Deployment of security vulnerabilities in Quantum Cryptographic & QKD using B92 protocol

Abstract

Secure communication has always been a key concern while sharing information between two parties. Traditional and lightweight cryptography primitives and protocols are insecure against quantum attacks. The objective of cryptography is to ensure confidentiality, integrity, authentication and non-repudiation between both parties. Quantum key distribution is a safe and sound method for communication between two parties to share their information. However early applications with applied limitations lead to open ambiguities, permitting an eavesdropper to breach the security of quantum cryptographic system. This research proposes a framework for quantum key distribution using B92 protocol. The B92 protocol allows two different users A to share their polarized photons with high security and without any interruption of Eavesdropper. While B92 protocol generates a secrete key, that is known to just sender and receiver. The use of QuVis framework can provide this secure communication and photons are transferred to Bob securely without any Eavesdropper.
