ab: Summary: This article describes Cryptography, defined as the science of
encrypting and deciphering messages written in secret codes, it has
played a vital role in securing information since ancient times. There
are several cryptographic techniques and many make extensive use of
mathematics to secure information. The author discusses an activity
built around one of the techniques that illustrates an application of
matrices. Secondary school teachers may use this activity to
consolidate their studentsâ€™ learning of certain concepts of matrices
such as the algorithm for matrix multiplication and the concept of the
multiplicative inverse of a matrix. It is hoped that this activity, not
only offers teachers great opportunities to either introduce or
consolidate certain mathematical concepts and algorithms, but also to
convince their students that mathematics plays an important role in
various walks of life and hence is a useful and meaningful field of
study. (Contains 1 table.) (ERIC)
