Advanced Encryption Standard (AES) is the symmetric key standard for encryption and decryption. In this work, a 128-bit AES encryption and decryption using Rijndael Algorithm is designed and synthesized using verilog code. The fault detection scheme for their hardware implementation plays an important role in making the AES robust to the internal and malicious faults. In the proposed AES, a com...

Electro-hydraulic systems with regards to the their specific features and applications among other industrial systems including mechanical, electrical and pneumatic systems, have been widely taken into consideration by the scientists and researchers. Due to the fact that the electro-hydraulic system is inherently a nonlinear system, has some problems such as signals saturation, nonlinear effici...

The main focus of this paper is fault-tolerant control systems (FTCSs) for unmanned aerial vehicles (UAVs). The goals are to develop an Automatic-Flight Control System (AFCS)[8], based on fault detection and isolation (FDI) and a reconfiguration mechanism to accommodate them [7]. This paper describes a design approach of Model Predictive Control (MPC) with a linear internal model to achieve a l...

Waves reflected from and transmitted across fault zones can be used to extract information on those zones. Fault zones, characterized as either a low-velocity zone or fracture systems, modify the phase of the waveform and make the seismic response frequency dependent. In this paper we develop an extrapolation scheme for simulating fractures described as linear slip boundaries. Two 9 × 9 linear ...

This paper describes a new methodology to inject transient and permanent faults in digital systems. For this purpose, the simulation based fault injector VERIFY (VHDL-based Evaluation of Reliability by Injecting Faults efficientlY) has been developed, which allows fault injection at several abstraction levels of a digital system. The combined approach of injection and analysis of the results en...

Debugging programs is a complicated and cumbersome task. It is an iterative process which includes hypothesizing the cause of a failure and validating the hypothesis. Since programs comprise of many components with complex interactions this chain often involves several trials. Fault localization (FL) is the task of identifying components that are likely to cause the failure. Automated fault loc...

Fault tolerance is an essential part in the design of distributed computer systems [2]. Thus, testing algorithms for such systems often involves fault injection (FI) experiments to evaluate if the specified fault hypothesis holds for the implementation, i.e., faults can be seen as part of the valid input data of a fault-tolerant system. Basically, the different methods of FI can be grouped into...

This paper addresses the problem of fault collapsing in asynchronous circuits. We investigate different transistor-level implementations of some basic elements that are used in delay-insensitive asynchronous circuit designs, and analyze them in the presence of single stuckat faults. From this analysis, we conclude that all internal stuck-at faults which are detectable by Boolean testing, can be...
