Abstract
In a multi-hop network, packets are classified into header and user data for coded distribution. The header information, especially the multi-hop information, is separated in a coded manner from the user data, such that each network node need only decode the header in order to forward the packet. The header and the user data are guided, independently from each other, to the hardware of the respective device for separate coding, as if they were complete packets. A hardware accelerated coding of header and user data is possible using different keys. The header also contains integrity protection.

19. A method for transmitting data in a communication system using a multi-hop method, comprising:
-
providing a network, wherein the network has a node; providing a first node transmitting data; providing a second node receiving data; providing a third node for receiving data and forwarding data; transmitting data from the first node to the second node via the third node; fragmenting data into packets for transmission purposes, wherein the packets have a payload data component, a first control data component assigned to the multi-hop method, and a second control data component assigned to the network; and encrypting the data based upon at least a first master key determined by the first node and second node, wherein the payload data component and the first control data component are encrypted separately. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
