Entanglement-based Key Distribution Protocols

This white paper outlines the implementation and scaling of key distribution protocols, focusing on entanglement-based methods. It compares the BBM92 protocol with the BB84 protocol, discussing their theoretical security equivalence and practical differences. The document explains the process of securely establishing a shared secret key between two parties, Alice and Bob, using quantum technology. It details the steps involved in key distribution, including the generation of correlated raw keys through quantum communication and the subsequent classical processing to derive shared secret keys. The paper also addresses the challenges posed by quantum computers to traditional encryption methods and presents quantum secure protocols as a solution. These protocols leverage quantum mechanics principles to ensure secure communication against eavesdroppers. Additionally, the document discusses the compatibility of quantum secure protocols with post-quantum cryptography, emphasizing their role in future secure networking applications.
