CST262 — Cryptographic Systems
CST 262 - Cryptographic Systems CST 262 - Cryptographic Systems This course provides a detailed exposure to the many different cryptographic techniques and systems employed in secure transmission and storage of data. Symmetric versus asymmetric encryption and decryption, the importance of key length and algorithm complexity, and applications for encryption and hashing are presented. The characteristics of secure web transactions, including VPN tunnels, secure email, secure FTP, and secure telnet, as well as the various security protocols, are also covered. Describe the operation of DES, 3 DES, and AES cryptosystems. Explain the operation of RSA, ElGamal, and Elliptic curve cryptosystems. Understand how message integrity and authentication are performed. Be familiar with MD 5 and SHA hashing and where it is used. Send and receive secure email using PGP and S/MIME. Demonstrate the use of transport layer and network layer security.
