"EJAFA_PROTOCOL: A CUSTOM INC SECURE PROTOCOL" presents a cryptographic solution tailored for lightweight devices, striking a delicate balance between security and efficiency. The protocol incorporates modern cryptographic primitives, including X25519 for key exchange and ChaCha20 for encryption, while adhering to established RFC standards. The report explores the protocol's design, implementation over various network protocols, and its performance characteristics. A key feature of the protocol is its adaptability to resource-constrained environments without compromising on security. This work contributes to the evolving landscape of secure communication protocols, providing a robust solution for practical deployment across a spectrum of applications.
