Anonymous Communications: Toolbox for Privacy Engineering

This lecture covers the toolbox for privacy engineering, focusing on anonymous communications. It introduces the course aim, notions to express privacy in communications, mechanisms to protect traffic data, and attacks to consider when protecting traffic data. The lecture delves into the importance of understanding the need for privacy, key infrastructure decisions, and protection goals. It discusses the encoding of metadata information, the challenges with encryption, and the abstract model of anonymous communications. Various techniques like pseudoidentifiers and location encoding are explored, along with the concept of traffic analysis and the need for protecting communication layers.
