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 ...

A Family of Fast Syndrome Based Cryptographic Hash Functions [PDF]
, 2005 Recently, some collisions have been exposed for a variety of cryptographic hash functions~\cite{WFLY04} including some of the most widely used today. Many other hash functions using similar constrcutions can however still be considered secure. Nevertheless, this has drawn attention on the need for new hash function designs. In this article is presented

Cryptographic Hash Function using Cellular Automata [PDF]
International Journal of Computer Applications Technology and Research, 2016 Since two distinct messages are extremely unlikely to generate identical message digests, one can use this property of cryptographic hash functions to detect when a message has been altered. If one takes a binary file and computes a digest of the file, one can record this baseline digest. In the future, the digest can be recomputed on the file.

Cryptographic Hash Functions from Expander Graphs [PDF]
Journal of Cryptology, 2007 We propose constructing provable collision resistant hash functions from expander graphs in which finding cycles is hard. As examples, we investigate two specific families of optimal expander graphs for provable collision resistant hash function constructions: the families of Ramanujan graphs constructed by Lubotzky-Phillips-Sarnak and Pizer ...

A Survey: Cryptographic Hash Functions for Digital Stamping
Journal of Southwest Jiaotong University, 2019 The current study aims to examine a general overview of the application of hash functions in cryptography and study the relationships between cryptographic hash functions and uses of the digital signature. Functions of the cryptographic hash are an important tool applied in several sections of data security, and application of hash function is common ...
