A CHAOS-BASED CRYPTOGRAPHIC HASH FUNCTION FOR MESSAGE AUTHENTICATION

International Journal of Bifurcation and Chaos in Applied Sciences and Engineering, 2005
In this paper, a chaos-based cryptographic hash function is proposed for message authentication where a fixed length message digest can be generated from any messages with arbitrary length. The compression function in-use is developed according to the diffusion and confusion properties of a novel high-dimensional discrete chaotic map.

Requirements for cryptographic hash functions

Computers & Security, 1992
We give a comprehensive discussion of and structure for the quality requirements good cryptographic hash functions should fulfil. Functional requirements like contraction of the input and fast calculation are ordered by priority in the algorithm design and implementation process.

Cryptographic hash functions

European Transactions on Telecommunications, 1994
AbstractHash functions were introduced in cryptology in the late seventies as a tool to protect the authenticity of information. Soon it became clear that they were a very useful building block to solve other security problems in telecommunication and computer networks.

The NIST Cryptographic Workshop on Hash Functions

IEEE Security & Privacy Magazine, 2006
In light of recent breakthroughs on the cryptanalysis of hash functions, the US National Institute for Standards and Technology (NIST) organized a workshop to solicit input on the current status of the Secure Hash Algorithm-1 (SHA-1) family of hash functions.

Cryptographic Hash Function

2015
Cryptographic hash function verifies data integrity and sender identity or source of information. The task is accomplished by taking a variable bit patterns as an input then produces a fixed bit patterns of output. This chapter provides a detailed overview to include classification, properties, constructions, attacks, applications and an overview of a ...

Cryptographic Hash Functions

2020
Don't get intimidated by the title of this chapter. The theory of cryptographic hash functions is not particularly abstruse. What is difficult is the construction of these functions from scratch. However, we need not concern ourselves with this aspect of the mathematical theory since most programming language libraries provide us with a good selection ...

Performance and Security Tradeoffs in Cryptographic Hash Functions

International Journal of Interdisciplinary Telecommunications and Networking, 2020
A cryptographic hash function is an important component used in many applications, such as blockchain, authentication, data integrity, and digital signature. With the rapid increase in usage of mobile devices, more attention goes towards the tradeoffs between performance and security of cryptographic hash functions on mobile devices due to their ...

VLSI Characterization of the Cryptographic Hash Function BLAKE

IEEE Transactions on Very Large Scale Integration (VLSI) Systems, 2011
Cryptographic hash functions are used to protect information integrity and authenticity in a wide range of applications. After the discovery of weaknesses in the current deployed standards, the U.S. Institute of Standards and Technology started a public competition to develop the future standard SHA-3, which will be implemented in a multitude of ...
