Binary-Level Fault Injection (BLFI) for AUTOSAR-based Systems

Abstract

Safety is a prime requirement for the automotive industry. Increasing use of complex electrical and electronic systems in vehicles has brought many safety concerns to the industry, in terms of reliability and robustness of these systems. AUTOSAR is an automotive development standard which aims to manage the increasing complexity of E/E systems without affecting their robustness. AUTOSAR facilitates functional safety and promotes a component-based development of automotive software. ISO 26262 is a functional safety standard for road vehicles which provides requirements and processes for developing robust automotive systems. Fault injection and interface testing are robustness assessment methods recommended by ISO 26262. This thesis proposes a binary-level fault injection technique called BLFI, which performs robustness testing on AUTOSAR-based systems. The proposed technique is a wrapping based approach and it can perform black box testing. This technique is evaluated with a proof-of-concept implementation on an AUTOSAR-based LED blinker application.
