Quantum Secure Communication Using BBM92 Protocol

This white paper discusses the implementation of the BBM92 protocol for secure communication through entanglement-based networking. It outlines the urgent need for quantum secure communication in light of vulnerabilities posed by potential Harvest Now Decrypt Later (HNDL) attacks, where sensitive data can be intercepted and decrypted in the future. The paper details the operational steps of the BBM92 protocol, including entanglement distribution, key sifting, eavesdropper detection, information reconciliation, and privacy amplification. It explains how entangled photons are used to create symmetric keys and how these keys ensure secure communication. The document emphasizes that the security of the BBM92 protocol relies on the principles of quantum physics rather than computational assumptions, making it resilient against future advancements in quantum computing. The paper also addresses practical considerations for organizations looking to integrate quantum networking into their security frameworks, highlighting the importance of protecting sensitive communications across various sectors.
