Attacks on cryptosystem implementations (e.g. security fault injection, timing analysis and differential power analysis) are amongst the most exciting developments in cryptanalysis of the past decade. Altering the internal state of a cryptosystem or profiling the system’s computational dynamics can be used to gain a huge amount of information. This paper shows how fault injection and timing ana...

Piston scuffing is one of the destructive faults in internal combustion (IC) engines. There are different causes to make this fault that lack of lubricant is the most important one among them. The purpose of this paper is the quantitative study of the piston scuffing effects on the engine performance parameters which is a new research direction in the IC engine filed. For this reason, several e...

Internal Turn-Turn faults (TTF) are the most common failures in power transformers, which could seriously reduce their life expectancy. Although common protection schemes such as current-baseddifferential protection are able to detect some of the internal faults, some other minor ones (such as TTFs andshort circuit near the neutral point) cannot be detected by such schemes. Likewise, these rela...

Advanced Fault Diagnosis Techniques and Their Role in Preventing Cascading Blackouts. (December 2006) Nan Zhang, B.S., Tsinghua University, China; M.S., Tsinghua University, China Chair of Advisory Committee: Dr. Mladen Kezunovic This dissertation studied new transmission line fault diagnosis approaches using new technologies and proposed a scheme to apply those techniques in preventing and mit...

LEX is a stream cipher based on the round transformation of the AES block cipher, and it was selected for the final phase evaluation of the eSTREAM project. LEX is 2.5 times faster than AES both in software and in hardware. In this paper, we present a differential fault attack on LEX. The fault model assumes that the attacker is able to flip a random bit of the internal state of the cipher but ...

The ObjectAgent system is being developed to create a robust software architecture for autonomous control of complex systems. Agents are used to implement all of the software functionality and communicate through simplified natural language messages. These agents have a set of basic survival skills that monitor for internal software faults, providing low-level fault detection and recovery. High...

This paper proposes an integrated real time fault analysis tool for transmission line. The two primary techniques used in the fault analysis tool, uzzy adaptive resonance theory (ART) neural network and synchronized sampling, can offer accurate fault detection, classification, internal/external ault differentiation, and fault location. The paper makes several extensions of the two techniques so...

Power transformer is one of the most important equipments in the electric system. Dissolved Gases Analysis is an important method in the diagnosis of internal fault of transformers. Because the signs and types of fault have complicated nonlinear relations, the traditional methods cannot exactly meet the requirements of engineer application. This paper proposes synthesis of relational grey incid...

We present a formal veriication of the transient fault recovery aspects of the Reliable Computing Platform (RCP), a fault-tolerant computing system architecture for digital ight control applications. The RCP uses NMR-style redundancy to mask faults and internal majority voting to purge the eeects of transient faults. The system design has been formally speci-ed and veriied using the Ehdm veriic...
