Description

This lecture covers the concept of semantic security in stream ciphers, focusing on pseudorandom number generators, expansion, and pseudorandomness conditions. It also discusses the implementation of stream ciphers with secret keys and the computational limitations faced by cryptanalysts. The instructor presents examples related to integer factorization and computational security assumptions, emphasizing the importance of intractability assumptions in cryptography.
