Quantum Lightning Never Strikes the Same State Twice [PDF]

, 2017
Public key quantum money can be seen as a version of the quantum no-cloning theorem that holds even when the quantum states can be verified by the adversary.

Two-permutation-based hashing with binary mixing

Journal of Mathematical Cryptology, 2015
We consider the generic design of compression functions based on two n-bit permutations and XOR-based mixing functions. It is known that any such function mapping n+α${n+\alpha }$ to α bits, with 1≤α≤n${1\le \alpha \le n}$, can achieve at most min{2α/2 ...

Dynamic Performance and Crashworthiness Assessment of Honeycomb Reinforced Tubular Pipe in the Jacket Platform under Ship Collision

Journal of Marine Science and Engineering, 2022
The collision between the pipe legs of jacket platforms and bypassing ships is of great concern for the safety assessment of platforms. Honeycomb structures have been widely used owing to their unique deformation and mechanical properties under dynamic ...

Algebraic Collision Attacks on Keccak

IACR Transactions on Symmetric Cryptology, 2021
In this paper, we analyze the collision resistance of the two smallest versions of Keccak which have a width of 200 and 400 bits respectively. We show that algebraic and linearization techniques can serve collision cryptanalysis by using some interesting

Rotamak confinement-power-current relationships and r.f. loading resistance [PDF]

, 1989
The relationships between input power, driven current, energy confinement, temperature and density are examined in detail for existing rotamak experiments. Additionally, the loading resistance presented to the r.f.

Collision-resistant hash function based on composition of functions [PDF]

Revue Africaine de Recherche en Informatique et Mathématiques Appliquées, 2011
A cryptographic hash function is a deterministic procedure that compresses an arbitrary block of numerical data and returns a fixed-size bit string. There exists many hash functions: MD5, HAVAL, SHA, ... It was reported that these hash functions are no longer secure. Our work is focused on the construction of a new hash function based on composition of
