programming is presented. The four step system can calculate a dense correspondence map between a stereo pair with parallel or nonparallel camera geometry.

Related-Key Differential Cryptanalysis of the Reduced-Round Block Cipher GIFT

open access: yesIEEE Access, 2019
GIFT is a lightweight block cipher that was proposed by Banik et al. at CHES 2017, which is said to be a direct improvement over PRESENT since “that provides a much increased efficiency in all domains (smaller and faster)” and improves the ...

Differential Cryptanalysis and Boomerang Cryptanalysis of LBlock [PDF]

open access: yes, 2013
LBlock is a lightweight block cipher proposed in ACNS 2011. It has a 64-bit block size and 80-bit key size which is the typical parameter setting accepted by most of the recent proposed lightweight block ciphers. It has fast hardware implementation efficiency and it still remains rather secure considering the recent results and the security margin it ...

Improbable differential cryptanalysis [PDF]

open access: yesProceedings of the 6th International Conference on Security of Information and Networks, 2013
Statistical attacks on block ciphers make use of a property of the cipher so that an event occurs with different probabilities depending on whether or not the correct key is used. For instance, differential cryptanalysis [3] and truncated differential cryptanalysis [5] consider characteristics or differentials which show that a particular output ...

Improved conditional differential cryptanalysis [PDF]

open access: yesSecurity and Communication Networks, 2014
AbstractIn lightweight cryptographic primitives, non‐linear feedback shift registers (NFSR) are widely used nowadays. At ASIACRYPT 2010, conditional differential cryptanalysis was proposed to analyze NFSR‐based cryptosystems. To get better result, we propose an improved version of this attack.

Cryptanalysis of an MPEG-Video Encryption Scheme Based on Secret Huffman Tables [PDF]

open access: yes, 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 ...

Quantum differential cryptanalysis to the block ciphers

open access: yes, 2015
Differential cryptanalysis is one of the most popular methods in attacking block ciphers. However, there still some limitations in traditional differential cryptanalysis.

Influence of Non-Linearity on Selected Cryptographic Criteria of 8x8 S-Boxes

open access: yesActa Informatica Pragensia, 2017
The article defines standard criteria used to characterize the cryptographic quality of the S box: regularity, non linearity, autocorrelation, avalanche and immunity against differential cryptanalysis.

Higher-Order Differential-Linear Cryptanalysis of ChaCha Stream Cipher

open access: yesIEEE Access
This paper studies the advanced methodologies of differential cryptanalysis with a particular emphasis on higher-order differentials and higher-order differential-linear cryptanalysis, along with their application to the ChaCha stream cipher.
