Commitment Scheme and PRNG

This lecture covers the commitment scheme, key derivation function, and pseudorandom generator. It explains how commitment to play Rock-Paper-Scissors ensures fairness and integrity in cryptographic protocols. The instructor discusses the importance of commitment schemes in various applications, such as coin tossing and cryptographic key generation. Additionally, the lecture delves into the security aspects of cryptographic primitives like pseudorandom functions and their role in ensuring data integrity and authentication. Various examples and failure cases are explored to illustrate the significance of robust cryptographic mechanisms.
