One of the key issues that should be considered when addressing reliable evolution is to place a software system in a consistent status before and after change. This issue becomes more critical at runtime because it may lead to the failure on running mission-critical systems. In order to place the affected elements in a safe state before dynamic changes take place, the notion of tranquility has been proposed to make quiescence criterion less disruptive and easier to obtain. However, it only ensures consistency in applications with restrictive black-box design. In this paper, an architecture-based approach is proposed to preserve global consistency during runtime reconfiguration of component-based systems in distributed contexts. An initial evaluation through a prototypical implementation shows that this approach not only enables tranquility to be applicable for distributed transactions, but also significantly reduces required time to achieve a safe state and increases system availability during runtime evolution.

User interface development and maintenance presents a burden for many developers. UI development approaches often restate information already captured in the application model such as entity attributes, validation, security, etc. Changes in application model often require many subsequent changes to the UI. Such duplication creates additional maintenance requirements for synchronization (at a minimum) and often is a source for errors (i.e., when model and UI disagree). Adding to the difficulties of creation and maintenance, typical UI implementations often tangle multiple concerns together such as presentation, validation, layout, security, etc. In this paper, we provide an approach that reduces information duplication and untangles mixed concerns. The capability of runtime UI generation can render user-specific UI, reduce conditional evaluation, and integrate third party security frameworks. To evaluate our approach, we provide a case study that demonstrates reduction of maintenance efforts, separation of concerns and performance of runtime UI generation. © 2012 IEEE.

This work introduces a novel, automated methodology for performing functional analysis of integrated circuits (ICs), such as microcontrollers and smart cards. By selectively executing code on a given chip, the resulting optical emission images yield critical information about the chip's functional layout. Automation of the code-generation allows us to generate and process hundreds of test cases that access specific elements of the IC. Subsequently, by correlating the executed code with the images, we are able to locate and identify functional elements of the chip's design, such as memory layout and important registers. This methodology provides an efficient way to isolate potential points of interest and thus significantly reduces the amount of effort required to mount attacks. We present exemplary results for a common microcontroller. © 2012 IEEE.

Architecture for Large-Scale Innovation Experiment Systems

Working IEEE/IFIP Conference on software Architecture

作者： Ulrik Eklund Jan Bosch Software Engineering Division Dept. of Computer Science & Engineering Chalmers University of Technology Göteborg Sweden

Business and design decisions regarding software development should be based on data, not opinions among developers, domain experts or managers. The company running the most and fastest experiments among the customer base against the lowest cost per experiment outcompetes others by having the data to engineer products with outstanding qualities such as power consumption and user experience. Innovation experiment systems for mass-produced devices with embedded software is an evolution of current R&D practices, going from where innovations are internally evaluated by the original equipment manufacturer to where they are tried by real users in a scale relevant to the full customer base. The turnaround time from developing and deploying an embedded product to getting customer feedback is decreased to weeks, the limit being the speed of the software development teams. The paper presents an embedded architecture for realising such a novel innovation experiment system based on a set of scenarios of what to evaluate in the experiments. A case is presented implementing an architecture in a prototype in-vehicle infotainment system where comparative testing between two software alternatives was performed.

One of the applications that motivates this research is a system for detection of the anomalies in wireless sensor networks (WSNs). Individual sensor measurements are converted to ellipsoidal summaries;a data matrix D is built using a dissimilarity measure between pairs of ellipsoids;clusters of ellipsoids are suggested by dark blocks along the diagonal of an iVAT (improved Visual Assessment of Tendency) image of D;and finally, the single linkage algorithm extracts clusters from D, using the iVAT image as a guide to the selection of an optimal partition. We illustrate this model for higher dimensional data with synthetic, real and benchmark data sets. Our examples show that two of the four measures, viz, Focal distance and Bhattacharyya distance, provide very similar and reliable bases for estimating cluster structures in sets of higher dimensional ellipsoids, that single linkage can successfully extract the indicated clusters, and that our model can find both first and second order anomalies in WSN data.

作者： Christopher Harrison Devin Cook Robert McGraw John A. Hamilton Jr. Dept. Computer Science & Software Engineering Auburn University Ram Laboratories Inc. San Diego Ca

Cloud computing has emerged in recent years as a major segment of the IT industry; however, security concerns remain the primary impediment to full-scale adoption. Leveraging properties of virtualization, virtual machine introspection (VMI) has yielded promising research for cloud security yet adoption of these approaches in production environments remains minimal due to a semantic gap: the extraction of high-level knowledge of the guest operating system's state from low-level artifacts collected out-of-VM. Within the field of forensic memory analysis (FMA), a similar semantic gap exists from the reconstruction of physical memory dumps. We implement a production oriented prototype utilizing designs that combines and narrows these semantic gaps in a modular framework to function as an intrusion detection system (IDS) detecting and defeating post-exploitation activity.

The explosive growth of image data leads to severe challenges to the traditional image retrieval methods. In order to manage massive images more accurate and efficient, this paper firstly proposes a scalable architecture for image retrieval based on a uniform data model and makes this function a sub-engine of AUDR, an advanced unstructured data management system, which can simultaneously manage several kinds of unstructured data including image, video, audio and text. The paper then proposes a new image retrieval algorithm, which incorporates rich visual features and two text models for multi-modal retrieval. Experiments on both ImageNet dataset and ImageCLEF medical dataset show that our proposed architecture and the new retrieval algorithm are appropriate for efficient management of massive image.

The literature abounds with discussions on the relative security merits of various voting systems, and on whether a move towards electronic voting is, from a security perspective, something to be encouraged or discouraged. Little has been said, however, on whether there would be unintended side-effects of changing the voting technology, in terms of the votes cast. Security issues aside, should we expect the introduction of an electronic voting system to affect the results of the election? This paper attempts to tease out some of the possible effects, by analysing ballot data from the 2008 Australian Capital Territory (ACT) Legislative Assembly Election. © 2012 Springer-Verlag.

International Conference on software and System Process (ICSSP)

There are many factors that provide input into the software development process, such as the values, beliefs, norms, practices, skills, behaviors, knowledge and goals of stakeholders. Research has shown that successful software system development relies on alignment or congruence between these factors. How to monitor the level of congruence between these factors and how to use the congruence as an indicator or a measure to monitor a software development process is a challenge in software engineering. This paper proposes a model that uses three congruence measures to examine the levels of social-technical congruence in software development processes. Using a controlled experiment with seven student teams developing a robot project, this paper demonstrates that the proposed congruence measures provide results consistent with the assessment by the course lecturers.
