Abstract: This article presents the results of a bibliographic research on cryptography, focusing on the Hill Cipher and its use as a playful tool in the teaching of matrices. Encryption, widely used in data and information protection today, as well as any other invention of man, has undergone several changes over time. From the substitution ciphers, used mainly by Emperor Julius Caesar, to quantum cryptography, especially used by intelligence services, numerous ciphers have been created and used over the centuries. Some easily breakable, others extremely secure – merit of mathematics – all the ciphers already created reveal the fascinating world of cryptography, rich historically and mathematically. Hill's cipher proves to be a good tool for addressing the content of matrices in high school, using it as a playful tool, and different from the traditional association made with tables. In this work will be exposed some results of modular aritmetic and algebra, in particular, results such as congruences, equivalence relationships equivalence classes and matrix operations in . This exhibition aims to support the functioning of the cryptographic method known as Hill Cipher, the object of study of this article.
