There is a need for research on the scientific base and engineering requirements for building trustworthy systems in dynamic environments. To address this need, we study risk analy...
In current commodity systems, applications have no way of limiting their trust in the underlying operating system (OS), leaving them at the complete mercy of an attacker who gains...
Secure, fault-tolerant distributed systems are difficult to build, to validate, and to operate. Conservative design for such systems dictates that their security and fault toleran...
