Lecture
This lecture covers the limitations of TCP, the Transport Layer Security Handshake, and the importance of cryptographically authenticating all exchanges to prevent TCP hijacking. It also explains the goals and steps of the Transport Layer Security (TLS) protocol, including the TLS handshake process and the forward secrecy it provides. The lecture delves into the challenges and vulnerabilities of TLS, such as downgrading attacks, BEAST, Padding Oracle, Lucky Thirteen, and renegotiation attacks, highlighting the importance of provable security in TLS 1.3.
