Water Service Disruption UPDATE - Remote Operations Through Feb. 19Updated: Tuesday February 18, 2025 2:55 PM

The water service disruption in Jersey City affecting the Stevens campus continues as the City of Hoboken works to resolve the situation. All classes will continue to be held remotely, and offices will operate remotely both today and tomorrow, Wednesday, February 19. A citywide boil water advisory is now in effect. While there may be intermittent water availability, campus water service remains unreliable. Restroom facilities remain closed except for portable facilities. Even if water appears to be available, residents should not use building restrooms or shower facilities until further notice. Please monitor your email for further updates.

Speaker: Xiaochan Xue, Ph.D. Candidate, Department of Electrical and Computer Engineering, Stevens Institute of Technology

ABSTRACT

Distributed wireless networks are transforming communication systems, enabling seamless connectivity across IoT, smart cities, and beyond. However, their decentralized nature and open communication medium expose them to security threats and privacy risks. Traditional cryptographic methods, while effective, often fall short in addressing challenges like resource and cost constraints. This talk explores how physical layer security (PLS) offers an innovative solution by leveraging the wireless channel's inherent properties to combat eavesdropping and signal modification attacks. We will highlight key PLS techniques we used and discuss their integration with traditional methods for a multi-layered defense.
