Applications of linear algebra in encryption

Tóm tắt

Information security is always a crucial issue in the continuously developing society. There are many solutions that have been proposed to secure information. In this article, the author discusses the introduction of encryption using knowledge from the Linear Algebra course to first-year students so that they can perceive the application of Linear Algebra. The information encryption process uses the knowledge of matrices, matrix operations, inverse matrices, transposition, Gauss elimination, linear transformation
