Cryptography 101: Unlocking Quantum Algorithms & Future Security 🔐

Welcome to 'Quantum Algorithms & Cryptography' course !

This lecture is an introductory session on cryptography that goes beyond the traditional concept of encryption. The lecture emphasizes that cryptography encompasses a much broader range of applications and explores some cutting-edge primitives in the field. The lecture begins by discussing secure multiparty computation. It then discusses program obfuscation, a method that protects algorithms or code by transforming them into a form that is difficult to reverse engineer while preserving the original functionality. The lecture explores the concept of deniable encryption, a technique that allows the sender of an encrypted message to plausibly deny the content of the message even if the encryption key is revealed. The lecture also covers the importance of randomness in encryption algorithms. The lecture then discusses functional encryption, an advanced form of encryption that allows computations on encrypted data without revealing the underlying data. Finally, the lecture highlights the privacy aspect of encryption schemes, emphasizing that they are not designed to provide integrity and discusses the need for different cryptographic tools for integrity.
