Teoria dos Números e criptografia com aplicações básicas

Abstract

This work is a guiding approach consists of examples of practical applications and presentation of important concepts related to number theory, confronting the current way of inserting these in basic education which often are considered boring and devoid of practicality. For this reason, it has been Cryptography as a science of great practical applicability of these, especially nowadays due to the flow of important transactions by electronic means, subject to interception by third parties. On occasion some subjective methods of cryptography, with emphasis on the RSA method, a major public-key cryptosystem was presented. Thus, from the earliest historical accounts the chapters theoretical foundation was always possible to realize the importance of these issues, in particular the cryptographic processes studied, a significant contribution to the teaching that demystifies and provides a constructivist learning, as we believe that students can make great discoveries as creating subject of his ideas, especially in problem solving.
