Transactions on Cryptographic Hardware and Embedded SystemsThe standardization of the hash-based digital signature scheme SPHINCS+ proceeds faster than initially expected. This development seems to be welcomed by practitioners who appreciate the high confidence in SPHINCS+’s security assumptions and its ...

Rotational cryptanalysis of round-reduced Keccak [PDF]
, 2013 In this paper we attack round-reduced Keccak hash function\ud with a technique called rotational cryptanalysis. We focus on Keccak variants proposed as SHA-3 candidates in the NIST’s contest for a new standard of cryptographic hash function.

Cryptanalysis of 1-Round KECCAK [PDF]
, 2017 In this paper, we give the first pre-image attack against 1- round KECCAK-512 hash function, which works for all variants of 1- round KECCAK. The attack gives a preimage of length less than 1024 bits by solving a system of 384 linear equations.

Throughput Optimum Architecture of KECCAK Hash Function
International Journal of Computer and Electrical Engineering, 2012 Because of the weakening of the widely-used SHA-1 hash algorithm and concerns over the similarly-structured algorithms of the SHA-2 family; the US NIST has initiated the SHA-3 contest in order to select a suitable drop-in replacement. In this paper we use the unrolling method to describe the high-speed hardware implementation of the SHA-3 hash function

New Attacks on Keccak-224 and Keccak-256 [PDF]
, 2011 The Keccak hash function is one of the five finalists in NIST\u27s SHA-3 competition, and so far it showed remarkable resistance against practical collision finding attacks: After several years of cryptanalysis and a lot of effort, the largest number of ...

Tanda tangan Digital Menggunakan Algoritme Keccak dan RSA
Jurnal Nasional Teknik Elektro dan Teknologi Informasi, 2016 Just like conventional signatures, digital signatures can be used to prove the authenticity of a document in digital form. In addition, digital signatures can also be used to prove the validity of the author of the document, so that the author of the ...

A Lightweight Hash Function Based on Enhanced Chaotic Map Algorithm(Keccak)
Iraqi Journal of Computer, Communication, Control and System Engineering, 2022 Cryptography is a security strategy that prevents disclosure of the information while it is transit, in storage, or both. There are a variety of methods for maintaining data security, including utilizing light weight speed algorithms for encryption and parameter validation.
