BD+ Successfully Resealed

Posted by Soulskill on from the effort-vs.-reward dept.

IamTheRealMike writes "A month on from the story that BD+ had been completely broken, it appears a new generation of BD+ programs has re-secured the system. A SlySoft developer now estimates February 2009 until support is available. There's a list of unrippable movies on the SlySoft forums; currently there are 16. Meanwhile, one of the open source VM developers seems to have given up on direct emulation attacks, and is now attempting to break the RSA algorithm itself. Back in March SlySoft confidently proclaimed BD+ was finished and said the worst case scenario was 3 months' work: apparently they underestimated the BD+ developers."

  1. Break the RSA algorithm? by Sockatume · · Score: 5, Interesting

    I'm no cryptographer, but isn't this like realising you can't crack a safe, and deciding it'd be easier to invent a machine that will undo the metallic bonds that hold its constituent atoms together?

    No kidding!!! What do you say at this point?

      One potential flaw I just noticed in the way BD+ uses RSA is that they use the public exponent e = 3. This low value is known to open up multiple theoretical attacks as described in section 4 of this paper. Too lazy to register a Doom9 account to post that info on their forums...
