Title: A New False Data Injection Attack on Smart Grid

Abstract:Smart grid is an emerging energy system, which has been heralded as a technological paradigm shift that can effectively address the issue of limited fossil fuel reserve in earth and also can reduce carbon emissions. However, modern cyber interconnected and computerized energy infrastructure has become the most targeted national critical infrastructure for cyberattacks. A recent high-profile cyberattack on the Ukraine power grid has compromised three power control centres, taking down 30 substations and leaving over 225,000 Ukrainians without power. Other high-profile attacks include penetrations over two US nuclear plants and the Struxnet attack over Iranian nuclear plant. Recently a new type of cyberattack called the false-data-injection attack has been discovered which can evade the widely deployed bad data detection method in the emerging smart grid (SG). Most existing works on false data injection attacks are based on the DC model while real-life industrial systems are actually AC model based. We have investigated the applicability of existing research works on the industrial scale system and discover a new false data injection attack that can penetrate industrial scale bad data detection mechanism.

Title: A Unified Multiuser Coding Framework for Multiple Access Technologies

Abstract: The core of the NOMA techniques is to combine modulation and coding to achieve a higher spectrum efficiency. In our work, multiple access techniques are viewed as generalized coding schemes to support both multiuser separation and coding gain. In this sense, traditional coding schemes, e.g., low-density parity-check (LDPC) code, can be viewed as a special case. Note that still a big difference exists between multiple access techniques and LDPC codes. In particular, both binary and non-binary LDPC codes are generated based on finite field theory; whereas multiple access works based on not necessarily a finite field. This work presents a mathematical framework, called "multiuser coding", to unify multiple access and traditional coding theories. To verify the proposed framework, we propose a uniquely decodable mapping (UDM) based codebook for futuristic multiple access communications. A three-dimensional Tanner graph based message passing algorithm (MPA) is introduced for multiuser detection. Simulation results show that the proposed scheme can support a large number of users with a promising performance.
