The content code is executed on a virtual big endian DLX-like processor interfacing 4MB of memory. This program which can be found inside the BDSVM directory of a BD+ protected disc is called content code. By varying the instruction filter at runtime, the compiler can force an adversary to trace through the code at runtime before they can fully disassemble it. To prevent simple, static disassembly of the BD+ code, an instruction filter is available that can perform an XOR operation on an opcode before executing it. A TRAP instruction is used to allow the virtual machine host to perform more complex actions as system calls. It has 32 32-bit registers available for use. Both SlySoft (now RedFox) and members of the Doom9 forum have reverse engineered the virtual machine specification, however.Īccording to the reverse-engineered specification, the virtual machine consists of a 32-bit big endian DLX like processor with 4MB of RAM. A list of licensed adopters is available from the BD+ website. The specifications of the BD+ virtual machine are only officially available to licensed device manufacturers. These programs can then be included in all new disc releases.
If a playback device manufacturer finds that its devices have been hacked, it can potentially release BD+-code that detects and circumvents the vulnerability. Parts of the content will not be viewable without letting the BD+-program repair it.

execute native code, possibly to patch an otherwise insecure system.verify that the player's keys have not been changed.Every licensed playback device manufacturer must provide the BD+ licensing authority with memory footprints that identify their devices. examine the host environment, to see if the player has been tampered with.It allows content providers to include executable programs on Blu-ray Discs. 3 Reverse engineering and emulation of BD+ implementationsīD+ is effectively a virtual machine embedded in authorized players.On 7 July 2011, Irdeto acquired BD+ content protection technology for Blu-ray discs from Rovi Corporation.

On 19 November 2007, Macrovision announced that it planned to acquire the SPDC technology (including patents and software code) from CRI for US$45 million in cash plus stock warrants. The copy protection scheme was to take "10 years" to crack, according to Richard Doherty, an analyst with Envisioneering Group. Several studios cited Blu-ray Disc's adoption of the BD+ anti-copying system as the reason they supported Blu-ray Disc over HD DVD. īD+ played a pivotal role in the format war of Blu-ray and HD DVD. While BD+ has not stemmed the flow of "cracked" high-definition content, it has made it necessary for those who wish to copy Blu-ray movies to reinvest resources to break each new version of security code. Its intent was to prevent unauthorized copies of Blu-ray discs and the playback of Blu-ray media using unauthorized devices. and is based on their Self-Protecting Digital Content concept. It was developed by Cryptography Research Inc. Component of the Blu-ray Disc digital rights management systemīD+ is a component of the Blu-ray Disc digital rights management system.
