“…The research task of QMSC is to solve the problem of collaborative computing among multiple mutually distrusted players while ensuring the confidentiality of their privacy inputs. As the study develops in depth, researchers have further applied QSMC to establish secure schemes for various computing scenarios in distributed networks, such as anonymous voting [1,2], private comparison [3,4], and secure multiparty summation [5][6][7]. Within them, quantum secure multiparty summation (QSMS) is the most essential primitive in QSMC, which can be extended to other multiparty computations.…”

The research of quantum secure multiparty computation is a subject of great importance in modern cryptography. In this study, we construct a veriﬁable quantum protocol for dynamic secure multiparty summation based on the cyclic property of d-level MUBs. Our protocol can realize dynamic parameter update in the aspect of members and secret inputs, improving the practicality of the protocol. Moreover, a veriﬁcation mechanism for result checking by applying ElGamal homomorphic encryption is given, and further enables the detectability of cheating behaviors, making our protocol safer. The security analysis proves the proposed protocol not only can resist a range of typical attacks from outside and inside, but also is secure against dishonest revoked participant attack which has been neglected in previous dynamic quantum summation protocols. From a theoretical perspective, compared with existing summation protocols, the protocol provides better practicability, higher privacy protection, and higher efﬁciency.
