Optimal Collision Side-Channel Attacks [PDF]

open access: yes, 2020
Collision side-channel attacks are effective attacks against cryptographic implementations, however, optimality and efficiency of collision side-channel attacks is an open question. In this paper, we show that collision side-channel attacks can be derived using maximum likelihood principle when the distribution of the values of the leakage function is ...

Preimage and Collision Attacks on MD2 [PDF]

open access: yes, 2005
This paper contains several attacks on the hash function MD2 which has a hash code size of 128 bits. At Asiacrypt 2004 Muller presents the first known preimage attack on MD2. The time complexity of the attack is about 2104 and the preimages consist always of 128 blocks.

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 ...

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.

A Collision-Attack on AES [PDF]

open access: yes, 2004
Recently a new class of collision attacks which was originally suggested by Hans Dobbertin has been introduced. These attacks use side channel analysis to detect internal collisions and are generally not restricted to a particular cryptographic algorithm. As an example, a collision attack against DES was proposed which combines internal collisions with

Correlation-Enhanced Power Analysis Collision Attack [PDF]

open access: yes, 2010
Side-channel based collision attacks are a mostly disregarded alternative to DPA for analyzing unprotected implementations. The advent of strong countermeasures, such as masking, has made further research in collision attacks seemingly in vain.

Collision Attack on Boole

open access: yes, 2009
Boole is a hash function designed by Gregory Rose and was submitted to the NIST Hash competition. It is a stream cipher based hash function which produces digests up to 512 bits. Different variants exist, namely Boole16, Boole32 and Boole64 where the number refers to word size in bits. Boole64 is considered as the official submission.

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 ...

Two Improved Multiple‐Differential Collision Attacks [PDF]

open access: yesMathematical Problems in Engineering, 2014
In CHES 2008, Bogdanov proposed multiple‐differential collision attacks which could be applied to the power analysis attacks on practical cryptographic systems. However, due to the effect of countermeasures on FPGA, there are some difficulties during the collision detection, such as local high noise and the lack of sampling points.

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 ...
