Design and Implementation of the Components of the Symmetric Cryptographic Algorithm
2017 IEEE Second International Conference on Data Science in Cyberspace (DSC), 2017Cryptographic technology is the basic and core technology to guarantee network and information security. It is imperative to standardize cryptographic algorithms. Cryptographic algorithm test is the most important research content of cryptographic normalization. Symmetric cryptographic algorithms are the most widely studied and applied.

On a functional equation with a symmetric component
Publicationes Mathematicae Debrecen, 2009Summary: Let \(I\subset \mathbb{R}\) be a nonvoid open interval and \(r\neq 0,1\), \(q\in(0,1)\), such that \(r\neq q\), \(r\neq \frac {1}{2}\) and \(q\neq \frac{1}{2}\). In this paper, we give all the functions \(f,g:I\to\mathbb{R}_+\) such that \[ f\left(\frac{x+y}{2}\right)\left[r(1-q)g(y)-(1-r)qg(x)\right]=\frac{r-q}{1-2q} \left[(1-q)f(x)g(y)-qf(y ...

Symmetrical-component impedance notation
Electrical Engineering, 1938No entirely adequate and consistent notation for impedances in symmetrical components has been presented in the books on symmetrical components nor has such a notation come into general use. In particular, the symbols Z 0 , Z 1 , Z 2 have been used with two entirely different meanings (as described in this letter) which cannot but lead to confusion. I

Symmetrical Component Adaptive Beamforming
The Journal of the Acoustical Society of America, 1968The theory of symmetrical components, long used in connection with fault-current analyses of multiphase power-distribution systems, has been applied to the problem of adaptive beamforming with the result that the response of a spatially diverse array of sensors can be made virtually free of the effects of the stationary part of the surrounding noise ...

Symmetrical-Components Analysis of the Four-Phase System
Transactions of the American Institute of Electrical Engineers, 1944Symmetrical-components concepts are developed for the currents, voltages, and impedances of a four-phase system, and formulas are given for various types of short circuits. The idea of symmetry among the members of each set is based on the angular displacement between the members of the set, rather than that of phase rotation which fits the three-phase
