In the last part in this work, we are proposing three activities to be applied in classroom. / Neste trabalho, vamos estudar a evolução da criptografia ao longo da história; analisar a diferença entre as criptografias simétricas e assimétricas; enunciar definições e teoremas sobre relações binárias, teoria dos grupos, raízes primitivas e logaritmos discretos; entender o procedimento do protocolo da troca de chaves de Diffie-Hellman; e, na parte final deste trabalho, iremos propor três atividades para serem aplicadas em sala de aula.
