Math 481 syllabus
Course Description: This course provides an introduction to classical and modern methods of message
encryption and decryption (cryptography) as well as possible attacks to cryptosystems
(cryptanalysis). Topics include classical (symmetric) cryptosystems (DES, AES), public-key
(asymmetric) cryptosystems (Diffie-Hellman, RSA, ElGamal), modes of operation, one-way
and trapdoor functions, Hash functions, cryptographic protocols. Credit for both MA
481 and MA 581 is not allowed.
Prerequisites: C or better in MA 311
Suggested Text: Wade Trappe and Lawrence C. Washington: Introduction to Cryptography with Coding Theory, 2nd edition, Pearson Prentice Hall, Upper Saddle River, NJ, 2006
Learning outcomes: Upon the successful completion of the course a student will:
Know several techniques for message encryption and decryption as well as possible
attacks to cryptosystems.
Know how mathematics can be used to protect data and make electronic systems secure.
Understand the importance of pure mathematics, especially number theory and algebra, in our current world.
