Horizontal collision correlation analysis (HCCA) imposes a serious threat to simple power analysis resistant elliptic curve cryptosystems involving unified algorithms, for e.g. Edward curve unified formula. This attack can be mounted even in presence of differential power analysis resistant randomization schemes. In this paper we have designed an effective countermeasure for HCCA protection, wh...

We show that a randomized addition-subtraction chains countermeasure against side channel attacks is vulnerable to SPA attack, a kind of side channel attack, under distinguishability between addition and doubling. A side channel attack is an attack that takes advantage of information leaked during execution of a cryptographic procedure. The randomized addition-subtraction chains countermeasure ...
BIODEFENSE PLANNING BY THE U.S. government emphasizes the use of medical countermeasures, including drugs and vaccines, to prepare for and respond to attacks involving biological weapons.1–4 Currently, medical countermeasures are available for only a fraction of biological threats, including those representing the highest risk, as determined by the Department of Homeland Security’s (DHS) threat...
Caffeine is regarded as a mild stimulant acting on the central nervous system that is responsible for a significant portion of the behavioural and physiological effects of coffee and tea. Motives why people take caffeine are reflected in consumption patterns. Early in the morning caffeine might help to wake up, whereas during the day it is an aid to stay awake or counteract fatigue. The intake ...
A new digital countermeasure against attacks related to the clock frequency is presented. This countermeasure, known as frequency sensor, consists of a local oscillator, a transition detector, a measurement element and an output block. The countermeasure has been designed using a full-custom technique implemented in an Application-Specific Integrated Circuit (ASIC), and the implementation has b...
Successful timing attacks against public-key cryptosystems have been demonstrated in many forms, suggesting the use of a technique known as blinding as countermeasure to these attacks. An alternative countermeasure has been considered, though somewhat overlooked and less studied in existing literature, consisting of idle-wait to make the decryption time independent of the data. In this work, we...
The authors have been developing the automatic scheduling systems for software development project, which deliver scheduling and worker assignment. Their earlier works were designed to draw on crashing and fast tracking to produce countermeasure plans against process delay. However, process delay can be recovered not only by crashing or fast tracking but also by using holiday works. Their earli...
Despite knowledge gained through decades of research, fatigue due to insuffi cient sleep remains an ingrained part of military and commercial aviation and represents a major threat to the health, safety, and effectiveness of aircrew. Long duty periods, high workloads, circadian disruptions, and insuffi cient recovery time between fl ights ensure sleepiness is a continued problem for both civili...
In this paper we propose a multiplicative blinding scheme for protecting implementations of a scalar multiplication over elliptic curves. Specifically, this blinding method applies to elliptic curves in the short Weierstraß form over large prime fields. The described countermeasure is shown to be a generalization of the use of random curve isomorphisms to prevent side-channel analysis, and our ...
