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 ...

Ramanujan graphs in cryptography [PDF]

, 2018
In this paper we study the security of a proposal for Post-Quantum Cryptography from both a number theoretic and cryptographic perspective. Charles-Goren-Lauter in 2006 [CGL06] proposed two hash functions based on the hardness of finding paths in ...

Performance of the most common non-cryptographic hash functions [PDF]

Software: Practice and Experience, 2013
Non-cryptographic hash functions (NCHFs) have an immense number of applications, ranging from compilers and databases to videogames and computer networks. Some of the most important NCHF have been used by major corporations in commercial products. This practical success demonstrates the ability of hashing systems to provide extremely efficient searches

Cryptographic hash functions for image processing [PDF]

, 2021
In this paper, a novel algorithm based on hash function for image cryptography is proposed. In this algorithm, the key idea is to encrypt half of the image using data from the second half of the image and then apply it to each other. This scheme can achieve high sensitivity, high complexity, and high security.

ON THE UNIVERSAL TREE MODE OF HASH CODE GENERATION

Современные информационные технологии и IT-образование, 2018
Classical approaches to the construction of hash function modes, based on the using of iterative procedures, do not allow efficient processing of large amounts of data and can’t be adapted to parallel computing architectures.

Keyed Parallel Hash Algorithm Based on Multiple Chaotic Maps (KPHA-MCM)

IEEE Access, 2021
Hash functions are considered as the core of cryptography, which are the basic technique used for data security. Cryptographic hash functions also can be used to achieve the integrity of large data such as the data stored in a hard disk and set of ...

Transparent code authentication at the processor level [PDF]

, 2009
The authors present a lightweight authentication mechanism that verifies the authenticity of code and thereby addresses the virus and malicious code problems at the hardware level eliminating the need for trusted extensions in the operating system.

Bad Directions in Cryptographic Hash Functions

, 2015
A 25-gigabyte “point obfuscation” challenge “using security parameter 60” was announced at the Crypto 2014 rump session; “point obfuscation” is another name for password hashing. This paper shows that the particular matrix-multiplication hash function used in the challenge is much less secure than previous password-hashing functions are believed to be.

Formally based semi-automatic implementation of an open security protocol [PDF]

, 2012
International audienceThis paper presents an experiment in which an implementation of the client side of the SSH Transport Layer Protocol (SSH-TLP) was semi-automatically derived according to a model-driven development paradigm that leverages formal ...
