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.

New Records in Collision Attacks on SHA-2 [PDF]

Journal of Cryptology
The SHA-2 family including SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224 and SHA512/256 is a U.S. federal standard pub- lished by NIST. Especially, there is no doubt that SHA-256 is one of the most important hash functions used in real-world ...

Turbo SHA-2. [PDF]

IACR Cryptol. ePrint Arch., 2007
In this paper we describe the construction of Turbo SHA-2 family of cryptographic hash functions. They are built with design components from the SHA-2 family, but the new hash function has three times more chaining variables, it is more robust and ...

Dynamic SHA-2. [PDF]

IACR Cryptol. ePrint Arch., 2008
In this paper I describe the construction of Dynamic SHA-2 family of cryptographic hash functions. They are built with design components from the SHA-2 family, but I use the bits in message as parameters of function G, R and ROTR operation in the new ...

On Corrective Patterns for the SHA-2 Family. [PDF]

IACR Cryptol. ePrint Arch., 2004
The Secure Hash Standard (SHS) [3] includes hashing algorithms denoted SHA-n, (n in {224, 256, 384, 512}) for producing message digests of length n.

In-memory realization of SHA-2 using ReVAMP architecture

2021 34th International Conference on VLSI Design and 2021 20th International Conference on Embedded Systems (VLSID), 2021
Emerging non-volatile memory (NVM) technologies with computation capabilities have heralded a new era of non- Von Neumann computing models. Redox-based Resistive RAM (ReRAM) is a prominent NVM technology, which offers high density, low leakage power and ability to perform functionally complete set of Boolean operations.

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.

New Collision attacks Against Up To 24-step SHA-2. [PDF]

IACR Cryptol. ePrint Arch., 2008
In this work, we provide new and improved attacks against 22, 23 and 24-step SHA-2 family using a local collision given by Sanadhya and Sarkar (SS) at ACISP \u2708. The success probability of our 22-step attack is 1 for both SHA-256 and SHA-512.
