Censorship Systems

In this module we learn the basic components of the censorship systems, the censor model and the related challenges. We learn to define the censor's sphere of influence and sphere of visibility, and their impact on the techniques that can be deployed by the censorship systems. We will be able to describe the basic components of the censor's attack model, explain different fingerprinting methods and evaluating their strength and weakness. We will study different direct censorship method and learn the limitations imposed upon the range of censorship actions. ...

Censorship Resistance System (CRS)

In this module, we will learn the two main functional components of censorship resistance system (CRS) and explain the steps to establish the CRS communications. We will understand the operating requirements for establishing the CRS communications and learn the techniques for hiding information and avoid tracking using CRS channels. We will learn the basic CRS properties shared by CRS' and their purposes. We will comprehend different methods for obtaining CRS credentials and reduce faking/testing of them. We will be able to deploy different schemes for resisting active probing, identify different schemes to establish user trust. We will learn how to implement methods for evading censor detection and blocking. We will understand various methods for protecting publisher information and current open and active CRS research areas....
