The '''security of [[Advanced Access Content System]]''' has been a subject of discussion amongst security researchers, high definition video enthusiasts, and consumers at large since its inception. A successor to [[Content Scramble System]], the [[digital rights management]] mechanism used by commercial [[DVD]]s, AACS was intended to improve upon the design of CSS by addressing flaws which had led to the [[DeCSS|total circumvention of CSS]] in 1999. The AACS system relies on a [[subset difference tree]] combined with a [[certificate revocation list|certificate revocation]] mechanism to ensure the security of high definition video content in the event of a compromise.

Even before AACS was put into use, security researchers expressed doubts about the system's ability to withstand attacks.
