Information leakage of general input operations using button images in graphical user interface on touch screen monitors was experimentally investigated from images reconstructed by receiving the electromagnetic noise. In the experimental investigations for input operations of a personal identification number, it was confirmed that when a button image was touched, the touched button image can b...

The effect of a combined system of the bed suction and jet injection as a pier-scour countermeasure on the turbulent flow field is studied in a laboratory flume using an Acoustic Doppler Velocimeter (ADV). The three components of the velocities in the vertical symmetry plane in the equilibrium scour hole in front and rear of the pier under 3-jet injections and bed suction rate Qs/Q0 = 2%located...

Cryptosystems are highly sensitive to physical attacks, which leads security developers to design more and more complex countermeasures. Nonetheless, no proof of flaw absence has been given for any implementation of these countermeasures. This paper aims to formally verify an implementation of one published countermeasure against fault injection attacks. More precisely, the formal verification ...

Low Entropy Masking Schemes (LEMS) are a recent countermeasure against side-channel attacks. They aim at reducing the randomness requirements of masking schemes under certain (adversarial and implementation) conditions. Previous works have put forward the interest of this approach when such conditions are met. We complement these investigations by analyzing LEMS against adversaries and implemen...

As the course of economy globalization and trade liberalization have been speeding up, the protective in the international trade have changed greatly. Especially in the recent years, it is widely recognized that technical barriers to trade create numerous obstacles to the international exchange of primary and processed products in The EU and US markets. This article proposes the definition and ...
