“…In the ⊠ basis, the notations ↗ and ↖ stand for single photon being polarised at 45 and 135 and represent the logical 0 and 1, respectively. In this circuit, we consider the presence of an eavesdropper capable of powering an Intercept and Resend Attack (IRA) and a Beam Splitter Attack (BSA) [12]. For security purposes of the BB84, we assume that Eve has enough technological power and we integrate a realistic optimised attack strategy that combines both IRA and BSA (stage 2 of Fig.…”

“…The set of the SPSs, QC, BSs, PBSs and SPDs do introduce some extra errors to the transmitted qubits, which will affect the sifted key, even in the case where Alice and Bob make identical choices of basis. Since it is hardly complicated to estimate the success probability of the most general attack technique, we consider the optimised attack strategy where Eve is permitted to attack by any manner allowed by quantum mechanics [12].…”

“…To our knowledge, no work addressed the assessment of the success probability of the entire circuit that implements the QKD, when based on imperfect photonic devices and using probabilistic SPS for single photon emission. We have already proposed a circuit realisation of the BB84 protocol based on single and two qubits gates [12]. Then, we suggested a more secure version that is based on Quantum Dense Coding (QDC), we proposed the circuit that realises the optimised BB84 version when using a specific probabilistic CNOT gate model (providing a success probability of (4/27)) and optimised heralded SPS.…”

“…, γ 3 = P SPD 1 B , P SPD 2 B and γ 4 = P SPD 3 B , P SPD 4 B . Let us denote the success probability of detecting a photon by an SPD as P SPD and it is obtained by (15) where P SPD e is the probability of having an erroneous detection, given by the probability of having a dark count over the total probability of detection, which is obtained as [1,12]…”

Data protection and information security have been the essence of communication in today's digital era. Authentication and secrecy of secure communication are achieved using key-based cryptographic primitives; the security of which significantly relies upon the underlying computationally complex mathematics. Moreover, these existing cryptographic primitives are considered to be non-deterministic on the basis of the existing computational capabilities. However, the considerable advancements in the development of quantum computers have significantly enhanced parallel computations; thereby, posing a great threat to these existing encryption primitives. Thus, in the future, the physical manifestation of a large successful quantum computer is likely to break all the existing public-key encryption algorithms in no time. This has led to a remarkable surge of interest in propelling quantum mechanics into existence; subsequently, leading cryptographers to research various viable domains to offer quantum-resistant secure communications. Resultantly, quantum cryptography/quantum key distribution has emerged as a futuristic replacement for classical cryptography as it offers unconditionally secure communication along with the inherent detection of any unintended user. Thus, keeping in view the significance of this relatively newer domain of cryptography, this research focuses on presenting a consolidated review of the various Quantum Key Distribution (QKD) protocols. A comparative analysis of the working mechanism of the prominent QKD protocols is presented along with an overview of the various emerging trends that have been proposed to optimize the implementational efficiency of the BB84 protocol.
