Description: (3 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.

Objectives: Discover how Alice may send a secret message to Bob that nobody else can understand, how he may be certain that this message came from Alice, how she can prove him who she is with revealing anyhting about the proof (!) , and how they can exchange a secret key using dim pulses of laser light, etc.

Mandatory textbook: Cryptography - Theory and Practice (second edition) by Doug Stinson. Chapman and Hall/CRC Press, Inc. ISBN 1-58488-206-9

Evaluation: There will be 5 homework assigments worth 50% of your final grade and a final exam worth 50%. The homeworks will have some theoretical components worth 30% and applications using Maple worth 20%.
