Description: (4 credits, 3 hours). This course presents an in-depth study of modern cryptography and data security. We investigate four important subjects of cryptography: data encryption, message authentication, user identification and key distribution. The basic information theoretic and computational security of classical and modern cryptographic systems are analysed. The course is self-contained and all necessary mathematical background will be explicitely covered.

Mandatory textbook:
Introduction to Modern Cryptography 2nd Edition , by Jonathan Katz and Yehuda Lindell.  
Publisher:
Chapman and Hall/CRC Press, Nov 2014.

Errata


Mandatory use of MAPLE :

Available labs with maple 16 installed : lab2-X, open-X, lab6-X, lab7-X, lab9-X, where X is from 1 to approximately 25.
Any student taking a cs course either has or can create a CS account.
