In the third project phase, there will be two major orientations: further developing hierarchical and autonomous network coding and physical-layer key generation and reconciliation for reciprocal wireless links.The goal of our network coding research is to finally propose modifications of existing routing protocols such as OSPF to support network coding. For determining the network coding sites, we will continue work on graph and agent based algorithms. We will now also include unequal error protection. Theinter-relation between Luby-Transform codes and network coding shall be considered in more detail and as a counterpart to physical-layer key generation, we will investigate Shamir's three-pass protocol, to use local operations to finally generate a unique key on both sides of a path secured fromeavesdropping.For correcting keys resulting from physical-layer generation, guard interval and code-supported methods will be further investigated and optimized. Additionally, Jamming on unused spatial dimensions will be added as a further security option, possibly allowing for a combination with PARreduction methods in multicarrier transmission.
