Live migration is not supported by current Intel® SGX implementations. So, software emulation is unavoidable to enable deployed hypervisors migrating live virtual machines running SGX enclaves in the cloud. However, copying the running state of an enclave ...

This paper presents a new approach to autotuning data-parallel programs. Autotuning is a search for optimal program settings, which maximize its performance. The novelty of the approach lies in the use of the model checking method to find the ...

The paper aims at combining two research areas that traditionally have been disjoint: 1) model checking as used in formal verification, and 2) auto-tuning as used in high-performance computing. Our auto-tuning is an important use case of the ...

ZGC is a modern, non-generational, region-based, mostly concurrent, parallel, mark-evacuate collector recently added to OpenJDK. It aims at having GC pauses that do not grow as the heap size increases, offering low latency even with large heap sizes. The ...

Abstract: With the advent of the 5G era, embedded SIM (eSIM) technology has been created to meet the needs of M2M technology. In earlier years, the GSMA provided a detailed description of the architecture and configuration protocol of the eSIM over-the-...

Embedded SIM enables SIM provisioning to be performed after end users taken their equipments, and the security of the remote SIM provisioning protocol is of great significance to the security of whole mobile networks. This paper conducts formal analysis ...

During this prevailing generation of the digital world, mobile users are multiplying globally by leaps and bounds. A mobile banking system is an electronic channel for Electronic Banking (E-Banking) all over the world. The utility of mobile ...

• Help CDSS designers to determine the most suitable rule-based technology for modelling knowledge from CGs.

The over-use of antibiotics in clinical domains is causing an alarming increase in bacterial resistance, thus endangering their effectiveness as regards the treatment of highly recurring severe infectious ...

In this paper we propose an approach combining discrete event simulation and model checking. Indeed, methods like model checking suffer from the state space explosion when the modeled system is complex. Consequently, we propose an approach that allows ...

A term Cyber-Physical System (CPS) refers to a mathematically described (specified) real-world process, that combines discrete changes of pre-defined control states (a cyber part) and changes of controllable continuous-time states (a physical part)...

In this paper we present an approach to transform Home Area Network (HAN) model, described in SDL (Specification and Description Language), into DTPromela (Discrete-Time Promela) model. The aim is to prepare the DTPromela model in order to verify and ...

This paper presents a method for the integration of data originating from sensors and actuators that follow different formalisms, although they semantically interlap. We tested our approach one three Web of Things standards published respectively by the ...

Smart contracts can automatically perform the contract terms according to the received information, and it is one of the most important research fields in digital society. The core of smart contracts is algorithm contract, that is, the parties reach an ...

With the increasing complexity of the problems and systems arising nowadays, the use of multi-level models is becoming more frequent in practice. However, there are still few reports in the literature concerning methods for analyzing such models without ...

The difficulty of finding resources race is well known. Such errors are hard to be detected, because they often happen irregularly and reproduce difficultly. Especially, the kind race conflicts exist among processes, threads, and interrupts. This paper ...

The Internet has made the world smaller while there is still a gap between the cyber world and our physical world. In the future cyber-physical system CPS, all objects in cyber world and physical world would be connected, and the concepts of cyber world ...

Efficient modelling and verification of models need an accurate representation of systems. Especially, PROMELA cannot represent time as quantitative properties. That means some properties depending on time cannot be checked with SPIN model-checker. ...

This paper describes the results of an experimental study on the use of model checkers to verify properties of UML activity diagrams. The motivation for the study derives from the desirability of checking properties of systems early in the development ...

Set of autonomous nodes attached together and to a base station, working in a particular system is called wireless sensor network. Due to its wireless and dynamic nature, wireless sensor networks (WSNs) are easily attacked in comparison to wired ...

Observational determinism is a property that ensures the confidentiality in concurrent programs. It conveys that public variables are independent of private variables during the execution of programs, and the scheduling policy of threads. ...
