DataGuard: A Secure, Reliable and Efficient Data Storage and Transition System for Mobile Ad Hoc Network

We propose a secure, reliable and efficient data storage and transition system, DataGuard, for wireless ad hoc networks. As a distributed system, DataGuard integrates various coding techniques, data migration protocol and service evaluation model to enable secure data storage and efficient data access in wireless ad hoc networks. We adopt various coding techniques including erasure coding scheme, threshold crypto algorithm and symmetric crypto primitives to protect data at rest and in transit against eavesdropping and Byzantine attacks. Moreover, we propose to develop the data migration protocol that allows the data storage system to self-adapt to the network dynamics. Additionally, we propose to develop the service evaluation model that allows the data users to evaluate the data delivery service provided by the data storage nodes. The combination of coding schemes, the data migration protocol, and service evaluation model in DataGuard significantly improves the data availability with distributed implementation in wireless ad hoc networks. Finally, in the proposed effort, we will demonstrate the feasibility of the proposed coding techniques, data migration protocol and service evaluation model in a workable data storage and transmission prototype for wireless ad hoc networks.
