Binary-level fault injection for autosar systems
Paper i proceeding, 2014
Continuously growing complexity of the automotive Electrical and/or Electronic (E/E) systems has prompted major manufacturers (OEMs) and suppliers to embrace the AUTOSAR (Automotive Open System Architecture) standard. Furthermore, recent introduction of ISO 26262, a functional safety standard for road vehicles, has confronted the automotive industry with rigorous requirements. This has become even more challenging as AUTOSAR highly promotes COTS (Commercial Off-The-Shelf) software for which access to source code is either restricted or non-existent. This paper contributes with a method and prototype tool for binary-level fault injection (BLFI) for AUTOSAR-based systems. The proposed BLFI tool can assist in achieving functional safety by evaluating robustness of software at any AUTOSAR layer even though only binaries are available. The proposed technique is quite generic and is evaluated with a proof-of-concept implementation of an AUTOSAR-based application.
