Split Capabilities for Access Control

Karp, Alan H.; Gupta, Rajiv; Rozas, Guillermo; Banerji, Arindam


Keyword(s): access control; computer security; capability systems

Abstract: Split capabilities represent a new way to control access to resources that has advantages over traditional approaches in both scalability and revocation of privileges. We present the basic idea of split capabilities and describe how they were used in a commercial system. We also explain why a variety of common attacks against a system using split capabilities fail.
