Fault injection deals with the insertion or simulation of faults in order to test the robustness and fault tolerance of a software application [8]. Such measures are generally performed on software that is mission critical, to the extent that failure could have significant negative ramifications. Actual injection of faults can be performed either at compile time, when additional code is inserte...

Fault injection techniques are important and widely used for verifying the dependability of computer systems. Traditionally fault injection has been successfully applied for evaluating dependability of hardware electronics and is now increasingly been used for software systems. At the same time increasing complexity of embedded software systems such as in automotive sector has driven these doma...

This paper describes the usage of fault injection for testing a version of the μC/OS-II kernel which we extended with robust partitioning mechanisms. The implemented mechanisms were tested using a new fault injection plug-in for the GOOFI tool, which aims to provide robustness testing for partitioned systems. We describe the kernel extension and the experiments, with the goal of fault removal, ...

This paper introduces a new methodology for validation of dependable systems based on physical fault injection. The approach defines the elements of the injection environment and the requirements that are necessary to control the injection process with fine granularity, allowing for the elimination of glitches and not valid experiments and therefore making the validation process more accurate. ...

In this paper, a method of low power analog testing is proposed. In spite of having Oscillation Based Built in Self-Test methodology (OBIST), a look up table based (LUT) low power testing approach has been proposed to find out the faulty circuit and also to sort out the particular fault location in the circuit. In this paper an operational amplifier, which is the basic building block in the ana...

The paper deals with the problem of testing computer system’s susceptibility to hardware faults by means of software implemented fault injectors. Basing on our experience with fault injection techniques we present various strategies of fault stressing in relevance to fault impact analysis in the function of the application input data profile, fault injection profile in time and space, resource ...

With the increasing number of embedded computer systems being used in safety critical applications the testing and assessment of a system’s fault tolerance properties become a crucial issue. Experimental fault injection plays an important role in the process of fault tolerance assessment. The restricted accessibility of nodes within a chip or system-on-a-chip, however, make such experiments ext...

This paper describes and compares three physical fault injection techniques—heavy-ion radiation, pin-level injection, and electromagnetic interference—and their use in the validation of MARS, a fault-tolerant distributed real-time system. The main features of the injection techniques are first summarized, and then the MARS system is described. The distributed testbed setup and the common test s...

Advanced Encryption Standard (AES) cryptographic system are widely used in embedded systems to secure secret information. One of the most powerful cryptanalysis techniques against the cryptographic systems is the fault injection attacks. The complexity of cryptographic systems is increasing which requires fast security attacks simulation against fault injection attacks. The multi-level Electron...
