Different lightweight cryptography:
- Lightweight cryptography: it is a cryptographic algorithm intended to secure data transmission between resource-constrained devices.
- Resource-constrained: Resource-constrained devices are low resource devices like low battery power, low memory, and low processing capability which is difficult to support conventional cryptography algorithms.
- Example lightweight devices:
- Fitness Tracker
- Nest Smart Thermostat
- Canary Smart Security System
- Scanomat Topbrewer
- WeMo Switch Smart Plug
- Philips Hue Smart Bulbs
- Kolibree Smart Toothbrush
- Samsung SmartThings Hub
Performance metrics for lightweight cryptography
(as per NIST standard)
- For Hardware implementation
-
- Circuit size(power consumption and cost) – eg: RFID and low-cost sensors.
-
- Energy eg: Medical devices and battery-powered devices.
-
- Latency (real-time performance) eg: Memory encryption, on-vehicle device, industrial I/O device control.
- For Embedded software implementation
-
- Memory size (ROM/RAM) eg: Electrical home appliances, sensors, and on-vehicle devices.
