报告人:闫峥 教授，西安电子科技大学（Xidian University）
Pervasive Social Networking (PSN) offers instant social networking services at anytime and anywhere. It features in network adaptability, communication ubiquity and service intelligence. While security and privacy protection impact its development and final success, trust plays a decisive role in PSN. In this talk, we will discuss how to digitalize trust for securing PSN with privacy preservation by considering its specific characteristics and the role of trust in social communications. My talk is to present some of the research results of our project TruSoNet and will mainly focus on solving two research problems: the adaptability of social data access control and the anonymity of authentication. Concretely, we designed and implemented schemes for data protection and access control based on multi-dimensional trust levels and anonymous authentication on trust through certificateless authentication and aggregate signature verification for any number of authorized trust-issuing parties. Finally, the talk will be concluded with open research issues and future research directions.
