Network Coding and Wireless Physical-layer Secret-key Generation From Unequal Erasure Protection (UEP) to Unequal Security Protection (USP)
- The general abstraction of this thesis is the relationships between two seemingly unrelated topics, which are network coding and wireless physical-layer secret-key generation (WPSG). As build-ups to such relationships, some specific aspects of each topic are discussed in detail at first. To begin with, network coding issues of unequal erasure protection (UEP) and degree distribution distortion of LT-coded symbols are presented. After that, the analysis regarding key length and security enhancement in WPSG is given. Towards the end, relationships between network coding and WPSG are revealed in two aspects, which are security protocols using network coding and scalable security based on the weakly secure network coding concept.
