Quality Analysis of a Chaotic Proven Keyed Hash Function [PDF]

International Journal On Advances in Internet Technology. 5(1), pp.26-33, 2012, 2016
Hash functions are cryptographic tools, which are notably involved in integrity checking and password storage. They are of primary importance to improve the security of exchanges through the Internet. However, as security flaws have been recently identified in the current standard in this domain, new ways to hash digital data must be investigated.

Using fuzzy bits and neural networks to partially invert few rounds of some cryptographic hash functions [PDF]

arXiv, 2019
We consider fuzzy, or continuous, bits, which take values in [0;1] and (-1;1] instead of {0;1}, and operations on them (NOT, XOR etc.) and on their sequences (ADD), to obtain the generalization of cryptographic hash functions, CHFs, for the messages consisting of fuzzy bits, so that CHFs become smooth and non-constant functions of each bit of the ...

Novel key management and authentication scheme for ad hoc space networks

Tongxin xuebao, 2006
To be implemented using a flexible distributed architecture consisting of a constellation of dynamically de-ployed or configured satellites that were networked together into an integrated information system,the satellites could form an ad hoc self ...

Solving Degree Bounds for Iterated Polynomial Systems

IACR Transactions on Symmetric Cryptology
For Arithmetization-Oriented ciphers and hash functions Gröbner basis attacks are generally considered as the most competitive attack vector. Unfortunately, the complexity of Gröbner basis algorithms is only understood for special cases, and it is ...

A Quantum-Resistant Photonic Hash Function [PDF]

arXiv
We propose a quantum hash function based on Gaussian boson sampling on a photonic quantum computer, aiming to provide quantum-resistant security. Extensive simulations demonstrate that this hash function exhibits strong properties of preimage, second preimage, and collision resistance, which are essential for cryptographic applications.

Performance Evaluation of Hashing Algorithms on Commodity Hardware [PDF]

arXiv
Hashing functions, which are created to provide brief and erratic digests for the message entered, are the primary cryptographic primitives used in blockchain networks. Hashing is employed in blockchain networks to create linked block lists, which offer safe and secure distributed repository storage for critical information. Due to the unique nature of

Lightweight PUF-based anonymous authentication protocol in V2G

Tongxin xuebao
To address the issues of incomplete functionality, high communication overhead, and high computational cost in existing vehicle-to-grid (V2G) network authentication protocols, a lightweight anonymous authentication protocol based on physical unclonable ...
