Abstract
A system and a method are disclosed for protecting the privacy of a wireless data transmission. A request is received from a client device to connect to a base station. A session identification is assigned to the client device and a set of transmission identifications are generated using a block cipher with the assigned session identification and a secret key as input. The transmission identifications identify a frequency channel and a time slot for the client device to wirelessly transmit a message to the base station. The set of transmission identifications are then encrypted and sent to the client device.
