Light-weight Crypto for IoT

While AES and SHA work well together within computer systems, they struggle in an IoT/embedded world as they take up: too much processing power; too much physical space; and consume too much battery power. So NIST outlines a number of methods which can be used for light-weight cryptography, and which could be useful in IoT and RFID devices [1]. They define the device spectrum as:

• Conventional cryptography. Servers…
