Data Base Security mechanisms for Mobile Ad-Hoc Networks (MANETS)

One aspect of the GIG, namely, Mobile ad-hoc networks (MANETS) present significant issues. Often, intermittent connectivity and mobility changes the network topology in such a way that the routing of information to a destination is not guaranteed to follow the same path. This is particularly difficult for centralized resources including databases, which provide a common mechanism to store and share information. Also, many networks services, including security, rely on centralized servers. Wireless devices such as Personal Digital Assistants (PDAs) that are used in MANETS have very limited power. These wireless devices typically have reduced computational power in order to prolong battery life. Encryption solutions need to be secure enough to protect the information without requiring too much computational power. Trident Systems proposes to design a database security model based on our experience with the GeoWiReM protocol and CG cross-domain XML security technology. Additionally, we propose to leverage current and emerging technology, such as Binary XML, to reduce the amount of bandwidth required to send information over the network and reduce the amount of computation power required to process the information. Finally, we plan to model the performance of database security solutions over MANETS.
