Análise sobre a segurança do algoritmo de criptografia posicional

Abstract

In this project the security of the ―algoritmo de criptografia posicional‖ was analyzed under the attack of cryptography by the method of analysis of frequency of symbols. For this it verified if the influence of the operation mathematical mod in the construc-tion of the code keys. Then, a software was developed in C++ capable to extract the frequency of the characters of a language, of cryptography the data of a text through the method posicional‖, of obtaining the break of the cryptography for the method of analysis of frequency of symbols. It was also analyzed the importance of the degree of the cryptography function so that the cryptography keys are found.
