Abstract
A method is provided for generating an encrypted database. The method includes: receiving a plaintext database having plaintext data entries in one or more columns; augmenting the received plaintext database to generate an augmented plaintext database, the augmenting including the addition of one or more columns to the received plaintext database, each added column corresponding to an attribute which is to be made available for conditional queries; and encrypting the augmented plaintext database to generate the encrypted database including encrypted data entries. The encrypted database supports at least one form of conditional query for those attributes corresponding to the added columns, the at least one form of conditional query being computed on the encrypted data entries without the decryption thereof to produce an encrypted result.
