A sensor-cloud system is a combination of wireless sensor networks and cloud computing that is equipped with ubiquitous physical sensing ability, high-speed computation, huge storage, and so on. However, sensor-cloud systems suffer from various types of malicious attacks that can cause sensor communications to become unreliable. Establishing a trust evaluation method to ensure members’ reliability...
In cloud storage, the data owner and data users can easily perform cooperative work on shared data. In this paper, we focus on operation behavior auditing in shared cloud storage, which is significant for the avoidance of potential crimes in the cloud and equitable accountability determination for the forensic investigation in shared cloud. We first introduce a novel secure public auditing model for...
In cloud storage, auditing for operation behavior logs (OBLs) plays an increasingly important role in the field of cloud auditing. In this paper, we first introduce our third party auditing model for user's operation behavior. Further, a novel secure logging approach is proposed to ensure the OBLs security in cloud. Then, we present a secure public auditing scheme for OBLs. Specifically, BLS signature...
The development of mobile cloud computing technology has made location-based service (LBS) increasingly more popular. Given the continuous requests to cloud LBS servers, the amounts of location and trajectory information collected by LBS servers are continuously increasing. Privacy awareness for LBS has been extensively studied in recent years. Among the privacy concerns about LBS, trajectory privacy...
Recent years, with the emerging technology of cloud computing, the powerful computing and storage capability of cloud computing injects new vitality into wireless sensor networks (WSNs) and motivates a series of new applications. However, the data delivery from WSNs to Cloud becomes a bottleneck because of the poor communication ability of WSNs, especially for delay-sensitive applications, which limits...
