We investigate kernel mechanisms for enforcing system security policies. In particular, we investigate kernel mechanisms for eliminating timing side channels that are general and minimal enough to merit inclusion into a general-purpose production version of the kernel (i.e. one not only meant for deployments where timing channels are a concern). I am designing kernel mechanisms in seL4. seL4 is a capability based general-purpose microkernel. The design goal of seL4 is to provide a minimal set of mechanisms for high assurance systems, forming a good platform for system security research. Furthermore, we expect that our contributions will benefit not only seL4 but also other kernels or hypervisors.
