SCA(Side-channel analysis) is a well-known method to recover the sensitive data stored in security products. Meanwhile numerous countermeasures for hardware implementation of cryptographic algorithms are proposed to protect the internal data against this attack fortunately. However, some designs are not aware that the protection of the plaintext and ciphertext is also crucial. In this work, we ...

Solving systems of nonlinear equations is perhaps one of the most difficult problems in all numerical computation. Although numerous methods have been developed to attack this class of numerical problems, one of the simplest and oldest methods, Newton’s method is arguably the most commonly used. As is well known, the convergence and performance characteristics of Newton’s method can be highly s...

for better management of asthma it is essential that patients adjust their treatment according to the medical plan developed by the health care professionals. to achieve this goal, patients should assess the severity of their disease regularly. the purpose of this study was to determine the effect of regular measurement of peak expiratory flow and patient education on self management of asthma....

We investigate side-channel attacks where the attacker only needs the Hamming weights of several secret exponents to guess a longterm secret. Such weights can often be recovered by SPA, EMA, or simply timing attack. We apply this principle to propose a timing attack on the GPS identification scheme. We consider implementations of GPS where the running time of the exponentiation (commitment phas...

" with a guess to get out, obtain in another way (possibly from a different message) and compare to verify the guess. Past efforts to address guessing attacks in terms of design or analysis always lacked a general definition and a general analysis approach for guessing attacks. Further, they always assumed that the protocols will be implemented without type-flaws and without interaction from ot...

Analyzing network traffic activities is imperative in security to detect attack patterns. Due the complex nature of event caused by continuously changing computing environments and software applications, identifying patterns one challenging research topics. This study focuses on analyzing effectiveness integrating Multi-Resolution Analysis (MRA) visualization activities. In detail, a Discrete W...

This study investigated the utility of all of the above (AOTA) as a test option in multiple-choice items. It aimed at estimating item fit, item difficulty, item discrimination, and guess factor of such a choice. Five reading passages of the Key English Test (KET, 2010) were adapted. The test was reconstructed in 2 parallel forms: Test 1 did not include the abovementioned alternative, whereas Te...
