Based on current trends for both military and commercial applications, the use of mobile devices (e.g. smartphones and
tablets) is greatly increasing. Several military applications consist of secure peer to peer file sharing without a
centralized authority. For these military applications, if one or more of these mobile devices are lost or compromised,
sensitive files can be compromised by adversaries, since COTS devices and operating systems are used. Complete
system files cannot be stored on a device, since after compromising a device, an adversary can attack the data at rest, and
eventually obtain the original file. Also after a device is compromised, the existing peer to peer system devices must still
be able to access all system files.
McQ has teamed with the Cryptographic Engineering Research Group at George Mason University to develop a custom
distributed file sharing system to provide a complete solution to the data at rest problem for resource constrained
embedded systems and mobile devices. This innovative approach scales very well to a large number of network devices,
without a single point of failure. We have implemented the approach on representative mobile devices as well as
developed an extensive system simulator to benchmark expected system performance based on detailed modeling of the
network/radio characteristics, CONOPS, and secure distributed file system functionality. The simulator is highly
customizable for the purpose of determining expected system performance for other network topologies and CONOPS.
