Cryptography: General Framework

This lecture covers the basic principles of cryptography, including symmetric and asymmetric cryptography, confidentiality, integrity, and responsibility. It explains the goals of cryptography, such as combating information theft, manipulation, destruction, denial, identity theft, and bypassing defenses. The lecture also delves into encryption, decryption, and the importance of confidentiality, integrity, and responsibility in information security. Different levels of attack scenarios are discussed, along with examples of symmetric and asymmetric encryption systems like One-Time Pad, RSA, and Diffie-Hellman. The lecture emphasizes the universal need for encryption, especially in the era of cloud computing.
