Wounding patterns and human performance in knife attacks: optimising the protection provided by knife-resistant body armour [PDF]
, 2003 Stab attacks generate high loads,1 and to defeat them, armour needs to be of a certain thickness and stiffness.2,3 Slash attacks produce much lower loads and armour designed to defeat them can be far lighter and more flexible.Methods and subjects: Phase

Algebraic Attacks on Combiners with Memory [PDF]
, 2003 Recently, algebraic attacks were proposed to attack several cryptosystems, e.g. AES, LILI-128 and Toyocrypt. This paper extends the use of algebraic attacks to combiners with memory. A (k,l)-combiner consists of k parallel linear feedback shift registers (LFSRs), and the nonlinear filtering is done via a finite automaton with k input bits and l memory ...

Water absorption and salt attack resistance of coal ash brick made of different percentage of foam content [PDF]
, 2014 Coal ash which constitute of fly ash and bottom ash were proved to be used as main component in brick production. However, published work on the coal ash brick with addition of foam in order to produce lightweight brick is still lacking. This thesis

Fault Attacks on Combiners with Memory [PDF]
, 2006 Fault attacks are powerful cryptanalytic tools that are applicable to many types of cryptosystems. Recently, general techniques have been developed which can be used to attack many standard constructions of stream ciphers based on LFSR's. Some more elaborated methods have been invented to attack RC4. These fault attacks are not applicable in general to

All You Need Is Fault: Zero-Value Attacks on AES and a New λ-Detection M&M
Transactions on Cryptographic Hardware and Embedded Systems, 2023 Deploying cryptography on embedded systems requires security against physical attacks. At CHES 2019, M&M was proposed as a combined countermeasure applying masking against SCAs and information-theoretic MAC tags against FAs.

New, efficient and robust, fiber-based quantum key distribution schemes [PDF]
, 2002 We present a new fiber based quantum key distribution (QKD) scheme which can be regarded as a modification of an idea proposed by Inoue, Waks and Yamamoto (IWY) [1].

Combined Attacks and Countermeasures [PDF]
, 2010 Logical attacks on smart cards have been used for many years, but their attack potential is hindered by the processes used by issuers to verify the validity of code, in particular bytecode verification. More recently, the idea has emerged to combine logical attacks with a physical attack, in order to evade bytecode verification.

Imaging markers of disability in aquaporin-4 immunoglobulin G seropositive neuromyelitis optica: a graph theory study [PDF]
, 2019 Neuromyelitis optica spectrum disorders lack imaging biomarkers associated with disease course and supporting prognosis. This complex and heterogeneous set of disorders affects many regions of the central nervous system, including the spinal cord and ...
