Quantum Multi-User Broadcast Protocol for the “Platform as a Service” Model

Abstract

Quantum Cloud Computing is the technology which has the capability to shape the future of computing. In “Platform as a Service (PaaS)” type of cloud computing, the development environment is delivered as a service. In this paper, a multi-user broadcast protocol in network is developed with the mode of one master and N slaves together with a sequence of single photons. It can be applied to a multi-node network, in which a single photon sequence can be sent to all the slave nodes simultaneously. In broadcast communication networks, these single photons encode classical information directly through noisy quantum communication channels. The results show that this protocol can realize the secret key generation and sharing of multiple nodes. The protocol we propose is also proved to be unconditionally secure in theory, which indicates its feasibility in theoretical application.

Quantum secret sharing between multiparty and multiparty without entanglement

Fengli Yan, Ting Gao

We propose a quantum secret sharing protocol between multiparty ($m$ members in group 1) and multiparty ($n$ members in group 2) using a sequence of single photons. These single photons are used directly to encode classical information in a quantum secret sharing process. In this protocol, all members in group 1 directly encode their respective keys on the states of single photons via unitary operations; then, the last one (the $m\mathrm{th}$ member of group 1) sends $1∕n$ of the resulting qubits to each of group 2. Thus the secret message shared by all members of group 1 is shared by all members of group 2 in such a way that no subset of each group is efficient to read the secret message, but the entire set (not only group 1 but also group 2) is. We also show that it is unconditionally secure. This protocol is feasible with present-day techniques.

Securing Cloud Containers Using Quantum Networking Channels

Brian Kelley, John Jeffery Prevost, Paul Rad +1 more

While all cloud based platforms possess security vulnerabilities, the additional security challenges with container systems stem from the sharing of Host OS among independent containers. If a malicious application was to break into the root of container Daemon, it could gain root access into the host kernel thereby compromising the entire system. It could create Denial-Of-Service attack for other user applications, rejecting service to other applications. In this paper, we propose a quantum network security framework for the cloud. We devise a means by which quantum particles, denoted entangled bell pairs, are routed to network nodes. This enables teleportation of quantum information between source and destination only when root privileges are required by an application. The secure quantum channel works on a use-once only policy, so the key data cannot be easily copied, regenerated or spoofed without detection. A network framework for multiple pre-staged channels is devised and we illustrate that policy for network routing of entangle particles formulated as a multi-tenant teleportation network, capable of disseminating key data to servers hosting Docker container applications. The framework can achieve provably high levels of security and is capable of integration into a cloud data center for securing applications using Docker Containers. We also describe quantum network layer protocols for cloud container security that leverage the unique properties of quantum entanglement. To resolve security concerns, this layer would control access between application and container daemon, thereby facilitating restricted communication with proper authentication.

Quantum network based on multiparty quantum secret sharing

Hongyang Ma, Bingquan Chen

In this paper we develop a quantum network with a mutual quantum secure direct communication scheme based on multiparty quantum secret sharing. This quantum network, assuming to contain clusters S, M, and D, shares a sequence of single photons and Greenberger-Horne-Zeilinger (GHZ) states. Each cluster is made of the same or similar quantum nodes gathered or occurring closely together. The feature of this scheme is that the communication between two clusters depends on the agreement of the third cluster. We also prove that such a quantum network is unconditionally secure.

Spectral-temporal-polarization encoding of photons for multi-user secure quantum communication

Eric Donkor

We describe a Quantum Key Distribution protocol that combines temporal-, spectraland polarization-encoding of photons for secure communication over an interconnected network of users. Temporal encoding is used to identify a user’s location or address on the network. Polarization encoding is used to generate private cryptographic key. Polarization encoded information is locally and randomly generated by users and exchanged only over a dedicated secure channel. Spectral encoding allows for the detection of eavesdropping and tampering by a malicious agent. Temporal-spectral signals sent from the network administrator (Alice) to a user are bright light source. On the other hand spectral-temporal signal from a network user (Bob) to the administrator (Alice) are single photons. Signals are sent across the network as ordered light pairs. The ordering format is randomly chosen and are revealed only at the time of key selection between the parties so that a secure one-time cryptographic pad can be generated
