Visualising Sha[2] in Abelian surfaces [PDF]

open access: hybridMathematics of Computation, 2004
Given an elliptic curve E1 over a number field and an element s in its 2-Selmer group, we give two different ways to construct infinitely many Abelian surfaces A such that the homogeneous space representing s occurs as a fibre of A over another elliptic curve E2.

SHA-2 Acceleration Meeting the Needs of Emerging Applications: A Comparative Survey [PDF]

open access: goldIEEE Access, 2020
While SHA-2 is a ubiquitous cryptographic hashing primitive, its role in emerging application domains, e.g. blockchains or trusted IoT components, has made the acceleration of SHA-2 very challenging due to new stringent classes of requirements ...

Study Security Cloud with SHA-2 Algorithm

open access: gold, 2023
This study explores the relationship between cloud computing and security, concentrating on the use of the SHA-2 cryptographic algorithm. Due to the distributed and shared nature of cloud settings, cloud computing has transformed how information and services are accessed and provided. However, it has also created new security issues.

Multi-mode operator for SHA-2 hash functions [PDF]

open access: bronzeJournal of Systems Architecture, 2006
We propose an improved implementation of the SHA-2 hash family, with minimal operator latency and reduced hardware requirements. We also propose a high frequency version at the cost of only two cycles of latency per message. Finally we present a multi-mode architecture able to perform either a SHA-384 or SHA-512 hash or to behave as two independent SHA-

Preimages for Step-Reduced SHA-2 [PDF]

open access: bronze, 2009
In this paper, we present preimage attacks on up to 43-step SHA-256 (around 67% of the total 64 steps) and 46-step SHA-512 (around 57.5% of the total 80 steps), which significantly increases the number of attacked steps compared to the best previously published preimage attack working for 24 steps.

Carry-based Differential Power Analysis (CDPA) and its Application to Attacking HMAC-SHA-2

open access: diamondTransactions 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
