Home Media Magazine has an article in their digital edition quoting consultant Richard Doherty of the Envisioneering Group regarding his views on BD+ security for Blu-ray. BD+ is the added protection layer adopted by the Blu-ray consortium to increase the overall security of Blu-ray distributed content.
[Doherty] said BD+ offers four times the safeguards on top of AACS against priracy.... BD+, unlike AACS, which suffered a partial hack last year, won't likely be breached for 10 years, Doherty said, and if so, the damage would affect one film and one player.
Some have objected to Dohery's views, suggesting it's only a matter of time before the hacker community breaks BD+, for example, this blogicle on EngadgetHD.
Of course, he did mention that BD+ offered up "four times the safeguards on top of AACS against piracy," so we'll give the oh-so-inundated hackers about four times longer than usual to prove this guy wrong.
The issue is not whether BD+ will be compromised. That's guaranteed. Rather, the main points are:
- the level of effort required to compromised a BD+ protected disc is significantly higher than discs with AACS alone;
- security breaches are limited;
- it's difficult to transfer expert knowledge gained in the breach to ordinary users via a software program; and
- since BD+ is programmable, it's much easier to implement countermeasures to actual security violations than is AACS, which is mainly a sophisticated key revocation system.
