Hard to clone Micros.

Started by Unbeliever June 10, 2005
I need a hard to clone Micro.  I'd appreciate any input from the illuminati
that inhabit this corner of cyberspace.  I am aware that PICs with the
security fuses blown are very easy to clone using invasive techniques.  I
have seen websitest that offer to "recover lost code" from AVRs, Philips
8051's and others.

Do any of you guys have any experience in what's easy and what's hard to
read and/or clone in the current range of reasonably priced (sub US$10)
micros?

do you have some ressources that explain how to clone micros (you wrote 
"very easy to clone", how easy is it?)? I would be very interested into 
knowing the principles.

Even some bookmarks where it is "offered" to recover lost code may be 
interested.

Best regards

Depends on the type of clone-attack you expect. The most design effort in this area, is done in smart card controllers, so I'd look in that sector. -jg
