Zusammenfassung:	A method for transmitting message frames, comprising: generating, by an end device comprising a processor, a first message frame portion comprising a first plain header; obtaining a device identifier (DevEUI) and a header blinding key (HdrBKey); generating a first header mask using the DevEUI and the HdrBKey; obtaining a first blinded header by applying the first header mask to the first plain header; obtaining a first updated message frame portion by updating the first message portion using the first blinded header; generating a first blinded message frame comprising the first updated message frame portion; and transmitting the first blinded message frame to a network gateway.
