Abstract. In 1997, Lo claimed that Quantum Oblivious Transfer (QOT) is impossible. The result implies severe setback for quantum cryptography. However, it is based on a hypothesis. i.e. to prevent Alice from learning Bob’s choice in the scheme, the reduced density matrices in Alice’s hand for the two cases must be the same. Actually, to prevent Alice from learning his choice, Bob can send the q...

Machine learning (ML)-based methods are being widely explored to predict the quality of transmission (QoT) a lightpath. They expected reduce signal-to-noise ratio margin reserved for lightpath, thus improving spectrum efficiency an optical network. However, many studies on this prediction often based synthetic datasets or obtained from laboratories. As such, these may not accurately represent e...

This work presents efficient connection provisioning techniques mitigating high-power jamming attacks in spectrally-spatially flexible optical networks (SS-FONs) utilizing multicore fibers. High-power are modeled based on their impact the lightpaths’ quality of transmission (QoT) through inter-core crosstalk. Based a desired threshold lightpath’s QoT, modulation format used, length path, as wel...

This paper presents a mathematical framework to provide Quality of Service (QoS) for Grid Applications over optical networks. These QoS parameters include, resource availability, reliability, propagation delay, and quality of transmission (QoT). These multiple services are needed to ensure the successful completion of a Grid job. With the help of link-state information available at each Network...

The potential to operate third-party terminals over multi-domain transparent optical networks attracts operators and customers implement Optical Spectrum as a Service (OSaaS). As infrastructure information cannot always be shared with OSaaS end customers, alternatives off-line Quality of Transmission (QoT) estimation tools are required assess the performance spectrum slot in order estimate achi...

Quantum 2-party cryptography differs from its classical counterpart in at least one important way: Given blak-box access to a perfect commitment scheme there exists a secure 1−2 quantum oblivious transfer. This reduction proposed by Crépeau and Kilian was proved secure against any receiver by Yao, in the case where perfect commitments are used. However, quantum commitments would normally be bas...
