Data encryption is an important security measure for sensitive data stored on computers. Pupils learn how to utilize matrices for creating code. They also get a great review of matrix multiplication, inverse matrices, and the identity...

Students brainstorm and discuss the concept of cryptography, the science of secrets in today's world and then focus on a system for sending secret messages used by Julius Caesar. They make a Caesar wheel assessing encrypting and...

Students secure information online using cryptography. For this algebra lesson, students use RSA technology to encrypt information on the internet. They use modular reduction of natural numbers to understand prime number theory.

Students explore the history of cryptography. They assess function notation and transformation, matrix operations, and the fundamentals of modular arithmetic. Using graphing calculators, students develop their own encryption schemes.

Banks are responsible for keeping our financial information safe. Mathematics is what allows them to do just that! Pupils learn the math behind the cryptography that banks rely on. Using polynomial identities, learners reproduce the...

A thorough discussion of the business and professional uses of encryption.

This is the text and video of Arthur W. Coviello's keynote speech at the RSA Conference delivered on February 25, 2014, in San Francisco, California.

This site from the Global Internet Liberty Campaign reports on a 1998 survey conducted by the Electronic Privacy Information Center which asked world nations about their encryption policies. The survey got results from over 75 nations,...
