This paper presents a novel protocol for secure multi-party computation (SMC) leveraging quantum networks and quantum key distribution (QKD). The core idea is to utilize the inherent security properties of QKD and quantum states to construct a secure computational environment, safeguarding the privacy of participants during distributed calculations. The protocol, termed Quantum Network-Based SMC (QN-SMC), employs a layered approach combining a classical pre-processing phase with a quantum computation phase secured by QKD. We detail the protocol's architecture, mathematical formulations, and security guarantees. The key contributions of this work lie in the integration of QKD into the SMC framework, enabling computation on distributed quantum states while maintaining confidentiality and integrity. We explore the feasibility and potential impact of this approach for applications requiring secure distributed processing within a quantum network. The protocol's performance is analyzed in terms of key distribution rates, computational overhead, and security levels.

Enhancing the security of the dual party computation is considered as primitive to establish a secured multiparty computation in the geographically distributed networks. With the advent of variously distributed paradigms like Cloud computing, IoT and Fog computing, securing ubiquitous computation that involves multiparty collaboration is considered an open research area that attains the attention of the researchers to develop novel protocols. Addressing the problem of secured computation over the network this paper presents a novel and hybrid quantum protocol in with Quantum key distribution is integrated with 3DES to enhance the secure computations through a quantum channel within the cloud infrastructure. Simulation results of the proposed protocol show that it outperforms many security protocols developed based on quantum resources.

The advent of distributed computing systems will offer great flexibility for application workloads, while also imposing more attention to security, where the future advent and adoption of quantum technology can introduce new security threats. For this reason, the Multi-access Edge Computing (MEC) working group at ETSI has recently started delving into security aspects, especially motivated by the upcoming reality of the MEC federation, which involves services made of application instances belonging to different systems (thus, different trust domains). On the other side, Quantum Key Distribution (QKD) can help strengthen the level of security by enabling the exchange of secure keys through an unconditionally secure protocol, e.g., to secure communication between REST clients and servers in distributed computing systems at the edge. In this paper, we propose a technical solution to achieve this goal, building on standard specifications, namely ETSI MEC and ETSI QKD, and discussing the gaps and limitations of current technology, which hamper full-fledged in-field deployment and mass adoption. Furthermore, we provide our look-ahead view on the future of secure distributed computing through the enticing option of federating edge computing domains.
