Abstract

The article presents a groundbreaking approach to secure multiparty computation through measurement-device-independent quantum secure multiparty summation. This method addresses the vulnerabilities of traditional quantum cryptographic protocols by eliminating the risk of side-channel attacks on measurement devices. The authors introduce two specific secure multiparty summations: secure multiparty modulo-2 summation (SMM2S) and secure multiparty modulo-d summation (SMMdS), along with their corresponding protocols. These protocols are designed to be feasible with current technology, using weak coherent pulses as quantum resources and simple single-particle operators and Bell-state identifications. The proposed methods are not only secure but also efficient, offering a promising solution for applications in quantum-secured blockchain, quantum federated learning, and other secure multiparty computations in the future quantum internet.
