Automatic collision avoidance of ships [PDF]

open access: yes, 2008
One of the key elements in automatic simulation of ship manoeuvring in confined waterways is route finding and collision avoidance. This paper presents a new practical method of automatic trajectory planning and collision avoidance based on an artificial

Surface damage evolution of artillery barrel under high-temperature erosion and high-speed impact

open access: yesCase Studies in Thermal Engineering, 2023
Thermochemical erosion and mechanical wear are the primary sources of surface damage in artillery barrel chambers, severely restricting the interior ballistic characteristics and service life of the barrel weapon.

Detection of attack behaviour of pig based on deep learning

open access: yesSystems Science & Control Engineering, 2023
Attack behaviour detection of the pig is a valid method to protect the health of pig. Due to the farm conditions and the illumination changes of the piggery, the images of the pig in the videos are often being overlapped, which lead to difficulties in ...

Algebraic Collision Attacks on Keccak

open access: yesIACR 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

Single-block collision attack on MD5 [PDF]

open access: yes, 2012
In 2010, Tao Xie and Dengguo Feng \cite{cryptoeprint:2010:643} constructed the first single-block collision for MD5 consisting of two 64-byte messages that have the same MD5 hash.

Internal collision attack on Maraca [PDF]

open access: yes, 2009
We present an internal collision attack against the new hash function Maraca which has been submitted to the SHA-3 competition. This attack requires 2^{237} calls to the round function and its complexity is lower than the complexity of the generic ...

Improved preimage and pseudo-collision attacks on SM3 hash function

open access: yesTongxin xuebao, 2018
A preimage attack on 32-step SM3 hash function and a pseudo-collision attack on 33-step SM3 hash function respectively were shown.32-step preimage attack was based on the differential meet-in-the-middle and biclique technique,while the previously known ...

Hypothesis Testing Based Side-Channel Collision Analysis

open access: yesIEEE Access, 2019
Side-channel collision analysis has become a research hotspot since its first publication in 2003. Compared with differential power analysis (DPA) and correlation power analysis (CPA), collision analysis does not need to know the intermediate value and ...

Differential fault analysis on EMV application cryptogram

open access: yes网络与信息安全学报, 2016
The process of application cryptogram in EMV was researched and dummy bits in session key were found.Based on the session key’s dummy bits and compressive property of DES’s Sbox,much information of the application cryptogram master key was got by using ...
