One of the challenges for smart card deployment is the security interoperability. A smart card resistant to an attack on a given platform should be able to guarantee the same behavior on another platform. But the current implementations do not comply with this requirement. In order to improve such standardization the authors propose a framework based on annotations with an external pre-processi...

Arrays of integers are often compressed in search engines. Though there are many ways to compress integers, we are interested in the popular byte-oriented integer compression techniques (e.g., VByte or Google’s VARINT-GB). Although not known for their speed, they are appealing due to their simplicity and engineering convenience. Amazon’s VARINT-G8IU is one of the fastest byte-oriented compressi...

This project is concerned with researching and implementing a multi-threaded Java Virtual Machine (JVM) that can execute threads concurrently in hardware on a Field Programmable Gate Array (FPGA). A FPGA is a hardware device that has many applications ranging from embedded systems such as Mobile Phones, Signal Processing in Electric Guitars, and PDAs to high performance computing. A standard CP...

The subject of the article is formulation and solution inverse problem optimal redundancy in system residual classes (RNS) based on use dynamic programming method. this makes it possible to improve reliability operation computer systems components (CSC) RNS. purpose increase functioning CSC, which are built basis RNS, without reducing speed calculations, as well calculate compare reliability, t...

This paper discusses an algorithm to model any given multiple stuck at fault as a single stuck at fault with the insertion of at most n+3 gates, where n is the multiplicity of the targeted fault. The application of this model in circuit optimization, fault diagnosis and testing of multiply testable faults is discussed with examples. Any arbitrary multiple fault in combinational and sequential c...

in this paper, the fuzzy system has been used for fault detection and diagnosis of a yeast fermentation bioreactor based on measurements corrupted by noise. in one case, parameters of membership functions are selected in a conventional manner. in another case, using certainty factors between normal and faulty conditions the optimal values of these parameters have been obtained through the genet...

Multiple fault diagnosis is a difficult problem for dynamic systems. Due to fault masking, compensation, and relative time of fault occurrence, multiple faults can manifest in many different ways as observable fault signature sequences. This decreases diagnosability of multiple faults, and therefore leads to a loss in effectiveness of the fault isolation step. We develop a qualitative, event-ba...

Protection of computer systems and networks against malicious attacks is particularly important in industrial networked control systems. A successful cyber-attack may cause significant economic losses or even destruction controlled processes. Therefore, it necessary to test the vulnerability process possible cyber-attacks. Three approaches employing Generative Adversarial Networks (GANs) genera...

Until 2009, Java Cards have been mainly threatened by Logical Attacks based on ill-formed applications. The publication of the Java Card 3.0 Connected Edition specifications and their mandatory on-card byte code verification may have then lead to the end of software-based attacks against such platforms. However, the introduction in the Java Card field of Fault Attacks, well-known from the crypt...

The multiple fault diagnosis problem is important, since the single fault assumption can lead to incorrect or failed diagnoses when multiple faults occur. It is challenging for continuous systems, because faults can mask or compensate each other’s effects, and the solution space grows exponentially with the number of possible faults. We present a qualitative approach to multiple fault isolation...
