SECURE SEARCH SERVICE

An encrypted search query may be received from a requesting client system at a secure enclave of a processing device. The encrypted search query may be decrypted to form a decrypted search query. One or more index entries of a metadata index that correspond to the decrypted search query may be identified, such that each identified index entry is associated with a content reference that identifies a content item located outside the secure enclave. The index entries that correspond to the decrypted search query may include one or more index entries having one or more associated index metadata items that correspond to the decrypted search query. One or more secure search results may be generated, such that each secure search result corresponds to one of the index entries and comprises the content reference associated with the corresponding index entry. The secure search results may be sent to the requesting client system.
