Software-Architecture Recovery from Machine Code
In this paper, we present a tool, called Lego, which recovers object-oriented software architecture from stripped binaries. Lego takes a stripped binary as input, and uses information obtained from dynamic analysis to (i) group the functions in the binary into classes, and (ii) identify inheritance and composition relationships between the inferred classes. The information obtained by Lego can be used for reengineering legacy software, and for understanding the architecture of software systems that lack documentation and source code. Our experiments show that the class hierarchies recovered by Lego have a high degree of agreement---measured in terms of precision and recall---with the hierarchy defined in the source code
Modernizing science&engineering software systems
As the demands for modernized legacy systems rise, so does the need for
frameworks for information integration and tool interoperability. The Object Management
Group (OMG) has adopted the Model Driven Architecture (MDA), which is an evolving
conceptual architecture that aligns with this demand. MDA could help solve coupling
problems of multidisciplinary character in science and engineering that consist of one or more
applications, supported by one or more platforms. The objective of this paper is to describe
rigorous techniques to control the evolution from science & engineering software legacy
systems to MDA technologies. We propose a rigorous framework to reverse engineering code
in the context of MDA. Considering that validation, verification and consistency are crucial
activities in the modernization of systems that are critical to safety, security and economic
profits, our approach emphasizes the integration of MDA with formal methods
Analysis of Software Binaries for Reengineering-Driven Product Line Architecture\^aAn Industrial Case Study
This paper describes a method for the recovering of software architectures
from a set of similar (but unrelated) software products in binary form. One
intention is to drive refactoring into software product lines and combine
architecture recovery with run time binary analysis and existing clustering
methods. Using our runtime binary analysis, we create graphs that capture the
dependencies between different software parts. These are clustered into smaller
component graphs, that group software parts with high interactions into larger
entities. The component graphs serve as a basis for further software product
line work. In this paper, we concentrate on the analysis part of the method and
the graph clustering. We apply the graph clustering method to a real
application in the context of automation / robot configuration software tools.Comment: In Proceedings FMSPLE 2015, arXiv:1504.0301
A Process-Oriented Software Architecture Reconstruction Taxonomy
International audienceTo maintain and understand large applications, it is cru- cial to know their architecture. The first problem is that architectures are not explicitly represented in the code as classes and packages are. The second problem is that suc- cessful applications evolve over time so their architecture inevitably drifts. Reconstructing and checking whether the architecture is still valid is thus an important aid. While there is a plethora of approaches and techniques supporting architecture reconstruction, there is no comprehensive state of the art and it is often difficult to compare the ap- proaches. This article presents a first state of the art in soft- ware architecture reconstruction, with the desire to support the understanding of the field
Science & engineering software migration: moving from desktop to mobile applications
The proliferation of mobile devices over the last years provides opportunities and challenges for solving problems in Science & Engineering. Among other novel features, mobile devices contain global positioning sensors, wireless connectivity, built-in web browsers and photo/video/voice capabilities that allow providing highly localized, context aware applications. Mobile phones have become as powerful as any desktop computer in terms of applications they can run. However, the software development in mobile computing is still not as mature as it is for desktop computer and the whole potential of mobile devices is wasted. A current problem in the engineering community is the adaptation of desktop applications for mobile technologies.
To take advantage of new platform technologies, existing software must evolve. A number of solutions have been proposed to deal with this problem such as redevelopment, which rewrites existing applications, or migration, which moves the existing system to a more flexible environment while retaining the original system data and functionality. A good solution should be to restore the value of the existing software, extracting knowledge and exploiting investment in order to migrate to new software that incorporates the new technologies.
On the one hand, traditional reverse engineering techniques can help in the software migration to mobile applications. They are related to the process of analyzing available software with the objective of extracting information and providing high-level views on the underlying code. On the other hand, to achieve interoperability with multiple platforms the migration needs of technical frameworks for information integration and tool interoperability such as the initiative of the Object Management Group (OMG) called Model Driven Architecture (MDA). The outstanding ideas behind MDA are separating the specification of the system functionality from its implementation on specific platforms and managing the software evolution from abstract models to implementations increasing the degree of automation.
The objective of this paper is to describe a reengineering process that allow moving existing desktop applications for solving engineering problems of multidisciplinary character to mobile platforms. Our research aims to simplify the creation of applications for mobile platforms by integrating traditional reverse engineering techniques, such static and dynamic analysis, with MDA. We validated our approach by using the open source application platform Eclipse, EMF (Eclipse Modeling Framework), EMP (Eclipse Modeling Project) and the Android platform
Reverse Engineering: Methodologies for Web Applications
The Reverse Engineering of Web Applications is a complex problem, due to the variety of languages and technologies that are contemporary used to realize them. Indeed, the benefits that can be obtained are remarkable: the presence of documentation at different abstraction levels will help the execution of maintenance interventions, migration and reengineering processes, reducing their costs and risks and improving their effectiveness. Moreover, the assessment of the maintainability factor of a Web Application is an important support to decision making processes. Business processes are often implemented by mean of software systems which expose them to the user as an externally accessible Web application. This paper describes a methodologies for recovering business processes by dynamic analysis of the Web applications which ex-pose them
