Yep, Susan, it's definitely a good plot! I would love to read a myestery on that premise!

I am just imagining a scenario where the hacker hijacks a high profile person and using the same technique of touch-to-access is able to generate that key to be able to reprogram the implants in a malicious way.

It could become a tool to get some ransom out of hijacking the high profile people!

The good doctor and her student told me that there is much concern that high-profile people could become targets of hackers because of the wide availability of wireless surveilance equipment. They are currently hawking their algorithm to makers of pacemakers, insulin pumps, defibrillators, neural implants, and drug delivery systems.

Beyond implants, since the heartbeat is being used as a random number generator, it is conceivable that the technique could be used in other forms ofr cryptography where the sender and receiver automatically generate the same secret key.

You are probably right, but the Secret Service was allegedly concerned about Dick Cheney having his pacemaker hacked and is specifically mentioned in a 2008 report in the New York Times:

A Heart Device Is Found Vulnerable to Attackers

Never thought a person's pacemaker could be hacked!! :)

Great work by the Professor and the doctoral candidate of the Rice university!! Can this kind of encryption technique be applied into other fields for secured systems?

Perhaps it is a blot for a good murder mystery.

Similar to the car hacking article a few weeks ago.  These devices should have some security, but it seems unlikely that anyone would go to the trouble to hack in to your pacemaker.  Of course, with Obamacare, you probably won't be allowed to get one anyway.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
