We introduce a new integral method for Quantum Key Distribution to perform sifting, reconciliation and amplification processes to establish a cryptographic key through the use of binary structures called frames which are capable to increase quadratically the secret key rate. The method can be implemented with the usual optical Bennett-Brassard (BB84) equipment allowing strong pulses in the quantum regime.

Cryptographic Key

We introduce a new integral method for Quantum Key Distribution to perform sifting, reconciliation and amplification processes to establish a cryptographic key through the use of binary matrices called frames which are capable to increase quadratically the secret key rate. Since the eavesdropper has no control on Bob’s double matching detection events, our protocol is not vulnerable to the Intercept and Resend (IR) attack nor the Photon Number Splitting (PNS) attack. The method can be implemented with the usual optical Bennett–Brassard ( B B 84 ) equipment allowing strong pulses in the quantum regime.

Encryption Decryption

Quantum Key Distribution (QKD) has been developed over the last decade; QKD addresses the challenge of a securely exchanging cryptographic key between two parties over an insecure channel where there are two parties that simultaneously generate and share a secret key using the polarization of quantum states of light by applying the phenomena of quantum physics. The integration of QKD protocol with public key cryptography for securely exchanging the encryption/decryption keys is proposed and simulated, the simulation results evaluate the work of the existing and proposed protocol taking into account different measures. Finally, a short security analysis is given to show the difference between the proposed protocol and its counterparts.

Photon Source

We analyze theoretically the performance of four-state quantum key distribution protocols implemented with a realistic heralded single-photon source. The analysis assumes a noisy model for the detector heralding generation of individual photons via spontaneous parametric down-conversion, including dark counts and imperfect photon number resolution. We identify characteristics of the heralding detector that defines the attainable cryptographic key rate and the maximum secure distance. Approximate analytical formulas are applied to multiplexed detection and compared with results of numerical calculations.
