Analysis of an Optimal Fault Attack on the LED-64 Lightweight Cryptosystem
IEEE Access, 2019 This paper presents an optimal method for recovering the secret keys of the light encryption device (LED) by combining the impossible differential fault attack with the algebraic differential fault attack. The proposed optimal method effectively improves

Breaking an image encryption algorithm based on chaos
, 2011 Recently, a chaos-based image encryption algorithm called MCKBA (Modified Chaotic-Key Based Algorithm) was proposed. This paper analyzes the security of MCKBA and finds that it can be broken with a differential attack, which requires only four chosen ...

Cryptanalysis of two chaotic encryption schemes based on circular bit shift and XOR operations [PDF]
, 2007 Recently two encryption schemes were proposed by combining circular bit shift and XOR operations, under the control of a pseudorandom bit sequence (PRBS) generated from a chaotic system. This paper studies the security of these two encryption schemes and

Towards Key-recovery-attack Friendly Distinguishers: Application to GIFT-128
IACR Transactions on Symmetric Cryptology, 2021 When analyzing a block cipher, the first step is to search for some valid distinguishers, for example, the differential trails in the differential cryptanalysis and the linear trails in the linear cryptanalysis.

The (related-key) impossible boomerang attack and its application to the AES block cipher [PDF]
, 2010 The Advanced Encryption Standard (AES) is a 128-bit block cipher with a user key of 128, 192 or 256 bits, released by NIST in 2001 as the next-generation data encryption standard for use in the USA. It was adopted as an ISO international standard in 2005.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction Adult‐onset Still's disease (AOSD) complicated by macrophage activation syndrome (MAS) carries substantial mortality. The role of therapeutic plasma exchange (TPE) remains uncertain. Methods We retrospectively analyzed patients with AOSD‐MAS treated with TPE at a single‐center.
