Lightweight Cryptography

Definitions

1. Cryptographic algorithms and designs optimized for constrained environments such as small microcontrollers, sensors, tags, and battery-powered devices with limited memory, CPU, or energy budget. Lightweight cryptography aims to preserve strong security while fitting hardware that cannot comfortably run heavier standard implementations.

   In plain English: Cryptography designed to work efficiently on small, low-power devices.

   Example: "The device used lightweight cryptography because its microcontroller had almost no RAM and operated on a tiny battery."
