CRIPTOGRAFIA NO ENSINO BÁSICO

Abstract

A criptografia, a cada dia que se passa, tem ficado mais em evidência na nossa sociedade. Muitas atividades humanas necessitam da transmissão segura e sigilosa de dados. Grande parte das pessoas desconhecem que, ao realizarem transações bancárias online, ou ao trocarem mensagens por meio de aplicativos em smartphone, utilizam pelo menos um método de criptografia como recurso de segurança. Alguns modelos criptográficos têm interseção com conteúdos matemáticos trabalhados na educação básica. Nesse sentido, o estudo da criptografia tem se mostrado como uma estratégia promissora, uma vez que trabalha com modelagem de conteúdos matemáticos, aliados a uma base teórica desses conteúdos. Neste artigo, apresentaremos a Criptografia de César e a Criptografia RSA. Com o objetivo de facilitar o processo de aprendizagem, trabalhamos com os programas Google Planilhas e Wolfram Alpha no processamento dos cálculos. Esses recursos foram utilizados com o objetivo de consolidar os conteúdos vistos em sala de aula. Para além, o trabalho com o Google Planilhas pode, mesmo que de maneira rudimentar, ser um primeiro contato do aluno com uma linguagem de programação. Este artigo é uma síntese de parte da dissertação do primeiro autor. Este trabalho foi apresentado no II Workshop Online Nacional do Profmat e II Encontro Mineiro do Profmat.
