“…Yu et al [24] proposed a heuristic collaborative routing algorithm for partially trusted relay QKD networks, considering relay deployment and remaining key quantities, but with certain deficiencies in handling request disparities. Additionally, some routing schemes [25][26][27][28][29][30] prioritize subsequent processing requests based on criteria such as security levels, business variations, and request arrival times. These schemes can accommodate diverse domain requirements with relatively few restrictions concerning efficiency enhancement considerations.…”

Quantum key distribution (QKD) is a technology that can resist the threat of quantum computers to existing conventional cryptographic protocols. However, due to the stringent requirements of the quantum key generation environment, the generated quantum keys are considered valuable, and the slow key generation rate conflicts with the high-speed data transmission in traditional optical networks. In this paper, for the QKD network with a trusted relay, which is mainly based on point-to-point quantum keys and has complex changes in network resources, we aim to allocate resources reasonably for data packet distribution. Firstly, we formulate a linear programming constraint model for the key resource allocation (KRA) problem based on time-slot scheduling. Secondly, we propose a new scheduling scheme based on graded key security requirements (GKSR) and a new micro-log key storage algorithm for effective storage and management of key resources. Finally, we propose a key resource consumption (KRC) routing optimization algorithm to properly allocate time slots, routes, and key resources. Simulation results show that the proposed scheme significantly improves the key distribution success rate and key resource utilization rate, among others.

“…This breakthrough also encompassed the secure transmission of quantum-protected text and images, as well as quantum-assisted two-way video calling. Routing and resource allocation problems of QKD links along with AI/ML techniques for solving the complex decision-making problem of QKD-secured optical networks are studied by IIT Indore [63]. The Fiber-Optics, Quantum and Nano-Photonics (FOQNP) group from IIT Kharagpur works on quantum communication for satellite communication, key distribution and quantum random number generation, both theoretically and experimentally [64].…”

With the increasing use of internet and mobile phones, the capacity of the backbone optical communication link has been continually growing across the world and especially in India. The total optical fiber cable deployed for the BharatNet initiative of Government of India is expected to increase from 3.4 million km to 5 million km in 2024-25 just for providing lastmile connectivity. Considering this deep proliferation, this article attempts to capture the diverse research carried out in India in the domain of optical communication.

“…Various existing studies [20,22,[27][28][29][30][31] have addressed the resource assignment problem of QKD-enabled ONs [22]. Different routing and resource assignment strategies were designed for both static (where lightpath requests are known in advance) [20] and dynamic (where lightpath requests are not known in advance) [22] traffic scenarios.…”

In QKD‐enabled optical networks (QKD‐enabled ONs), fragmentation is one of the serious issues which can be mitigated through appropriate management of network resources. Thus, efficient allocation of network resources during routing and resource assignment is important to minimise the impact of time slot fragmentation in the quantum signal channel (QSCh) of QKD‐enabled ONs. The authors address the fragmentation problem in the QSCh and propose a new fragmentation‐suppressed routing and resource assignment (FS‐RRA) approach. To evaluate the performance and to analyse the effect of time slot fragmentation in QSCh of QKD‐enabled ONs, the proposed FS‐RRA approach is compared with two existing resource assignment approaches, namely, the first‐fit (FF) and random‐fit (RF) for two different networks. Simulation results show that the proposed approach reduces fragmentation by 2.97% and 6.69% for NSFNET and 1.77% and 5.91% for UBN24 in terms of external fragmentation compared to FF and RF, respectively. Furthermore, the proposed approach reduces blocking by 4.03% and 14.28% for NSFNET and 2.61% and 13.44% for UBN24 and improves resource utilisation up to 3.44% and 5.96% for NSFNET and 3.08% and 7.64% for UBN24 compared to FF and RF, respectively.
