Designing Two Secure Keyed Hash Functions Based on Sponge Construction and the Chaotic Neural Network. [PDF]
Entropy (Basel), 2020 In this paper, we propose, implement, and analyze the structures of two keyed hash functions using the Chaotic Neural Network (CNN). These structures are based on Sponge construction, and they produce two variants of hash value lengths, i.e., 256 and 512

Deep Cross-Modal Hashing with Hashing Functions and Unified Hash Codes Jointly Learning [PDF]
arXiv, 2019 Due to their high retrieval efficiency and low storage cost, cross-modal hashing methods have attracted considerable attention. Generally, compared with shallow cross-modal hashing methods, deep cross-modal hashing methods can achieve a more satisfactory performance by integrating feature learning and hash codes optimizing into a same framework ...

Synthetic and real data sets for benchmarking non-cryptographic hash functions. [PDF]
Data Brief, 2019 The overall assessment of non-cryptographic functions is very complex and there is not a widely used benchmark. These data have been collected and created as a benchmark for testing non-cryptographic hash functions.

A Hash of Hash Functions [PDF]
arXiv, 2003 In this paper, we present a general review of hash functions in a cryptographic sense. We give special emphasis on some particular topics such as cipher block chaining message authentication code (CBC MAC) and its variants. This paper also broadens the information given in some well known surveys, by including more details on block-cipher based hash ...

The Usefulness of Multilevel Hash Tables with Multiple Hash Functions in Large Databases [PDF]
Ann. Univ. Tibiscus Comp. Sci. Series VII(2009),11-20, 2009 In this work, attempt is made to select three good hash functions which uniformly distribute hash values that permute their internal states and allow the input bits to generate different output bits. These functions are used in different levels of hash tables that are coded in Java Programming Language and a quite number of data records serve as ...

Verification of Implementations of Cryptographic Hash Functions
IEEE Access, 2017 Cryptographic hash functions have become the basis of modern network computing for identity authorization and secure computing; protocol consistency of cryptographic hash functions is one of the most important properties that affect the security and ...

The Grindahl Hash Functions [PDF]
, 2007 In this paper we propose the Grindahl hash functions, which are based on components of the Rijndael algorithm. To make collision search sufficiently difficult, this design has the important feature that no low-weight characteristics form collisions, and at the same time it limits access to the state.

Universal Classes of Hash Functions
Journal of Computer and System Sciences, 1979 AbstractThis paper gives an input independent average linear time algorithm for storage and retrieval on keys. The algorithm makes a random choice of hash function from a suitable class of hash functions. Given any sequence of inputs the expected time (averaging over all functions in the class) to store and retrieve elements is linear in the length of ...
