摘要
A client queries a set of encrypted data instances located at a server with a query attribute of the client. The set of encrypted data instances is associated with a set of ciphertexts, wherein a ciphertext is an encrypted function of a representation of a corresponding data instance and a data instance attribute extracted from the corresponding data instance. The client decrypts the ciphertext from the set of ciphertexts based on a distance function of the query attribute and the data instance attribute to produce the representation, and accesses the corresponding data instance using the representation.
