DYNAMIC POLICY ENFORCEMENT FOR SOFTWARE DEFINED RADIO

Our research analyzes security policy enforcement issues inherent to handheld Software Defined Radio (SDR) devices. We have developed an abstraction for Dynamic Policy Enforcement (DPE) for a SDR system which consists of three distinct modules that monitor changes in external conditions, validate system configuration based on those conditions and a given policy, and implement changes to ensure policy compliance. In order to demonstrate the viability of our system, we created a prototype that implements the roles and responsibilities of our abstraction in conjunction with a prototype SDR system previously developed by NCSA that is based on the GNU SDR software.
