Energy-efficient encryption for the IoT

Most sensitive web transactions are protected by public-key cryptography and in computer networks, they’re executed by software. However, that won’t work in the IoT, an envisioned network that would connect many different sensors to online servers. MIT explains that embedded sensors that need to maximise battery life can’t afford the energy and memory space that software execution of encryption protocols would require. The new chip uses elliptic-curve encryption which is said to be able to handle not just specific, but any elliptic curve. “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. “There is a lot of debate regarding which curve is secure and which curve to use and there are multiple governments with different standards comin...
