Aiming at the problems of low success rate, delay, and high communication cost in distance English teaching resource sharing, this paper puts forward a method of distance English teaching resource sharing based on Internet O2O mode. Based on the model of distance English teaching resource sharing, this paper designs four processes: query, reply, resource substitution, and resource sharing optimization. Experimental results show that the proposed method can achieve high success rate of resource sharing, low latency, communication cost, and high transmission efficiency. Therefore, it is an effective method.

“…Based on existing networks, the MDI-QKD [ 13 ] network with the Hybrid Trusted and Untrusted Relay (HTUR) extends the transmission distance and improves security further, where untrusted relays do not rely on any assumptions on measurement. We note the introduction of the Quantum Key Pool (QKP) [ 4 , 21 , 22 , 23 ] in QKD networks. The secret keys generated between QKD node pairs are stored in the QKP temporarily to reduce the waste of secret keys.…”

The Measurement-Device-Independent-Quantum Key Distribution (MDI-QKD) has the advantage of extending the secure transmission distances. The MDI-QKD combined with the Hybrid-Trusted and Untrusted Relay (HTUR) is used to deploy large-scale QKD networks, which effectively saves deployment cost. We propose an improved scheme for the QKD network architecture and cost analysis, which simplifies the number of QKD transmitters and incorporates the quantum key pool (QKP) in the QKD network. We developed a novel Hybrid-QKD-Network-Cost (HQNC) heuristic algorithm to solve the cost optimization problem. Simulations verified that the scheme in this paper could save the cost by over 50 percent and 90 percent, respectively.

“…Niu et al [ 10 ] proposed a scheme of key size-driven wavelength assignment (KSD-WA), which reclaims the wavelength segments to transmit the quantum signals, thus, the wavelength of the quantum channels may require reconfiguration at different time slots if required. Taking the QKP technique in the QKD network into account, KSD-WA optimizes it with a heuristic algorithm and designs a deep reinforcement learning-based algorithm to optimize the fragment selection.…”

In the era of the interconnection of all things, the security of the Internet of Things (IoT) has become a new challenge. The theoretical basis of unconditional security can be guaranteed by using quantum keys, which can form a QKD network-based security protection system of quantum Internet of things (Q-IoT). However, due to the low generation rate of the quantum keys, the lack of a reasonable key allocation scheme can reduce the overall service quality. Therefore, this paper proposes a dynamic on-demand key allocation scheme, named DDKA-QKDN, to better meet the requirements of lightweight in the application scenario of Q-IoT and make efficient use of quantum key resources. Taking the two processes of the quantum key pool (QKP) key allocation and the QKP key supplement into account, the scheme dynamically allocates quantum keys and supplements the QKP on demand, which quantitatively weighs the quantum key quantity and security requirements of key requests in proportion. The simulation results show that the system efficiency and the ability of QKP to provide key request services are significantly improved by this scheme.
