Collisions for Step-Reduced SHA-256 [PDF]
, 2008 In this article we find collisions for step-reduced SHA-256. We develop a differential that holds with high probability if the message satisfies certain conditions. We solve the equations that arise from the conditions. Due to the carefully chosen differential and word differences, the message expansion of SHA-256 has little effect on spreading the ...

Security Analysis of SHA-256 and Sisters [PDF]
, 2004 This paper studies the security of SHA-256, SHA-384 and SHA-512 against collision attacks and provides some insight into the security properties of the basic building blocks of the structure. It is concluded that neither Chabaud and Joux’s attack, nor Dobbertin-style attacks apply.

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
