Abstract
Abstract A method of transmitting data to a plurality of receivers is provided wherein an identifier is assigned to each of the receivers that cannot be ascertained once assigned, a subset of receivers is selected to receive data, and an encrypted board identifier corresponding to each receiver of the subset is transmitted, wherein a receiver of the subset becomes enabled upon receipt of the encrypted board identifier and data is transmitted with an indication that the data is only for receivers that have been enabled.
