The default cache strategy of Content Centric Networking(CCN) is storing at each Content Router (CR) along the deliver path. It is high cache redundancy which causes the performance of CCN degradation. Hence, finding an efficient caching mechanisms is necessary in CCN. We agree that the single attribute can not to adapt to the complex network environment. the MAC considers hop count or distance, node...
In Location-Based Services (LBSs) mobile users submit location-related queries to the untrusted LBS server to get service. However, such queries increasingly induce privacy concerns from mobile users. To address this problem, we propose FGcloak, a novel fine-grained spatial cloaking scheme for privacy-aware mobile users in LBSs. Based on a novel use of modified Hilbert Curve in a particular area,...
Existing work on RFID authentication problems always make assumptions that 1) hash function can be fully used in designing RFID protocols; 2) channels between readers and the server are always secure. However, the first assumption is not suitable for EPC Class-1 Gen-2 tags, which has been challenged in many research work, while the second one cannot be adopted in mobile RFID applications where the...
