Spatiotemporal chaotic one-way Hash function construction based on coupled tent maps
Tongxin xuebao, 2007 A novel coupled tent maps-based spatiotemporal chaotic cryptographic Hash function was proposed.Compared with the discrete tent map,the coupled discrete tent spatiotemporal chaotic maps have longer computer-realization-period,nearly uniform distribution ...

Cuckoo Hashing in Cryptography: Optimal Parameters, Robustness and Applications [PDF]
arXiv, 2023 Cuckoo hashing is a powerful primitive that enables storing items using small space with efficient querying. At a high level, cuckoo hashing maps $n$ items into $b$ entries storing at most $\ell$ items such that each item is placed into one of $k$ randomly chosen entries. Additionally, there is an overflow stash that can store at most $s$ items.

Random Bit Generator Mechanism Based on Elliptic Curves and Secure Hash Function [PDF]
arXiv, 2020 Pseudorandom bit generators (PRBG) can be designed to take the advantage of some hard number theoretic problems such as the discrete logarithm problem (DLP). Such type of generators will have good randomness and unpredictability properties as it is so difficult to find an easy solution to the regarding mathematical dilemma.

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 ...

On the (Im)plausibility of Public-Key Quantum Money from Collision-Resistant Hash Functions [PDF]
arXiv, 2023 Public-key quantum money is a cryptographic proposal for using highly entangled quantum states as currency that is publicly verifiable yet resistant to counterfeiting due to the laws of physics. Despite significant interest, constructing provably-secure public-key quantum money schemes based on standard cryptographic assumptions has remained an elusive

Asymmetric cryptography and practical security
Journal of Telecommunications and Information Technology, 2002 Since the appearance of public-key cryptography in Diffie-Hellman seminal paper, many schemes have been proposed, but many have been broken. Indeed, for many people, the simple fact that a cryptographic algorithm withstands cryptanalytic attacks for ...
