It remains challenging to retrofit the classic multithreaded programming model so that the security and privilege separation in multi-principal applications can be resolved. ...
An inherent security limitation with the classic multithreaded programming model is that all the threads share the same address space and, therefore, are implicitly assumed to be mutually trusted. ...
Conclusion Arbiter is a run-time system and a set of security primitives which can realize fine-grained and data-centric privilege separation for multi-principal multithreaded applications. ...
