“…SARG04 Protocol.Proposed by V. Scarani in 2004, this protocol differed from BB84 in terms of photon sources as it utilized attenuated laser pulses instead of SPS. At the quantum processing level, SARG04 was viewed as equivalent to BB84 by Chi-Hang Fred Fung[7]. Theoretically, SARG04 appeared to be a more feasible practical implementation of PM-QKD but the experimental results in[8]established that the key generation rate of SARG04 is lesser than half of BB84.Decoy-State Protocol.This protocol was proposed by Hwang to provide a solution to the inherited PNS vulnerability[1]of BB84 due to SPS.…”

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.

This study proposes an application plan to enhance the security of data transmission in the highway freight information system. The plan utilizes quantum communication technology to encrypt and transmit sensitive data. It involves the use of a quantum key cloud terminal for the unified management of quantum keys and providing key services for the highway freight information system. The system can be accessed through the quantum key cloud service platform. By securely using mobile terminal quantum keys, the overall security of the road freight information system is improved. This scheme ensures the security of the entire system by using a quantum encryption key that is generated only once. The plan defines a quantum key management server and a quantum key cloud platform to manage terminals and quantum keys respectively. These components work together with other hardware facilities and software to produce and distribute quantum keys, ensuring the secure transmission of key information.

“…Quantum Key Distribution (QKD) became a topic of high relevance when the scientific community realised the potential of the upcoming quantum computers. Nowadays cryptography mechanisms rely on the complexity of mathematical factorization problems, that would take years to be solved by a generic computer [Sharma 2019]. However, it was shown by [Shor 1999] that a quantum computer is able to solve, for example, the integer factorization problem in a matter of minutes, threatening the security of our information [Cheng 2017].…”

In this work, a fully functional polarization-encoding quantum key distribution system (QKD) is demonstrated. At the transmitter side, the polarization states are prepared using an algorithm to determine the voltages to be applied on the electronic polarization controller (EPC), to generate up to four polarization states. At the receiver, a second EPC is used to perform the basis alignment. The symbol synchronization is achieved using a reference optical signal that is wavelength division multiplexed with the quantum signal which carries the polarization-encoded qubit. Frame synchronization is achieved at a protocol level. The presented QKD system works at a repetition rate of 500 Hz, with an average quantum bit error rate of 1.35%.
