Abstract With increasing application of cloud computing and big data technologies, a large amount of personal information is stored on the Internet, which raises the issue of privacy leakage.To protect people's data privacy, this paper firstly presents a new anonymous Identify-Based Encryption (IBE) scheme and gives the proof of its security under the Bilinear Diffie-Hellman Security Assumption. Then, by introducing the anonymous IBE scheme into anonymous communication fields, this paper introduces a new lightweight anonymous communication model for cloud computing, which guarantees the anonymity of system users and the security of messages in small groups. Our analysis shows that, the proposed communication model cannot only reduce memory consumption and improve message transmission efficiency, but also effectively resist traffic-analysis attacks, node eavesdropping, and finally achieve secure anonymous communication in cloud computing.

Scientific computing requires a huge amount of computing resources, but not all the scientific researchers have an access to sufficient high-end computing systems. Currently, Amazon provides a free tier account for cloud computing which could be used to build a virtual cluster. In order to investigate whether it is suitable for scientific computing, we first describe how to build a free virtual cluster using StarCluster on Amazon Elastic Compute Cloud (EC2). Then, we perform a comprehensive performance evaluation of the virtual cluster built before. The results show that a free virtual cluster is easily built on Amazon EC2 and it is suitable for the basic scientific computing. It is especially valuable for scientific researchers, who do not have any HPC or cluster, to develop and test their prototype system of scientific computing without paying anything, and move it to a higher performance virtual cluster when necessary by choosing more powerful instance on Amazon EC2.

Cloud computing is presently being paid much attention as a way of distribution and sharing out of information. Similarly, as latest experience illustrates, the unspecified, open environment of this technology presents more or less an idealistic environment for the augmented unauthentic communication. The issue of having trust in cloud computing is a main apprehension for the majority of computing industry. Presently, the important contents for research in cloud computing is to evaluate the trust and behavior based computing. The uncertainty of cloud nodes, the services and resources cloud provide may have a negative effect on the execution of cloud tasks. This makes it very difficult for the cloud node to interact effectively and increase the chances of transaction failures. The authors proposed a model, and design an algorithm of trust which is based on the social model of reputation and trust. The algorithm calculates the trust degree of a node before any communication take place between the nodes. This reduces the chances of failure and increase communication efficiency.

Intisari— Permasalahan pada penelitian ini adalah mengenai pengujian virtual machine di tingkat fungsionalitas aplikasi pada lingkungan komputasi awan di antara dua cloud provider IaaS (Infrastructure as a Service). Tujuan dari pengujian fungsionalitas ini adalah untuk mengetahui tingkat interoperabilitas aplikasi dalam sistem virtual machine yang berpindah dari sebuah cloud provider ke cloud provider lain, yaitu migrasi dari Amazon EC2 ke VMWARE. Peneliti memiliki ketertarikan mengenai pengujian migrasi ini sebab perkembangan Internet menjadi semakin pesat, dan diiringi dengan meningkatnya jumlah aplikasi yang memanfaatkan teknologi komputasi awan itu, sementara kemampuan proses bisnis suatu aplikasi semakin bertambah, fitur layanan yang ditawarkan para pihak cloud provider menjadi semakin baik (dari sisi harga menjadi lebih murah, performansi sistem menjadi lebih tinggi, sistem menjadi lebih handal, pemanfaatan kecanggihan teknologi security terbaru, maupun Service Level Agreement (SLA) menjadi lebih baik), maka memungkinkan untuk berpindah layanan ke cloud provider lain, namun di sisi praktik sering terjadi kegagalan fungsionalitas aplikasi dalam proses migrasi ke sistem cloud yang lain, yang antara lain disebabkan oleh masalah ketergantungan terhadap penyedia layanan komputasi awan (vendor lock-in). Masalah ketergantungan ini muncul disebabkan oleh jumlah cloud provider semakin bertanbah banyak dan mempunyai standar tersendiri dalam pembangunan sistemnya, sehingga dapat mengakibatkan kemampuan migrasi antar cloud itu dapat memiliki keterbatasan untuk hal-hal tertentu. Dengan 28 test case pengujian atas fitur-fitur pada aplikasi website ujian online yang diuji pada penelitian ini, diperoleh hasil tingkat interoperabilitas migrasi dari Amazon EC2 ke VMWARE memiliki nilai sebesar 46.43%. Kata kunci— pengujian, fungsionalitas, komputasi, awan, migrasi, interoperabilitas.

The Java programming language provides a comprehensive set of multithreading programming techniques but currently lacks interprocess communication (IPC) facilities, other than slow socket-based communication mechanisms (which are intended primarily for distributed systems, not interprocess communication on a multicore or multiprocessor system). This is problematic due to the ubiquity of modern multicore processors, and the widespread use of Java as a programming language throughout the software development industry. This work aimed to address this problem by utilising Microsoft Windows’ native IPC mechanisms through a framework known as the Java Native Interface. This enabled the use of native C code that invoked the IPC mechanisms provided by Windows, which allowed successful synchronous communication between separate Java processes. The results obtained illustrate the performance dichotomy between socket-based communication and native IPC facilities, with Windows’ facilities providing significantly faster communication. Ultimately, these results show that there are far more effective communication structures available. In addition, this work presents generic considerations that may aid in the eventual design of a generic, platform-independent IPC system for the Java programming language. The fundamental considerations include shared memory with semaphore synchronisation, named pipes and a socket communication model.
