TLDR
This paper will describe attacks on MD4, MD5 and RIPEMD, and discuss the design and security of the hash functions SHA-1 andRIPEMD-160 which are included in the new standard ISO/IEC 10118-3.Abstract:
Cryptographic hash functions are an important building block for a wide range of applications such as the authentication of information, digital signatures and the protection of pass-phrases. The most popular hash functions are the custom designed iterative hash functions from the MD4 family. Over the years various results on the cryptanalysis of these functions have become available and this paper intends to summarize these results and their impact. We will describe attacks on MD4, MD5 and RIPEMD, and discuss the design and security of the hash functions SHA-1 and RIPEMD-160 which are included in the new standard ISO/IEC 10118-3.read more

An analysis of compare-by-hash
TL;DR: Comparison-by-hash decides whether two blocks are identical to each other by comparing their hash values, using a collision-resistant hash such as SHA-1[5].

ADMAD: Application-Driven Metadata Aware De-duplication Archival Storage System
TL;DR: ADMAD is proposed: an application-driven metadata aware de-duplication archival storage system, which makes use of certain meta-data information of different levels in the I/O path to direct the file partitioning into more meaningful data chunks (MC) to maximally reduce the inter-file level duplications.

R-ADMAD: high reliability provision for large-scale de-duplication archival storage systems
TL;DR: Experimental results show that R-ADMAD can provide the same storage utilization as RAID-like schemes, but comparable reliability to replication based schemes with much more redundancy.

Semantic Data De-duplication for archival storage systems
TL;DR: In this article, semantic data de-duplication (SDD) is proposed, which makes use of the semantic information in the I/O path (such as file type, file format, application hints and filesystem metadata) of the archival files to direct the dividing a file into semantic chunks (SC).

The MD5 Message-Digest Algorithm
TL;DR: This document describes the MD5 message-digest algorithm, which takes as input a message of arbitrary length and produces as output a 128-bit "fingerprint" or "message digest" of the input.

Differential Cryptanalysis of the Data Encryption Standard
Eli Biham,Adi Shamir +1 more
TL;DR: This book introduces a new cryptographic method, called differential cryptanalysis, which can be applied to analyze cryptosystems, and describes the cryptanalysis of DES, deals with the influence of its building blocks on security, and analyzes modified variants.

The MD4 Message-Digest Algorithm
TL;DR: The MD4 message digest algorithm takes an input message of arbitrary length and produces an output 128-bit "fingerprint" or "message digest", in such a way that it is (hopefully) computationally infeasible to produce two messages having the same message digest, or to produce any message having a given prespecified target message digest.

RIPEMD-160: A Strengthened Version of RIPEMD
TL;DR: A new version of RIPEMD with a 160-bit result is proposed, as well as a plug-in substitute for RIPEMd with a 128- bit result, and the software performance of several MD4-based algorithms is compared.
