Ensuring a Resilient and Secure EV Charging Infrastructure for Sustainable Transportation
1. Ensuring a Resilient and Secure EV Charging Infrastructure for Sustainable Transportation （7月10日9：00-11：00，杨咏曼楼717）
摘要：To support the exponential rise in Electric Vehicle (EV) numbers, EV Charging Stations (EVCSs) are being deployed rapidly by operators and manufacturers alike. As a result, EVCSs have become an indispensable element of the transportation system. This highlights the need for a reliable and secure ecosystem to support the charging needs of EVs and achieve a sustainable transportation sector. Our research group studies the EVCS ecosystem security through examining its different components. The importance of the security of this ecosystem originates from the crucial service it provides and its connection to critical infrastructure such as the power grid. Our work focuses on uncovering the vulnerabilities of the EV ecosystem that can allow attackers to destabilize the power grid as well as developing to secure this ecosystem and Machine/Deep Learning intrusion/attack detection.
2. Non-Orthogonal Multiple Access for Massive Connectivity in Future Cellular Networks（7月10日13：00-15：00，杨咏曼楼717）
摘要：Non-Orthogonal Multiple Access (NOMA) has shown to enhance the spectral efficiency and network connectivity and thus is identified as a key enabling technology for the next-generation wireless network, sixth-generation (6G). The main concept of NOMA is to allow multiple users equipment (UEs) to share the same resource (code/frequency/time). In this talk, we focus on the synergistic integration between NOMA and other enabling fifth-generation and beyond (B5G) technologies looking for further improvement in the system performance in terms of spectral efficiency and network connectivity, including cooperative communication, reconfigurable intelligent surface, coordinated multi-point, etc. We will also present a non-orthogonal access scheme that exploits the partial overlap (i.e., similarity) among users bit sequences, and show that a much better enhancement to the spectral efficiency can be achieved, yielding gains of up to three times that of orthogonal access. The approach does not require complex SIC at the receiver side, and no power allocation is needed at the sender.
