Secure Big Data Management based on Secret Sharing and Verifiable Computing
Momoko Shiraishi · 2021
Of late, more and more sensitive data have been connected with cyberspace, which has led to an increase in the importance of secure cloud computing. This paper shows an overall scheme of securely managing big data in a cloud supported by two technological methods, secret sharing and verifiable computing. While each of them was implemented and analyzed individually in previous works, this paper shows a comprehensive framework combining them to realize both security and efficiency in cloud data management. Specifically, secret sharing enables hiding the outsourced encrypted data from any unauthorized entity, and verifiable computing enable resource-constraint users to access the database in which the correctness is undoubtedly confirmed. This paper also compares the database scheme based on blockchain and the proposed method in terms of performance. The analysis shows that the proposed scheme entirely based on the conventional Internet computes the operations lighter than the blockchain scheme.
