Researchers at MIT Invent an Energy Efficient Chip for Internet of Things

On February 13, 2018, Massachusetts Institute of Technology (MIT) revealed that a special microchip has been developed that saves energy.

A new chip has been built by MIT researchers, compatible to function for public-key encryption, which consumes only 1/400 as much power as software execution of the same protocols would. It also uses about 1/10 as much memory and executes 500 times faster. This special-purpose chip uses less power consumption of public-key encryption by 99.75 percent, and increases speed 500 times.

Complicated public- key encryption protocols in computer networks are executed by software. However, in internet of things, which is a multi-connectible network capable of connecting many different sensors integrated in civil structures, appliances, vehicles, manufacturing equipment, and even livestock tags to online servers. The encryption protocols software execution require a high energy and memory space that may be difficult for the sensors to handle.

The researchers are expected to present the chip on the paper to be presented at the International solid-state conference. “Cryptographers are coming up with curves with different properties, and they use different primes,” says Utsav Banerjee, an MIT graduate student in electrical engineering and computer science and first author on the paper. “There is a lot of debate regarding which curve is secure and which curve to use, and there are multiple governments with different standards coming up that talk about different curves. With this chip, we can support all of them, and hopefully, when new curves come along in the future, we can support them as well.”

The internet of things is a large database used daily almost by every human. The details of the same are mentioned in Internet of Things (IoT) Security Market report published by Coherent Market Insights.
