Data integrity checking protocol based on secure multiparty computation

Abstract

In this paper, we defined a new cloud-oriented model for data integrity checking, in which there were three participants: a data owner, a data checker, and a cloud server, and the data checker could perform the checking procedure with the permission and the help of the data owner. Furthermore, we presented a two-party protocol for secure modular computation (SModC), and then proposed a data integrity checking protocol based on the SModC protocol. Due to its high efficiency and security, the proposed protocol has good application prospects, especially in the fields of cloud computation and big data.
