Encryption for digital content Préface :
Cryptography is an area that traditionally focused on secure communication, authentication and integrity.
In recent times though, there is a wealth of novel fine-tuned cryptographic techniques that sprung up as cryptographers focused on the specialised problems that arise in digital content distribution. These include fingerprinting codes, traitor tracing, broadcast encryption and others. This book is an introduction to this new generation of cryptographic mechanisms as well as an attempt to provide a cohesive presentation of these techniques.
