“…The work of Elboukhari et al [21] presents a new approach to combining a quantum key distribution protocol with classical security protocols, and defines how they integrate QKD into the TLS protocol. Using the BB84 protocol, they have defined an extended TLS protocol that enhances the security of the TLS protocol as described in RFC5246.…”

The BB84 quantum key distribution (QKD) protocol is based on the no-cloning quantum physic property, so if an attacker measures a photon state, he disturbs that state. This protocol uses two channels: (1) A quantum channel for sending the quantum information (photons polarized). (2) And a classical channel for exchanging the polarization and the measurement information (base sets or filters). The BB84 supposes that the classical channel is secure, but it is not always right, because it depends on the methods used during the communication over this channel. If an eavesdropper gets the sender or the receiver filters or both of them, he can leak some or all bits of the constructed key. In this context, we contribute by creating a protocol that combines the BB84 protocol with an improved scheme of NTRU post-quantum cryptosystem, which will secure the transmitted information over the classical channel. NTRU is a structured lattice scheme, and it is based on the hardness to solve lattice problems in Rn. Actually, it is one of the most important candidates for the NIST post-quantum standardization project.

“…The protocols periodically request fresh keying material and fall back to conventional key exchange if QKD is not operational. Another option for TLS integration is suggested in [4], where the handshake protocol is modified so that QKD is carried out in the middle of the handshake, and a configuration protocol is added to agree on parameters such as the key length. Our own proposal relies upon a pre-established QKD channel such that QKD-generated key material is continuously made available for each party, and takes advantage of the existing pre-shared secret key standards to avoid significant re-work in the protocols; the transmitted fields relating to the pre-shared secret are appropriately modified so that both parties obtain the same quantum-generated key, and significant re-work to the protocols are avoided.…”

Quantum Key Distribution (QKD) is a means of generating keys between a pair of computing hosts that is theoretically secure against cryptanalysis, even by a quantum computer. Although there is much active research into improving the QKD technology itself, there is still significant work to be done to apply engineering methodology and determine how it can be practically built to scale within an enterprise IT environment. Significant challenges exist in building a practical key management service for use in a metropolitan network. QKD is generally a point-to-point technique only and is subject to steep performance constraints. The integration of QKD into enterpriselevel computing has been researched, to enable quantum-safe communication. A novel method for constructing a key management service is presented that allows arbitrary computing hosts on one site to establish multiple secure communication sessions with the hosts of another site. A key exchange protocol is proposed where symmetric private keys are granted to hosts while satisfying the scalability needs of an enterprise population of users. The key management service operates within a layered architectural style that is able to interoperate with various underlying QKD implementations. Variable levels of security for the host population are enforced through a policy engine. A network layer provides key generation across a network of nodes connected by quantum links. Scheduling and routing functionality allows quantum key material to be relayed across trusted nodes. Optimizations are performed to match the real-time host demand for key material with the capacity afforded by the infrastructure. The result is a flexible and scalable architecture that is suitable for enterprise use and independent of any specific QKD technology.

Background: A major episode of lead poisoning caused by lead-adulterated opium occurred in Iran in 2016. Patients were removed from exposure and treated with chelating agents. A subset of those patients was evaluated in this follow-up study to evaluate treatment efficacy in relation to patient outcome. Methods:Between March 2016 and December 2017, thirty-five male cases of lead poisoning due to ingestion of lead-adulterated opium were followed for two years. There are three patient groups: 1) those who abstained from opium use; 2) those who continued to use potentially contaminated opium; and 3) those who abstained from opium and were placed on maintenance therapy. Maintenance therapy included: methadone and opium tincture, offered by the Opioid Maintenance Therapy (OMT) clinics. Amongst the three patient groups Blood Lead Levels (BLL), complete blood count, and kidney and liver function tests were compared. Findings:The results of BLL, hemoglobin, hematocrit, and aspartate aminotransferase were significantly different between the admission time and follow-up. Of the three patient groups, no difference was detected in these measures. Conclusions:Treatment of lead poisoning combined with OMT proved an effective method to prevent recurrent lead poisoning.
