Abstract
Provided are methods and systems for performing secure analytics using term generations and a homomorphic encryption. An example method includes receiving, by at least one server from a client, a term generation function, a hash function, a public key of a homomorphic encryption scheme, and a homomorphically encrypted list of indices, wherein the list of indices is generated using the term generation function and the hash function, applying, by the server, the term generation function, the hash function, and the public key to a data set to determine a further homomorphically encrypted list of indices, extracting, by the server and using the homomorphically encrypted list of indices and the further homomorphically encrypted list of indices, data from the encrypted data set to obtain an encrypted result, and sending the encrypted result to the client to decrypt the encrypted result using a private key of the homomorphic encryption scheme.
