Diffie-Hellman and El Gamal Cryptosystems

This lecture covers the Diffie-Hellman key exchange protocol, the concept of trapdoor one-way functions, and El Gamal's cryptosystem. It explains how these systems work, the importance of large prime factors, and the difficulty of breaking Diffie-Hellman. The lecture also delves into the idea of one-way functions and the significance of trapdoor functions in cryptography.
