Ensino de matrizes aplicado a criptografia com uso de ferramentas digitais

Abstract

The aim of this work is to arouse the interest of students, giving meaning to the study of matrices, using the theory and practice, as well as appreciation of solving problems logic. The use of cryptography concepts that addresses its importance since the beginning, shows that mathematic is crucial for various segments of society. More specifically, the use of matrix applied to the encryption is a strategy that facilitates content of approach, making the most significant study. An easy approach also requires practicality and appreciation of the logical reasoning of the student. The study requires a matrices practice of calculations, which often makes the comprehensive contents, causing mental stress and does not bring meaning to the practice. In this search the appreciation of the resolution logic, we propose the use of winmat software that enables calculations make operating this content, facilitating matrix approach applied cryptography.
