Secure Multiparty Computation: Oblivious Transfer

This lecture covers the concept of secure multiparty computation (SMC) focusing on the protocol of Oblivious Transfer. It explains how SMC allows multiple parties to jointly compute a function while keeping their inputs private. The lecture details the requirements, functionalities, and realizations of Oblivious Transfer, emphasizing its applications in SMC. It also delves into the security aspects of Oblivious Transfer protocols, such as privacy guarantees for both senders and receivers. Additionally, the lecture introduces Garbled Circuits as a method to securely evaluate complex functions in SMC, highlighting the implementation and limitations of this approach.
