Design and Development of Side Channel Attack Prevention in Quantum Cryptography

Abstract

Cryptography plays a crucial and significant part in key transmission between two users. To send the keys in a secure manner, quantum implementations are used. A recent method of distributing keys across users is known as quantum key distribution. There is a substantial disconnect between quantum key distribution (QKD) theory and practice in this regard. Gadgets no longer meet the security evidence's assumptions. This hole is accessed as an input here. A simple and direct measurement methodology that is independent of the QKD device and is primarily based on any potential flaws and/or failures. A quantum language exchange facet channel that is part of the QKD device. Our simplest technique is experimentally give up to one unpaired parameter for each transmitted pulse. This explains the high dissatisfaction with the source. Also, unlike DI (Device Independent) QKD, Stats leaked from user labs critical to ensuring QKD's security avatar. In that sense, its security is more than what DI QKD offers, but it provides a secret.
