Cryptology for Digital Tv Broadcasting

Primary tabs

Macq, Benoît [UCL] Quisquater, Jean-Jacques [UCL]

Digital TV broadcasting needs new cryptological tools for conditional access, copyright protection and image authentication. The aim of this paper is to overview the corresponding systems' features. The description of a conditional access system is given. It is shown that equitable systems need the use of a Trusted Third Party. The design of efficient copyright protection by watermarking images and image authentication by signatures are also briefly discussed.
