Ship resistance in random ice field of small ice floes made of the substitute material
Zhongguo Jianchuan Yanjiu, 2022 ObjectivesThis study focuses on the feasibility of a ship resistance model test in an ice field of small ice floes made of substitute material in order to reveal the resistance components and thereby provide technical support for the design of ice-going ...

On Quantum Collision Resistant Function [PDF]
Uchenye Zapiski Kazanskogo Universiteta. Seriya Fiziko-Matematicheskie Nauki, 2021 In the classical hashing theory, collision is a coincidence of the values of a function with different arguments. This paper formulates a quantum analogue of the collision property. A variant of formalization of the concept of quantum function resistant to collisions was proposed.

Electron transport in Coulomb- and tunnel-coupled one-dimensional systems [PDF]
, 2000 We develop a linear theory of electron transport for a system of two identical quantum wires in a wide range of the wire length L, unifying both the ballistic and diffusive transport regimes.

New hash function based on C-MD structure and chaotic neural network
网络与信息安全学报, 2023 In recent years, widely used hash algorithms such as MD5 and SHA-1 have been found to have varying degrees of security risks.The iterative structure of the SHA-2 algorithm is similar to that of SHA-1, making it vulnerable to attacks as well.Meanwhile ...

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 ...
