Fault Attacks on RSA with CRT: Concrete Results and Practical Countermeasures
This article describes concrete results and practically validated countermeasures concerning differential fault attacks on RSA using the CRT. We investigate smartcards with an RSA coprocessor where any hardware countermeasures to defeat fault attacks have been switched off. This scenario was chosen in order to analyze the reliability of software countermeasures. We start by describing our labor...
متن کاملPhase Sensitive Detection and Classification of Defects in Concrete Structures by Ultrasonic and Electromagnetic Imaging Techniques
Many applications of imaging techniques like diffraction tomography demonstrate their ability to image the interior of huge structures like bridges. One problem of testing concrete bridges are grouting defects in tendon ducts which may lead to corrosion of tendons yielding a degradation of the stability of the whole structure. Ultrasound is able to penetrate the tendon ducts and therefore it ma...

پژوهش حاضر در چارچوب مکتب دستکاری قرار گرفت و با استفاده از تقسیم بندی دوکات (2007) از شیوه های دستکاری، به دنبال یافتن پاسخ برای پرسش های زیر بود: 1-رایج ترین شیوه دستکاری در دوبله فیلم ها کدام است؟ 2-رایج ترین شیوه دستکاری در زیرنویس فیلم ها کدام است؟ 3-دستکاری در دوبله فیلم ها رایج تر است یا در زیرنویس آن ها؟ این پژوهش از نوع تحقیقات توصیفی- مقایسه ای و پیکره ای می باشد. پیکره تحقیق شا...
Review of Active IR Thermography for Detection and Characterization of Defects in Reinforced Concrete
Active thermography methods enable structural investigations of reinforced concrete elements taking into account many different testing problems. The goal of this review is to provide an overview on the state-of-the-art regarding the use of active infrared thermography (IRT) for detection and characterization of defects in reinforced concrete. The paper will provide the physical background, equ...
