MiniBox: a two-way sandbox for ×86 native code

This paper presents MiniBox, the first two-way sandbox for x86 native code, that not only protects a benign OS from a misbehaving application, but also protects an application from a malicious OS. MiniBox can be applied in Platform-as-a-Service cloud computing to provide two-way protection between a customer's application and the cloud platform OS. We implement a Mini-Box prototype running on recent x86 multi-core systems from Intel or AMD, and we port several applications to MiniBox. Evaluation results show that MiniBox is efficient and practical.
