CrowdShare: Secure mobile resource sharing

Mobile smart devices and services have become an integral part of our daily life. In this context there are many compelling scenarios for mobile device users to share resources. A popular example is tethering. However, sharing resources also raises privacy and security issues. In this paper, we present CrowdShare, a complete framework and its (Android) implementation for secure and private resource sharing among nearby devices. CrowdShare provides pseudonymity for users, accountability of resource usage, and the possibility of specifying access control in terms of social network relationships. Further, CrowdShare preserves secure connectivity between nearby devices even in the absence of the mobile infrastructure. We have implemented CrowdShare on Android devices and report good performance results
