Hey! I said the above first! :-)
Some more on Polymorphic Trusted Agents.
Here are some things that an agent could morph.
1. variable name
2. variable form on disk with self morphing with crypt.
3. variable alphabetic characters to screen. An interrupt can find
standard text characters on screen. Recognizing a character as a
character would be magnitudes harder if icons were substituted for
standard text characters. They could look the same. - helps to defeat
a monitor sniffer.
4. switch characters coming from keyboard to substitute characters
on screen. - defeat keyboard sniffers.
5.Use non operating system sectors on hard disk. - makes invisible
to operating system.
6.Mark sectors on hard disk as defective for operating system and
use them.
7. Trap some Interrupts so that power is shifted to Agent.
8. Other things we will think of later.
Note that most of these tricks are virus tricks.
A well designed shrink wrapped betrayal-ware program may search
for recognizable security programs. A Trusted Agent that was Polymorphic
would be exceedingly difficult to find.
An agent that changed the operating environment (Interrupt traps
etc.) would make betrayal-ware difficult to succeed.
Instead of only writing one malice program to subvert computers,
a tyrant would have to write MANY programs. Maybe an impossible
task.
