“…As indicated in Section IV-B, authenticated packets in QKD post-processing can be used to effectively exchange information about the geographical position of nodes. Although several experiments have been conducted regarding mobile QKD networking [61][62][63][64][65], due to the high sensitivity of quantum equipment to various environmental factors 5 and relatively low key generation rates in free-space QKD links [23,58,[67][68][69], in this paper we assume that QKD networks are composed of static nodes representing secure access points 6 . We follow the idea "the greater the distance separating two nodes, the slower they appear to be moving with respect to each other" outlined in [70] to implement caching in GPSRQ, which is discussed further below.…”

In recent years, noticeable progress has been made in the development of quantum equipment, reflected through the number of successful demonstrations of Quantum Key Distribution (QKD) technology. Although they showcase the great achievements of QKD, many practical difficulties still need to be resolved. Inspired by the significant similarity between mobile ad-hoc networks and QKD technology, we propose a novel quality of service (QoS) model including new metrics for determining the states of public and quantum channels as well as a comprehensive metric of the QKD link. We also propose a novel routing protocol to achieve high-level scalability and minimize consumption of cryptographic keys. Given the limited mobility of nodes in QKD networks, our routing protocol uses the geographical distance and calculated link states to determine the optimal route. It also benefits from a caching mechanism and detection of returning loops to provide effective forwarding while minimizing key consumption and achieving the desired utilization of network links. Simulation results are presented to demonstrate the validity and accuracy of the proposed solutions.

The dynamic spectrum access (DSA) paradigm of the cognitive radio (CR) contributes intrinsic security capability to the CR network by hiding information in the unpredictable spectrum access patterns. This paper formalizes the frequency hopping DSA (FH-DSA)-based cryptography by introducing the model of dynamic bit (dybit), whose state indicates both the binary value and the DSA strategy. Taking advantage of uncertainty of the dybit state, FH-based key distribution (FH-KE) mechanisms are proposed to establish secrets among communication attendants. Based on the group FH-KE (GKE), a confidentiality-oriented DSA scheme, GKE-DSA is developed to realize the FH-DSA cryptography-based secure data communication. The GKE-DSA can conceal the DSA strategy of each communication link from others while limiting the data packet collisions through GKE-based negotiation.
