Among all countermeasures that have been proposed to thwart side-channel attacks against RSA implementations, the exponent randomization method – also known as exponent blinding – has been very early suggested by P. Kocher in 1996, and formalized by J.-S. Coron at CHES 1999. Although it has been used for a long time, some authors pointed out the fact that it does not intrinsically remove all so...

This paper provides a novel health monitoring classification algorithm to estimate the level of valve leakage in reciprocating compressors. It is expected that will change shape pressure-volume diagram. method constructs feature space using polytropic exponent during expansion and compression phases as well discharge suction loss power. These features are extracted by measuring in-cylinder pres...

In England in 1930, using a strain of Aujeszky virus, 1 I was unable by intracerebral or intramuscular inoculation to secure infection of a rhesus monkey. Remlinger and Bailly (1933) also recorded failure with another species--Inuus ecaudatus. With the Iowa strain of pseudorabies virus, and with an Hungarian strain, ~ intracerebral injection at Princeton (1932) was successful in each of 5 cases...

In this paper we propose a new side channel attack, where exponent recodings for public key cryptosystems such as RSA and ECDSA are considered. The known side channel attacks and countermeasures for public key cryptosystems were against the main stage (square and multiply stage) of the modular exponentiation (or the point multiplication on an elliptic curve). We have many algorithms which achie...

Currently, acoustic methods are widely used as a way to detect pipeline leaks. This is due the fact that signal has sufficiently capacious information about state of pipeline. The effectiveness monitoring depends on correct extraction this from diagnostic signal. there search for new, more effective analyzing signals. article proposes apply theory fractals determine One most accurate determinin...

abstract. in this paper we study some relations between the power andquotient power graph of a finite group. these interesting relations motivateus to find some graph theoretical properties of the quotient power graphand the proper quotient power graph of a finite group g. in addition, weclassify those groups whose quotient (proper quotient) power graphs areisomorphic to trees or paths.

we prove that for $p>7$ there are‎ ‎[‎ ‎p^{4}+2p^{3}+20p^{2}+147p+(3p+29)gcd (p-1,3)+5gcd (p-1,4)+1246‎ ‎] ‎groups of order $p^{8}$ with exponent $p$‎. ‎if $p$ is a group of order $p^{8}$‎ ‎and exponent $p$‎, ‎and if $p$ has class $c>1$ then $p$ is a descendant of $‎p/gamma _{c}(p)$‎. ‎for each group of exponent $p$ with order less than $‎p^{8} $ we calculate the number of descendants of o...

The non-abelian tensor product of groups which has its origins in algebraic K-theory as well as inhomotopy theory, was introduced by Brown and Loday in 1987. Group theoretical aspects of non-abelian tensor products have been studied extensively. In particular, some studies focused on the relationship between the exponent of a group and exponent of its tensor square. On the other hand, com...

Indentation is a new method for estimating residual stress. The plastic behavior of the materials under study can affect indentation parameters and, thus, influences the results of residual stress measurement. In this paper, the effect of yield stress and work-hardening exponent on the accuracy of residual stress measurements in steels and aluminums was studied. Results showed that, for m...
