Resumo
This paper makes a brief reading on the crisis experienced by the mathematics education
in Brazilian public schools in recent years, analyzing some of the reasons and
motives of this crisis and trying to point out ways that this teaching will become better,
more e cient and above all presenting mathematics as a fundamental importance
for today's world science, pointing their applicability in everyday situations that may
arouse the interest of students and present themselves as challenges to their ability to
think and learn. In order to show the applicability and the importance of mathematics
shows the encryption, if elected as a basis for analysis the cryptographic method RSA,
one of the most widespread throughout the world, to present it as a tool that uses
mathematical algorithms to encoding and/or decoding of data, enabling the protection
and con dentiality of sensitive information transmitted via satellite in commercial
and banking transactions. The paper presents the general importance of cryptography
in the context of a globalized and technological world of today, as well as within the
story, noting even its decisive contribution to the Allied victory against the Germans
in the 2nd World War. It presents also the mathematical basis for encryption, prior
knowledge of mathematics that are used to encrypt messages and or data, and presents
examples of encoding and decoding simple messages. Finally, a general approach on
the encryption is done, since its concept and common de nitions, pointing secured requirements
for its use and the main types of algorithms for encryption and decryption
codes, also called cryptographic keys.
