Abstract: Systems, methods, and apparatus to provide private information retrieval are disclosed. An example apparatus includes a protected data enclave to store a first portion of data such that entities other than the first trusted hardware processing unit are unable to access the first portion of the data. The example apparatus includes a request processor to determine that a data element specified in a first request from an entity is stored in a second trusted hardware processing unit. The request processor is to send an encrypted request for the data element to the second trusted hardware processing unit, and send an encrypted dummy request to a third trusted hardware processing unit. The request processor is to determine whether an encrypted dummy response has been received from the third trusted hardware processing unit, and whether an encrypted response including the data element has been received from the second trusted hardware processing unit.
