Abstract
A system and a method select an encrypted element in an encrypted vector according to an order of the encrypted element in the encrypted vector. The selecting is performed in a privacy-preserving manner. Values of the elements of the encrypted vector are scaled, such that the order of the elements in the encrypted vector is preserved, and then permuted to produce a scaled permuted vector. Information in the encrypted domain indicative of an order of elements in the scaled permuted vector is provided to a second processor having a private key. The second processor decrypts the information to determine the index of the encrypted element based on the order of the elements. The encrypted element is obliviously selected based on the index.
