This is really cool. A new chip within a computer architecture that focuses on the "undefined semantics" of the computer's architecture - location, format, and program code etc., and "churns" its (moves their "locations") every 50ms. Several thousand times faster than even the fastest hacking programs and impossible for humans. IOW, computers become unhackable. https://news.umich.edu/unhackable-new-chip-stops-attacks-before-they-start/
Until someone hacks the chip itself? Assuming they can achieve 100% reliability, that sounds exciting. But that's a big assumption. It sounds like something that could render a computer unusable as well. Also, what is the impact on speed and the power requirements?
the 50ms churn interval was selected (it's adjustable) to limit the impact of overall performance by 1%. I believe the performance hit isn't linear, it's exponential. As I understand the concept since, the churn is random, it's not possible with today's technology to follow it by external tracking. Way too much horsepower needed and too much lag in communications.
This is brilliant. I would expect to see this soon as the stakes are so high. I wonder if something like this can eventually protect against ransomware.
