The Internet of Things hasn't ever been super secure. Hacked smart devices have been blamed for web blackouts, broken internet, spam and phishing attempts and, of course, the coming smart-thing apocalypse. One of the reasons that we haven't seen the same sort of encryption as the web affords, however, is that such protection is energy-intensive. MIT is working on a new chip, however, to perform this sort of public-key encryption that only uses 1/400 as much power as a software solution would. In addition, the chip uses about 1/10 as much memory and executes processes 500 times as fast.
