Research interests

Ning's current research interests include security in networked and distributed systems, applied cryptography, data privacy, trust and digital right managements.

She leads the security research subgroup in IMG, the School of Computer Science at the University of Manchester. The group currently works on a range of security projects including smart card based multi-factor authentication, authentication strength linked fine-grained access control, context-aware and adaptive security provision in mobile ad hoc networks and Ubiquitous Computing, digital rights management, accountable anonymity, signature delegation and distributed trust management.

She has led the completion of the FIDES (Fair Integrated Data Exchange Services) project working on the design of cryptographic primitives, protocols and architectures to address security threats and vulnerabilities in Internet-based e-commerce activities/transactions.

She has also led the FAME-PERMIS and the ES-LoA (E-infrastructure Security: Levels of Assurance) projects developing a multi-factor authentication framework and authentication strength linked fine-grained access control extension for the Shibboleth infrastructure.

She is one of the investigators of the clinical e-Science project, CLEF-Services, supervising the design and development of the CLEF security architecture to support secure remote access to patient data. She is also the designer of the architecture and algorithms to support privacy-preserving record linkage for the Genetic Lab Pilot project hosted at the Manchester St Mary Hospital, and the security advisor for the PsyGrid project on building a security bridge linking Janet and the NHS (National Health Services) Network.

She has published extensively in the field of security.
