Malware detection has become a hot research pot as the development of Internet of Things and edge computing have grown in popularity. Specifically, various malware exploits firmware vulnerabilities on hardware platform, resulting in significant financial losses for both IoT users and edge platform providers. In this paper, we propose CodeDiff, a fresh approach for malware vulnerability detection on IoT and edge computing platforms based on the binary file similarity detection. CodeDiff is an unsupervised learning method that employs both semantic and structural information for binary diffing and does not require label data. Through the SkipGram with Negative Sampling, we generate the word vocabulary for instruction data. The Graph AutoEncoder is then used to embed both the semantic and structure information into the representation matrix for the CFG. After this, we employ the Improved Graph AutoEncoder to fuse all the function structures, function characteristics and function features to the fusion matrix. Finally, we propose the specific matrix comparison to achieve the high accuracy similarity results in short amount of time. Furthermore, we test the prototype on binary datasets OpenSSL and Curl. The results reveal that CodeDiff gives high performance on the binary file similarity detection, which contributes to identify malware vulnerability and improves the security of Internet of Things platforms.

gridcomputing is an emerging computing paradigm that have a significant impact on the next generation information infrastructure. Computer networks and the grid should be integrated together for supporting high-performance applications and a QoS-based network service broker is the key to this integration. In this paper, we propose a new approach for describing QoS capabilities of network services and develop a QoS-based broker technology for selecting network services that meet QoS requirements of gridapplications. Our approach for network service description and selection is highly flexible and applicable to networking systems with various implementations. We also propose a system architecture for realizing the QoS-based network service broker within the service-oriented grid architecture.

DAPSYS (internationalconference on Distributed and Parallel Systems) is an international biannual conference series dedicated to all aspects of distributed and parallel computing. DAPSYS 2008, the 7th internationalconference on Distributed and Parallel Systems was held in September 2008in Hungary. Distributed and Parallel Systems: Desktop gridcomputing, based on DAPSYS 2008, presents original research, novel concepts and methods, and outstanding results. Contributors investigate parallel and distributed techniques, algorithms, models and applications; present innovative software tools, environments and middleware; focus on various aspects of gridcomputing; and introduce novel methods for development, deployment, testing and evaluation. This volume features a special focus on desktop gridcomputing as well. Designed for a professional audience composed of practitioners and researchers in industry,this book is also suitable for advanced-level students in computer science.

Task scheduling is very important for effcient execution of large-scale workflows in distributed computing environments. Static scheduling schemes achieve high performance when executing workflow in stable environments. However, the scheduling costs are very high for largescale workflow and they may perform poorly if the system performance is changed dynamically. Demand-driven scheduling schemes achieve high performance for independent tasks, but they may perform poorly for workflow. Dynamic rescheduling schemes have the advantages of these two types of schemes, because tasks are rescheduled using algorithms from static scheduling schemes when the performance is changed. Thus, better performance can be achieved in workflow applications, although the scheduling costs are increased if the system performance is frequently changed. Therefore, a new dynamic scheduling scheme is proposed to reduce the number of rescheduling tasks. The rescheduling trigger of this scheme is based on task terminations. Moreover, the scheme reduces the number of rescheduling tasks compared to a scheme using a simple task termination trigger by checking dependencies between tasks. Evaluation using an abstract simulation demonstrated that the number of rescheduling tasks was reduced to approximately 1/4 to 1/100 of that without, and with a 5% increase of the execution time.

In this paper, we present a architecture of grid, and propose some gridapplications in network. grid technology provides secure, fundamental methods for advanced distributed computing and data sharing over the Internet. The popularity of the Internet as well as the availability of powerful computers and high-speed network technologies as low-cost commodity components is changing the way we use computers today. These technology opportunities have led to the possibility of using distributed computers as a single, unified computing resource. The grid technology has been used in applications in many disciplines.

With the proliferation of gridcomputing, a large number of computational resources are available for solving complex scientific and engineering problems. Nevertheless, it is non-trivial to write, deploy, and test gridapplications over heterogeneous and distributed resources. Further complicating matters, programmers may need to manually manage variations in source code due to resource heterogeneity. This paper presents an implementation of an integrated grid development environment that leverages IBM's Eclipse IDE and our application development framework, Worqbench. It provides novel tools to develop and debug grid software. It regards resources as first-class objects in the IDE and allows tight integration between the test beds and the code development process. We discuss how the environment assists programmers in developing gridapplications.
