Modern Hash Function Construction
This paper discusses modern hash function construction using the NIST SHA-3 competition as a survey of modern hash function construction properties. Three primary hash function designs are identified based on the designs of SHA-3 candidates submitted as part of the NIST SHA-3 competition. These designs are Widepipe, Sponge, and HAsh Iterated FrAmework (HAIFA). Keywordscryptography; hashing; has...
متن کاملSecurity Analysis and Comparison of the SHA-3 Finalists BLAKE, Grøstl, JH, Keccak, and Skein
In 2007, the US National Institute for Standards and Technology announced a call for the design of a new cryptographic hash algorithm in response to the vulnerabilities identified in widely employed hash functions, such as MD5 and SHA-1. NIST received many submissions, 51 of which got accepted to the first round. At present, 5 candidates are left in the third round of the competition. An import...
متن کاملBroad View of Cryptographic Hash Functions
Cryptographic hash function is a function that takes an arbitrary length as an input and produces a fixed size of an output. The viability of using cryptographic hash function is to verify data integrity and sender identity or source of information. This paper provides a detailed overview of cryptographic hash functions. It includes the properties, classification, constructions, attacks, applic...
متن کاملAn FPGA implementation of SHA 3 using keccak function for 512 bit encryption
SHA-3 (Secure hash algorithm-3), originally known as Keccak is a cryptographic hash function selected as the winner of the NIST hash function competition. Hash functions have many applications in cryptography mainly in digital signatures and message authentication codes and in network security. Implementation of the main building block (compression function) for five different SHA-3 candidates ...
متن کاملLSH: A New Fast Secure Hash Function Family
Since Wang’s attacks on the standard hash functions MD5 and SHA-1, design and analysis of hash functions have been studied a lot. NIST selected Keccak as a new hash function standard SHA-3 in 2012 and announced that Keccak was chosen because its design is different from MD5 and SHA-1/2 so that it could be secure against the attacks to them and Keccak’s hardware efficiency is quite better than o...
متن کاملCryptanalysis of the SHA-3 candidates EnRUPT and SHAMATA
In this talk, we review the successful cryptanalysis of two cryptographic hash functions, EnRUPT and SHAMATA. Both were submitted as candidates to the NIST SHA-3 competition.
