Redesigning the Open Mobile Alliance License Choice Algorithm
  We claim that the Open Mobile Alliance (OMA) License Choice Algorithm, implemented in mobile DRM agents as specified by OMA suffers from a bug. More precisely there exist some cases that the user, may end up losing some rights without even to exercise them. We redesign this algorithm and claim that our approach eliminates this bug.
