This paper gives a survey on cryptographic hash functions. It gives an overview of all types
of hash functions and reviews design principals and possible methods of attacks. It also …

Hash 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 …

This paper describes the state of the art for cryptographic hash functions. Different definitions
are compared, and the few theoretical results on hash functions are discussed. A brief …

Recent years have witnessed an exceptional research interest in cryptographic hash
functions, especially after the popular attacks against MD5 and SHA-1 in 2005. In 2007, the …

We consider basic notions of security for cryptographic hash functions: collision resistance,
preimage resistance, and second-preimage resistance. We give seven different definitions …

The most common way of constructing a hash function (eg, SHA-1) is to iterate a
compression function on the input message. The compression function is usually designed …

Constructions for hash functions based on a block cipher are studied where the size of the
hashcode is equal to the block length of the block cipher and where the key size is …

In this paper, we study issues related to the notion of “secure” hash functions. Several
necessary conditions are considered, as well as a popular sufficient condition (the so-called …
