Problem Statement
Traditional cryptographic methods may be vulnerable to quantum attacks in the future.
Quantum Key Distribution (QKD) aims to provide secure communication channels by
using the principles of quantum mechanics to detect eavesdropping.
Abstract
This project focuses on implementing Quantum Key Distribution for secure
communication. The goal is to develop a system that enables the exchange of
cryptographic keys between two parties using quantum properties. The security of the
communication will be based on the fundamental principles of quantum mechanics,
providing a theoretically unbreakable method for secure key exchange.
Outcome
A working prototype demonstrating the feasibility of Quantum Key Distribution,
enhancing the security of communication channels against potential quantum attacks.
Reference
The security strength of key distribution of most conventional cryptography is relied on mathematical complexity and the irrational time needed to break the algorithm. But it will be ineffective if the secret key distribution procedure is weak. In 1994 Peter Shor proposed an algorithm that can factorize great integer number efficiently by using principle of quantum computer, this algorithm poses a threat to some of the conventional cryptography. Recently, Quantum Key Distribution (QKD) is drawing much attention of researcher as a solution of that problem of key distribution. Theoretically, QKD have been proven can be provide unconditionally secure communication based on quantum mechanics laws. In this article we survey the QKD protocols.
