Control Flow Aware Software-Implemented Fault Injection for Embedded CPUs

Fault injection is a highly used technique to test fault-tolerant embedded systems. We present a new software-implemented fault injection process to deterministically inject control flow errors in embedded CPUs. The proposed process analyses the disassembly file of the program acting on the embedded CPUs to construct the correct control flow. Once known, this information is used to deterministically inject intra-block, inter-block and out-of-function errors. To conclude, we discuss how our process can aid in performing a vulnerability analysis for a target algorithm.
