The advent of electronics has transformed medical devices to become
smarter and more convenient to our daily lives. But recent headlines of
hacking point out a consternation of electronics. Medical device
designers need to understand new tools and design techniques that can
prevent hacking and illicit modification.
The issue of hacking
and illicit modification is multi-faceted. Is the software protected
inside a microcontroller? How can access to a chip be eliminated to
prevent hacking? Is there a way to detect code modification? These are
chip-level concerns. There are also system-level issues such as how to
enforce an expiration date and how to authenticate genuine equipment.
We discuss several microcontroller features and modern design techniques that address these concerns. Read full article here.
Refreshing to see an article that does not use Stuxnet as FUD.
However, I don't get it... This supposedly prevents chip level hacking. If an attacker can get in the box and fiddle with chips then he can quite easily remove the "secure" chip and solder on a hacked chip without the security stuff enabled.
