Trajectory privacy-preserving for Location-based Social Networks (LBSNs) has been received much attention to protect the sensitive location information of subscribers from leaking. Existing trajectory privacy-preserving schemes in literature are confronted with three problems: 1) it is limited for privacy-preserving by only considering the location anonymization in practical environment, and the sensitive...
Security protocols are hard to design, even under the assumption of perfect cryptography. This is especially true when a protocol involves different timing aspects such as timestamps, timeout, delays and a set of timing constraints. In this paper, we propose a methodology for modeling and analyzing security protocols that are aware of timing aspects. We develop a formalism for modeling security protocols...
