Encryption Mechanisms for Digital Content Distribution

Abstract

Controlling and protecting the flow of digital content poses unique challenges for cryptographic design. In such settings the most common adverse behavior comes from within the system. Standard adversarial models of encryption and other primitives become moot at this level of adversity. The repeated failures of traditional cryptographic and security methods to solve these problems in practice, motivated a new class of cryptographic constructs that include broadcast encryption, traitor tracing, fingerprinting codes and others. In this lecture we will introduce this new cryptographic toolset for building encryption mechanisms for digital content distribution and demonstrate some recent constructions.
