Xixiang Lv, received her B.Eng in 2001, and Ph.D. in 2007, both from Xidian University. She has been a professor at Xidian University since 2015. She has published 18 high-quality papers, including prestigious IEEE journals and conferences.  Her interests include information security, space information network security, and recently facial authentication, blockchain. 

Research Interests

1. Security in Space Information Network

Space information network consists of many satellites at different orbits, ground stations, and clients. The security problems in space information networks mainly come from four perspectives, namely secure handoff, secure transmission control, key management, and secure routing, which involve many special designs due to characteristics of space information network, like latency and high error bit rate. Solving these problems would enable space information networks to enhance detection and transmission capabilities compared to the current single Earth observation satellite.

2. Security Issues in Facial Authentication Systems

Facial authentication systems are user-friendly and fast, which make them more appealing than passwords. However, they suffer from some inherent vulnerabilities that may compromise their security. These vulnerabilities mainly come from attacks at points of facial systems. For instance, spoofing occurs at sensor where artifacts may be present to the camera. Working toward these issues would lead facial systems to more promising applications
