BEdX25519: A lightweight authenticated key exchange protocol for secure IoT device-to-device (D2D) communication using blockchain and elliptic curve cryptography

BEdX25519 is a lightweight authenticated key exchange protocol (a method for two devices to securely agree on encryption keys) designed for IoT (Internet of Things) devices to communicate directly with each other using blockchain (a distributed ledger technology) and elliptic curve cryptography (a type of mathematical encryption based on curves). The protocol aims to make secure device-to-device communication more efficient for resource-constrained IoT systems.
