So, what really are the risks of inflight use of electronics? In the current scheme of things, there’s not a very high risk. However, we’ve seen that with the iPhone short-out and smoke that occurred on the Australian Airlines flight in November last year, that there are some risks. In the near future as 3D ICs make their way into more and more products, particularly smart phones and tablets, there will be some risk that a cyber-physical attack could occur. What would be the outcome? Done well, a similar scenario to the Australian Airlines incident, multiplied by many tablets and phones, particularly with tablets now allowed for use in the cockpit.
