Hi!
Imagine that with every byte stored on disk image, the emulated
memory and CPU registers we associate a flag indicating if the
byte come from "trusted" source. This information would propagate
with every memory/disk access (data-flow tracking).
Before Qemu would translate a block of code the trusted bits could
be checked to see if the code is "trusted". Of course there are
issues with dynamic loaders, dynamic compilers, etc. And it's not
going to work well with scripted code.
Possible usage:
* building virus-proof PC,
* automate hunting for worms/exploits on Internet.
Opinions?
