Then, we introduce a social-based privacy-preserving packet forwarding protocol, called SPRING, for vehicular DTNs. With SPRING, Roadside Units (RSUs) deployed along the roadside can assist in packet forwarding to achieve highly reliable transmissions. In specific, we first heuristically define how to evaluate each traffic intersection’s social degree in a vehicular DTN. Based on the social degree information, we then strategically place RSUs at some high-social intersections. As a result, these RSUs can provide tremendous assistance in temporarily storing packets and helping packet forwarding to achieve high delivery ratio. Performance evaluations via extensive simulations demonstrate the SPRING’s efficiency. In addition, detailed security analyses show that the proposed SPRING can achieve conditional privacy preservation and resist most attacks existing in vehicular DTNs. 此讲座为前沿课题讲座（可盖章），欢迎全校师生踊跃参加。校学术委员会计算机学院信息安全中心 2010年10月21日主讲人简介： Xiaodong Lin received the Ph.D. degree in information engineering from Beijing University of Posts and Telecommunications, China, in 1998 and the Ph.D. degree (with Outstanding Achievement in Graduate Studies Award) in electrical and computer engineering from the University of Waterloo, Canada, in 2008.
