Course Description

Introducing the main concepts used in the modern cryptography is the main aim of the course. Mathematical concepts necessary for the modern crypt-algorithms are in the scope of the course. Classical encryption techniques are studied in the first chapters. Block ciphers and Date Encryption Standard (DES) is one of the main objectives of the course. Also, Advanced Encryption Standard (AES) algorithm is studied in details. Public key cryptography and RSA algorithm theory and implementations are the last topics for encryption models. The course ends with network security concepts and IP security standards. The students are expected to improve their skills with a project that requires the implementation of a cryptography algorithm and encryption/decryption of real data through the network.
