Abstract
A reader device may receive a request including a permanent device identifier (PDI) for an ambient-power-enabled internet of things (AIoT) device. The reader device may generate an encrypted temporary device identifier (ETDI) based on application of an encryption algorithm to the PDI. Further, the reader device may obtain a short-ETDI based on application of a bitmask to the ETDI. Also, the reader device may transmit, over a radio interface, a trigger message including the short-ETDI to the AIoT device. Moreover, the reader device may receive, over the radio interface, a random access (RA) response message including the short-ETDI from the AIoT device. In an example, the request may be an inventory request, and the inventory request may be received from an AIoT function. Further, the request may include an indication that encryption is supported by the AIoT device.
