Despite its undeniable attractiveness as the only data protection mechanism with formal privacy guarantees, the concept of differential privacy has been repeatedly criticized because of the deteriorating effects of currently available differential privacy mechanisms. Due to the strong assumptions regarding the knowledge of a potential data intruder, the amount of noise that needs to be added to...

Power transformers are key components for electrical energy transfer in a Power system. In order to protect the transformers from these faults different protective methods are adopted. Some of them are differential protection, over excitation Protection, etc. In this Paper Over Voltage protection is established for the protection of the transformer. Microcontroller is used for the Power Transfo...

Since sensor applications are implemented in embedded computer systems, cyber attacks that compromise regular computer systems via exploiting memory-related vulnerabilities present similar threats to sensor networks. However, the paper shows that memory fault attacks in sensors are not the same as in regular computers due to sensor’s hardware and software architecture. In contrast to worm attac...

Security-aware embedded devices which are likely to operate in hostile environments need protection against physical attacks. For the RSA public-key algorithm, protected versions of the Montgomery powering ladder have gained popularity as countermeasures for such attacks. In this paper, we present a general fault attack against RSA implementations which use the Montgomery powering ladder. In a ...

This paper presents the use of ANN as a pattern classifier for differential protection of power transformer, which makes the discrimination among normal, magnetizing inrush, over-excitation, external fault and internal fault currents. The Back Propagation Neural Network Algorithm and Genetic Algorithm are used to train the multi-layered feed forward neural network and simulated results are comp...

Owing to the large magnitude of inrush currents, functionality differential protection power transformer may be threatened in correct discrimination between and internal faults. This article enhances through a computationally efficient method that utilizes phase angle current signals transformers (CTs). The proposed criterion (PDC) tracks fundamental CTs. While during an fault, angles both CTs ...

Abstract With the high penetration of distributed generation and gradual increase in loop network structures, existing over‐current protection distribution networks is difficult to apply. The use current differential has become an ideal solution, performance commercialization 5G communication provides effective way solve problem channel transmission. Aiming at based on 5G, this paper adopted ad...
