A Key Issuing Scheme in IBE-based Distributed Online Social Networks
Yangrong Chen, Guanglin Xing · Journal of Networks · 2013
This paper presents a novel key issuing scheme for distributed online social networks based on identity-based encryption (IBE). The scheme involves two essential objects, Key Privacy Authority (KPA) and Privacy Chum (PC). KPA and PC cannot impersonate network users to obtain users’ private keys. The experiment results indicate that the scheme is feasible and efficient, and it can sustain large-scale online social networks.
