Explores the foundational notion of secure communication by analyzing how cryptosystems are built on top of computational hardness assumptions. Covers cryptographic one-way functions, trap-door functions, pseudorandom generators, public/private-key encryption schemes, computational indistinguishability, digital signatures, message authentication, and zero-knowledge/interactive proof systems. Applications to e-commerce and e-trade.
