Recent real-world attacks against Certification Authorities (CAs) and fraudulently issued certificates arouse the public to rethink the security of public key infrastructure for web-based connections. To distribute the trust of CAs, notaries, as an independent party, are introduced to record certificates, and a client can request an audit proof of certificates from notaries directly. However, there...
Mobile data offloading is a feasible and cost-effective solution to ease the burden of cellular networks. In Internet of Vehicles, however, existing offloading techniques are hardly applicable to the ubiquitous location-dependent services, which impose strict spatiotemporal constraints on content delivery. Particularly, the spatiotemporal constraints cause a phenomenon where the delivery deadlines...
This paper presents the fabrication process and the properties of the CoNiMnP-based permanent magnetic film fabricated with electrodeposition technique. The CoNiMnP magnetic film was fabricated on silicon substrate using MEMS compatible micromachining process. The film consists of magnet array with 5mm×5mm square cells with the thickness of 12μm and 20μm. And some specific methods were used in the...
We consider pervasive computing environment where information is exchanged among nodes in a peer-to-peer fashion. We apply a hybrid approach and focus on the design of a bandwidth efficient overlay. Our approach, called together, is based on the observation that participating peers is more likely not to contribute available bandwidth for the delivery quality of others. To identify these peers, we...
