A Coarse Grained Reconfigurable Architecture for SHA-2 Acceleration

2022 IEEE International Parallel and Distributed Processing Symposium Workshops (IPDPSW), 2022
The development of high-speed SHA-2 hardware with high flexibility is urgently needed because SHA-2 functions are widely employed in numerous fields, from loT devices to cryp-to currency.

A New Message Expansion Structure for Full Pipeline SHA-2

IEEE Transactions on Circuits and Systems I: Regular Papers, 2021
Once there are constant or infrequently changed bits (COIBs) in two adjacent input messages of SHA-2, the switching power of input messages data registers (IMD-REGs) used for COIBs will disappear.

Quantum Implementation and Analysis of SHA-2 and SHA-3

IEEE Transactions on Emerging Topics in Computing
Quantum computers have the potential to solve a number of hard problems that are believed to be almost impossible to solve by classical computers. This observation has sparked a surge of research to apply quantum algorithms against the cryptographic ...

Keyed/Unkeyed SHA-2

Journal of Discrete Mathematical Sciences and Cryptography, 2003
Abstract In FIPS 180–2, NIST published SHA-2 as a new version of secure hash algorithm. SHA-2 offers four secure hash algorithms including SHA-1, SHA-256, SHA-384, and SHA-512. In other words, SHA-2 may have outputs 160, 256, 384, or 512 bits of message digest. However, SHA-2 algorithm uses fixed and predefined parameters in execution.

Implementation and comparison of the functions of building blocks in SHA-2 family used in secured cloud applications

Journal of Discrete Mathematical Sciences and Cryptography, 2019
A Secure hash algorithm is grounded on the principles of message digest algorithms that are used in the design of the algorithms like MD4 and MD5. The main application of this algorithm is that it can be used in security applications for authentication ...

Keccak und der SHA-2

Datenschutz und Datensicherheit - DuD, 2013
Wie beim DES-Nachfolger AES schrieb das US-amerikanische NIST 2007 einen offentlichen Wettbewerb um die Nachfolge des Hashverfahrens SHA-2 aus. Im Oktober 2012 fiel die Wahl auf Keccak. Die Autoren stellen den Hashalgorithmus vor, beschreiben eine Smartcard-Implementierung und stellen das Verfahren dem „amtierenden“ SHA-2-Standard gegenuber.

SHA-2 hardware core for virtex-5 FPGA

2015 IEEE 12th International Multi-Conference on Systems, Signals & Devices (SSD15), 2015
Hash functions play an important role in modern cryptography. They are widely used to provide services of data integrity and authentication. The hash algorithms are based on performing a number of complex operations on the input data that require a significant amount of computing resources especially when the input data are huge.

First Full-Fledged Side Channel Attack on HMAC-SHA-2

International Workshop on Constructive Side-Channel Analysis and Secure Design, 2021
Side-channel attacks pose a threat to cryptographic algorithms. Hash functions, in particular those from the SHA-2 family, can also be an interesting target if some of their inputs are secret. HMAC is an important use case of a hash function, in which the input is partially secret and thus unknown to the attacker.
