Are there properties of networks that affect the spread of anti-virus countermeasures? Is countermeasure spreading more effective through one network than through another? In this paper, we investigate this problem by simulating the impact of network topology on the effectiveness of anti-virus countermeasures. We simulate the spread of countermeasures based on the idea that computer viruses and...

A growing number of connected objects, with their high performance and low-resources constraints, are embedding lightweight ciphers for protecting the confidentiality of the data they manipulate or store. Since those objects are easily accessible, they are prone to a whole range of physical attacks, one of which are fault attacks against for which countermeasures are usually expensive to implem...

The algorithm proposed by Ha and Moon [2] is a countermeasure against power analysis. The Ha-Moon algorithm has two drawbacks in that it requires an inversion and has a right-to-left approach. Recently, Yen, Chen, Moon and Ha improved the algorithm by removing these drawbacks [7]. Their new algorithm is inversion-free, has a left-toright approach and employs a window method. They insisted that ...

Despite efforts by the U.S. an its allies to debilitate the al-Qaeda organization in the eight years since the September 11 th terrorist attacks, al-Qaeda continues to operate and poses a national security threat to the U.S. Recent research indicates that part of alQaeda’s success hinges upon the organization’s ability to function in a decentralized manner. This paper analyzes alQaeda using the...

At present, the employment situation of college graduates is grim, which has caused wide concerns in the whole society. How to improve the competitiveness of college graduates, to adapt to the employment environment, to help college graduates to smooth employment has become an urgent problem to be solved. According to the investigation of college graduates’ employment environment, the author an...

Driver sleepiness is a major contributor to severe crashes and fatalities on our roads. Many people continue to drive despite being aware of feeling tired. Prevention relies heavily on education campaigns as it is difficult to police driver sleepiness. The video sharing social media site YouTube is extremely popular, particularly with at risk driver demographics. Content and popularity of uploa...

Physical model tests with the scale of 1:36 are carried out in the Near-Shore Wave Basin (NSWB) at Tainan Hydraulics Laboratory (THL) with the jacket-type offshore wind turbine foundation (jacket-type foundation) and the combination of hard or soft scour protection in the test area. Scouring around the jacket-type foundation exposed to wave and current was conducted in the NSWB with a mobile be...

In the crypto community, it is widely acknowledged that any cryptographic scheme that is built with no countermeasure against sidechannel analysis (SCA) can be easily broken. In this paper, we challenge this intuition. We investigate a novel approach in the design of cryptographic primitives that promotes inherent security against side-channel analysis without using redundant circuits. We propo...

Orthostatic intolerance follows actual weightlessness and weightlessness simulated by bed rest. Orthostasis immediately after acute exercise imposes greater cardiovascular stress than orthostasis without prior exercise. We hypothesized that 5 min/day of simulated orthostasis [supine lower body negative pressure (LBNP)] immediately following LBNP exercise maintains orthostatic tolerance during b...

We previously tested the P300-based Complex Trial protocol for deception detection against 2 and 4 countered of 4 irrelevant stimuli. The protocol detected 90-100% of these subjects with <10% false positives. We have also shown that Reaction Time (RT) to the first trial stimulus is increased (group effect) with countermeasure use. We also reported a new P900 component associated with countermea...
