OBJECTIVE Integration of patients' records across resources enhances analytics. To address privacy concerns, emerging strategies such as Bloom filter encodings (BFEs), enable integration while obscuring identifiers. However, recent investigations demonstrate BFEs are, in theory, vulnerable to cryptanalysis when encoded identifiers are randomly selected from a public resource. This study investi...

On smart-cards, Elliptic Curve Cryptosystems (ECC) can be vulnerable to Side Channel Attacks such as the Re ned Power Analysis (RPA). This attack takes advantage of the apparition of special points of the form (0, y). In this paper, we propose a new countermeasure based on co-Z formulæ and an extension of the curve isomorphism countermeasure. It permits to transform the base point P = (x, y) in...

How can virus countermeasures such as software patches or warnings be disseminated and installed more efficiently than they are currently so that fewer organizations will suffer virus infection problems? The relative effectiveness of four anti-virus strategies is examined formally using simulations. One of these strategies is the countermeasure spreading strategy (CMS). CMS is based on the idea...

This letter introduces the concept of antifragile electronic warfare (EW), which we define as the ability to allow a communications link to improve performance due to the presence of a jammer. This concept should not be confused with jamming countermeasures (a.k.a. anti-jamming or electronic protection). Rather, antifragile EW can be thought of as the next step beyond simply avoiding or mitigat...

The "Variable Vector Countermeasure Suit (V2Suit) for Space Habitation and Exploration" is a novel system concept that provides a platform for integrating sensors and actuators with daily astronaut intravehicular activities to improve health and performance, while reducing the mass and volume of the physiologic adaptation countermeasure systems, as well as the required exercise time during long...

We found countermeasures to protocols using P300 in concealed information tests. One, the "six-probe" protocol, in Experiment 1, uses six different crime details in one run. The countermeasure: generate covert responses to irrelevant stimuli for each probe category. Hit rates were 82% in the guilty group; 18% in the countermeasure group. The average reaction time (RT) distinguished these two gr...

Implementation security for lattice-based cryptography is still a vastly unexplored field. At CHES 2016, the very first side-channel attack on a lattice-based signature scheme was presented. Later, shuffling was proposed as an inexpensive means to protect the Gaussian sampling component against such attacks. However, the concrete effectiveness of this countermeasure has never been evaluated. We...

OBJECTIVES The current study aimed to examine the effectiveness of a resistive vibration exercise countermeasure during prolonged bed-rest in preventing lower-limb muscle atrophy. METHODS 20 male subjects underwent 56-days of bed-rest and were assigned to either an inactive control, or a countermeasure group which performed high-load resistive exercises (including squats, heel raises and toe ...

We propose and analyse a new countermeasure against Differential Power Analysis (DPA) for the AES encryption algorithm, based on permutation tables. As opposed to existing AES countermeasures, it does not use random masking. We prove that our new countermeasure is resistant against first-order DPA; we also show that it is quite efficient in practice.

In this report, we investigate the possibility of production of a novel new anthrax treatment with minimal side effects and virtually no possibility of bacterial resistance. The pharmaceutical is based on the innovative combination of two recently discovered components: an agent that aids the immune system in defeating an anthrax infection and the “bait” by which to attack the anthrax in vivo. ...
