A method for protecting location information in wireless communication networks, wherein the communication network includes an access point (AP), as well as nodes (N<SUB>i</SUB>) associated with the access point (AP), is - with regard to a secure transmission of packets over the wireless medium - characterized in that an individual broadcast link - channel (C<SUB>i</SUB>) - is generated between the access point (AP) and each of the nodes (N<SUB>i</SUB>), wherein the channels (C<SUB>i</SUB>) are each defined by a channel-specific key (K<SUB>i</SUB>), and wherein the headers or parts of the headers of packets to be sent between the access point (AP) and the nodes (N<SUB>i</SUB>) are encrypted with the corresponding key (K<SUB>i</SUB>) before their transmission. |
