MD5 is one of the most widely used cryptographic hash functions nowadays. It was
designed in 1992 as an improvement of MD4, and its security was widely studied since then …

MD4 is a hash function developed by Rivest in 1990. It serves as the basis for most of the
dedicated hash functions such as MD5, SHAx, RIPEMD, and HAVAL. In 1996, Dobbertin …

We expand a previous result of Dean [Dea99] to provide a second preimage attack on all n-
bit iterated hash functions with Damgård-Merkle strengthening and n-bit intermediate states …

This paper reconsiders the established Merkle-Damgård design principle for iterated hash
functions. The internal state size w of an iterated n-bit hash function is treated as a security …

The continued growth of both wired and wireless communications has triggered the
revolution for the generation of new cryptographic algorithms. SHA-2 hash family is a new …

Hash functions—or rather cryptographic hash functions—constitute an important primitive
necessary in many cryptographic applications. They are used to compress messages—to be …

Hardware implementation aspects of the MD5 hash algorithm are discussed in this paper. A
general architecture for MD5 is proposed and several implementations are presented. An …

From the Rosetta Stone to public-key cryptography, the art and science of cryptology has
been used to unlock the vivid history of ancient cultures, to turn the tide of warfare, and to …

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 …

In this paper, we propose a 2/3-rate double length compression function and study its
security in the black-box model. We prove that to get a collision attack for the compression …
