Problem
Standard cryptographic approaches carry more computational overhead than constrained embedded systems can afford.
Approach
- Designed a lightweight encryption protocol using ARX (Addition, Rotation, XOR) operations for resource-constrained systems
- Implemented secure message encoding and decoding via key-based transformations
