Massachusetts Institute of Technology (MIT) researchers say they have developed an encryption system that performs schemes that classical computers can use, but quantum computers cannot crack.

The new system performs the scheme on a chip small enough and energy-efficient enough to guard battery-powered nodes on the Internet of Things from future quantum attacks.

The researchers used lattice-based cryptography and an efficient pseudo random number generator to reduce the computational load.

To fit the encryption algorithm, the random numbers must fit certain statistical properties. That required three different algorithms designed to reject numbers that did not fit.

The researchers chose algorithms that produced significant energy savings when implemented in silicon.

Next, the researchers want to ensure that the chip is immune to side-channel attacks, which can steal data indirectly through things such as changes in a chip's power consumption, how it radiates energy, or how long certain actions take.
