Abstract
Systems, devices, and methods are provided for secure multiparty computation (MPC) protocols. A first computing entity may send a first cryptographically protected data set to a server and a second computing entity may send a second cryptographically protected data set to the server. The server may lack access to plaintext versions of the data sets. The server may compare cryptographically protected data elements from the first and second data sets as part of a secure MPC protocol to determine certain information regarding the data sets, such as determining which data elements are included in both sets, and perform homomorphic computations according to a homomorphic encryption scheme. The server is accordingly able to determine an encrypted result.
