A Performance-Security Balanced Framework for Lightweight Cryptography Incorporating Hardware Acceleration and Adaptive Key Exchange in IoT Environments
A performance–security balanced framework that specifies an adaptive key exchange protocol based on X25519 with HKDF-SHA256, an authenticated encryption using ChaCha20-Poly1305 or AES-GCM with strict nonce/counter management, and hardware acceleration on ARM Cortex-M4 and FPGA modules to reduce computation and energy o...
