Public Key Distribution Schemes | IS - 8.2

In this video, we examine the 4 General Schemes for Public Key Distribution. We start with the simple methods: Public Announcement (vulnerable to forgery) and Publicly Available Directory (trusted but centralized). We then dive deep into the advanced methods. We explain the Public-Key Authority, detailing the complete 7-step handshake where A and B request signed keys and perform mutual authentication using nonces (N1, N2). Finally, we cover the modern standard: Public-Key Certificates. We explain the Registration Phase (getting signed CA/CB from the Authority) and the Exchange Phase, showing how users swap certificates directly to avoid the bottleneck of a central server.
