[comp.arch] computer security

Early this month I posted a short article which asked
a few questions on the subject computer security.
I got some good input --- thanks --- and some
discussions have also been stimulated here on the net.

OK -- now I would like to add a little focus.  Most
systems in the future that address security will
have some way to validate a user's ability to access that
system.  Passwords alone will not suffice.  there will
be some electronic key with some possible biometric
characteristic evaluated.  The key's and readers will
have some microcontroller controlling the actual transaction.

What should this little beast consist of????

	* what kind of memory (Eprom, EE other)
	* how much memory
	* what sort of provisions for memory
	  protection.
	* what kind of I/O --- rs232, other communication
	* what sort of performance
	* should this have some DSP
	  characteristics

This part could also be used in cable TV scramblers as well
as other non-computer related products.

I would be interested in hearing from others working in this area.
I am interested in understanding what access methods are being
looked at, and IF this is a likely application for a microcontroller
that has some security features built-in, what should this
device look like.  

replies via email will be appreciated

thanx in advance
