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.
