Study and Implementation of 3 Stage Quantum Cryptography in Optical Networks
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 9
Abstract
This paper presents a quantum protocol based on public key cryptography for secure transmission of data over a public channel. The security of the protocol derives from the fact that Alice and Bob each use secret keys in the multiple exchange of the qubit. Unlike the BB84 protocol and its many variants where the qubits are transmitted in only one direction and classical information exchanged thereafter, the communication in the proposed protocol remains quantum in each stage. In the BB84 protocol, each transmitted qubit is in one of four different states; in the proposed protocol, the transmitted qubit can be in any arbitrary state. Disparate and heterogeneous networks will be a growing reality in the future. Additionally, some of the regulatory, national interest, and security requirements might force a geographic boundary between networks.
