Abstract
This course introduces basic concepts in cryptography and computer security and discusses both their theoretical foundations and practical applications. Various threats, attacks and countermeasures including cryptosystems, cryptographic protocols and secure systems/networks will be addressed.

The course will cover: brief history of cryptography, encryption (conventional and public key), digital signatures, hash functions, message authentication codes, randomness, unconditional and computational security, zero-knowledge protocols, secure e-commerce, group communication security, anonymity, key escrow. A few popular security mechanisms (e.g., Secure IP, SSL, PGP) will also be discussed.
