Hyperchaotic hashing: a chaotic hash function based on 2D linear cross-coupled map with parallel feedback structure [PDF]

Scientific Reports
Chaotic systems have been widely employed in constructing hash functions because of their nonlinear characteristics. Nonetheless, some chaotic hash functions are intricately designed, significantly increasing their computational overhead, and some can ...

Cryptographic Hash Functions: Theory and Practice [PDF]

, 2010
Cryptographic hash functions are an essential building block for security applications. Until 2005, the amount of theoretical research and cryptanalysis invested in this topic was rather limited. From the hundred designs published before 2005, about 80% was cryptanalyzed; this includes widely used hash functions such as MD4 and MD5.

SMASH – A Cryptographic Hash Function [PDF]

, 2005
This paper presents a new hash function design, which is different from the popular designs of the MD4-family. Seen in the light of recent attacks on MD4, MD5, SHA-0, SHA-1, and on RIPEMD, there is a need to consider other hash function design strategies. The paper presents also a concrete hash function design named SMASH.

Anti-disassembly using Cryptographic Hash Functions [PDF]

Journal in Computer Virology, 2006
Computer viruses sometimes employ coding techniques intended to make analysis difficult for anti-virus researchers; techniques to obscure code to impair static code analysis are called anti-disassembly techniques. We present a new method of anti-disassembly based on cryptographic hash functions which is portable, hard to analyze, and can be used to ...
