Question

Why is the Secure Audio Path Model necessary?

a.

To encrypt audio files

b.

To control the flow of unencrypted copyrighted audio within Windows

c.

To protect the decryption key for audio files

d.

None of the above

Posted under Reverse Engineering

Answer: (b).To control the flow of unencrypted copyrighted audio within Windows Explanation:The problem is that anyone can write a simulated audio device driver that would just steal the decrypted content while the media playback software is sending it to the sound card. The Secure Audio Path ensures that the copyrighted audio remains in the kernel and is only transmitted to audio drivers that were signed by a trusted authority.
