Abstract:
In this paper we investigate security properties of the I/O Memory Management Units (IOMMUs) implemented in a multicore processor being a representative platform for future avionic systems. Freescale's P4080 is considered as such a candidate. On this platform we show an attack that can be performed by an (untrusted) driver accessing an interruptcapable Direct Memory Access (DMA) device. Our demonstrated attack bases on a weakness of the implemented IOMMU for Peripheral Component Intercon...     »
