Yanyan is currently researching how to improve the trustworthiness of commodity hardware through software to enable the verified microkernel to be used in situations previously needing an air gap. Multi-core processors are used to provide redundancy and cross-core checking is employed to detect divergence caused by hardware faults. The aim is to increase the trustworthiness of a virtual air gap created by the microkernel, and thus systems running on COTS hardware.
