Abstract

This paper offers a stochastic model and a combined analysis of safety and security of the e-Motor, an ASIL D (ISO 26262) compliant device designed for use with AUTOSAR CAN bus.

The paper argues that in the absence of credible data on the likelihood and payload of cyber attacks on newly developed devices a sensible approach would be to separate the concerns: (i) the payloads that may affect the device’s safety can be identified using standard hazard analysis techniques; (ii) the difficulty with the parameterization of a stochastic model can be alleviated by applying sensitivity analysis for a plausible range of model parameter values.
