Application of some number theory fundamentals in signal processing
Čížek, Václav ; Švandová, Hana
The paper presents basic concepts of the number theory and some properties of operations with integers that find applications in the digital signal processing. Hereien come the Euclid's algorithm and its use for evaluating continued fractions, solution of congruence equations and of diophantine equantions, multiplicative inverse and the Chinese remainder theorem.
Simulation of the enciphering algorithm RSA in MATLAB
Čížek, Václav ; Švandová, Hana
Enciphering algorithm RSA is up to now hold for one almost not decipherable methods of enciphering. At present it is used also for the electronic signature. The algorithm is based on elementary knowledge in number theory like congruence, Euler function and modular inversion. Because some number theoretic operations mey be processed in MATLAB it is shown, how the RSA algorithm can be simulated in MATLAB. Results and some simulation difficulties of the RSA algorithm are presented.
