Attacking Reduced Round SHA-256 [PDF]
, 2008 The SHA-256 hash function has started getting attention recently by the cryptanalysis community due to the various weaknesses found in its predecessors such as MD4, MD5, SHA-0 and SHA-1. We make two contributions in this work. First we describe message modification techniques and use them to obtain an algorithm to generate message pairs which collide ...

Carry-based Differential Power Analysis (CDPA) and its Application to Attacking HMAC-SHA-2
Transactions on Cryptographic Hardware and Embedded Systems, 2023 In this paper, we introduce Carry-based Differential Power Analysis (CDPA), a novel methodology that allows for attacking schemes that use arithmetical addition. We apply this methodology to attacking HMAC-SHA-2. We provide full mathematical analysis of

Analysis of Step-Reduced SHA-256 [PDF]
, 2006 This is the first article analyzing the security of SHA-256 against fast collision search which considers the recent attacks by Wang et al. We show the limits of applying techniques known so far to SHA-256. Next we introduce a new type of perturbation vector which circumvents the identified limits.
