抜粋

Comparing two integers under the encrypted form is useful for privacy-preserving data mining, secure auction, and so on. Based on the ring-learning with errors (ring-LWE) assumption, Saha and Koshiba proposed a practical approach—SK17—in [NBiS2017], established under the 3-party computation model where two clients (one of them has a decryption key) compare their data via an outsource cloud server without revealing their data. In this study, we propose three enhanced schemes from SK17 to improve efficiency, security, and flexibility. We implement the first protocol to show its efficiency using the ring-LWE-based homomorphic encryption scheme proposed by Lauter et al., while providing security analysis and practicality evaluation in the theory for the other two protocols.
