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.
MIT researchers used a technique called elliptic-curve encryption, which relies on a mathematical function to secure transactions. The new chip sets itself apart by being able to handle any kind of elliptic curve, which, in addition to low power use and a high speed of computation, makes it much more useful as an encryption solution.
