Forming Virtualized Secure Framework for Location Based Services (LBS) using Direct Anonymous Attestation (DAA) protocol

The tremendous growth in mobile and wireless communications comes with more pervasive applications. Current mobile device platform does not allow a local or remote user to attest the target platform. The limitation of using existing software-based protection alone can be easily affected by malicious codes and it cannot assure its own integrity. In this paper, we explore a new approach of anonymity issues in Privacy Enhancing Technologies (PETs) which will result in the privacy enhancement of user personal data and location information in mobile network services. We create the foundation for running trusted applications, network and services on top of existing Mobile Location Protocol (MLP). We also propose a Virtualized Secure Framework between mobile devices (clients) and Location Based Services (LBS) Server in Virtual Machine (VM) environment based on Direct Anonymous Attestation protocol. Trusted Platform Module (TPM) acts as the foundation for mobile security mechanisms and privacy of user´s information. Virtualization is needed to improve the utilization of existing computing resources and to reduce hardware. Every single device found in a physical machine will be virtualized in the VMs. DAA protocol is proposed to anonymously verify the authority of users and preserve privacy of user´s private location information.
