  • Reverse Engineering Digital Forensics Rodrigo Lopes October 22, 2006
    Reverse Engineering Digital Forensics Rodrigo Lopes October 22, 2006 Introduction Engineering is many times described as making practical application of the knowledge of pure sciences in the solution of a problem or the application of scientific and mathematical principles to develop economical solutions to technical problems, creating products, facilities, and structures that are useful to people. What if the opposite occurs? There is some product that may be a solution to some problem but the inner workings of the solution or even the problem it addresses may be unknown. Reverse engineering is the process of analyzing and understanding a product which functioning and purpose are unknown. In Computer Science in particular, reverse engineering may be defined as the process of analyzing a system's code, documentation, and behavior to identify its current components and their dependencies to extract and create system abstractions and design information. The subject system is not altered; however, additional knowledge about the system is produced. The definition of Reverse Engineering is not peaceful though, especially when it concerns to court and lawsuits. The Reverse Engineering of products protected by copyrighting may be a crime, even if no code is copied. From the software companies’ point of view, Reverse Engineering is many times defined as “Analyzing a product or other output of a process in order to determine how to duplicate the know-how which has been used to create a product or process”. Scope and Goals In the Digital Forensics’ scope, reverse engineering can directly be applied to analyzing unknown and suspicious code in the system, to understand both its goal and inner functioning.

  • Software Security and Reverse Engineering
    Software Security and Reverse Engineering What is reverse engineering? Today the market of software is covered by an incredible number of protected applications, which don't allow you to use all features of programs if you aren't a registered user of these. Reverse engineering is simply the art of removing protection from programs also known as “cracking”. In Some other words cracking is described as follows: - “When you create a program you engineer it, in fact you build the executable from the source-code. The reverse engineering is simply the art of generate a source-code from an executable. Reverse engineering is used to understand how a program does an action, to bypass protection etc. Usually it's not necessary to disassemble all code of the application not only the part of the application that we are interested must be reversed. Reverse engineering used by a cracker to understand the protection scheme and to break it, so it's a very important thing in the whole world of the crack.” In short: - "Reverse Engineering referred to a way to modify a program such that it behaves as the way a reverse engineer wish." “Cracking is a method of making a software program function other than it was Originally intended by means of investigating the code, and, if necessary, patching It.” A Little bit of history Reveres egg. Most probably start with the DOS based computer games. The aim is that a player has full life and armed in the final stage of the game. So what a reverse egg.

  • Soft Robotic Hand Prosthesis Using Reverse Engineering and Fast Prototyping
    Proceedings of the 1 st Iberic Conference on Theoretical and Experimental Mechanics and Materials / 11 th National Congress on Experimental Mechanics. Porto/Portugal 4-7 November 2018. Ed. J.F. Silva Gomes. INEGI/FEUP (2018); ISBN: 978-989-20-8771-9; pp. 953-966. PAPER REF: 7452 SOFT ROBOTIC HAND PROSTHESIS USING REVERSE ENGINEERING AND FAST PROTOTYPING Hugo D’Almeida, Tiago Charters, Paulo Almeida, Mário J.G.C. Mendes (*) Instituto Superior de Engenharia de Lisboa (ISEL), Instituto Politécnico de Lisboa, Lisboa, Portugal (*) Email: [email protected] ABSTRACT The present work aimed to develop a soft robotic prosthesis of the human hand using reverse engineering and fast prototyping. This project arises in response to some limitations of the current conventional prostheses, namely aesthetic, mechanical and cost, that fail to fulfil the needs of its users, for example with soft objects. The hand prosthesis design involved the acquisition and processing of a medical image of the user's hand, followed by a modelling process which proved to be highly complex, and finally the obtainment of a real model (by 3D printing) of the prosthesis. The results obtained proved to be satisfactory in the approximation of the hand morphology, low cost and the designed mechanical properties. However, due to some technological limitations (the used 3D printers), and more specifically in the physical conception of the model, its functionality is yet to be proved with the pneumatic control. Keywords: Soft robotics, reverse engineering, fast prototyping, hand prosthesis. INTRODUCTION The human hand can be considered the most used tool by the man in the execution of the daily tasks, and its loss leads to physical and psychological damages.

  • Reverse Engineering Is Reverse Forward Engineering)
    RE- ENGINEERING The reengineering of software was described by Chikofsky and Cross in their 1990 paper, as "The examination and alteration of a system to reconstitute it in a new form" . Less formally, reengineering is the modification of a software system that takes place after it has been reverse engineered, generally to add new functionality, or to correct errors. This entire process is often erroneously referred to as reverse engineering; however, it is more accurate to say that reverse engineering is the initial examination of the system, and reengineering is the subsequent modification. Re-engineering is mostly used in the context where a legacy system is involved. Software systems are evolving on high rate because there more research to make the better so therefore software system in most cases, legacy software needs to operate on a new computing platform. 'Re-engineering' is a set of activities that are carried out to re-structure a legacy system to a new system with better functionalities and conform to the hardware and software quality constraint. FORWARD ENGINEERING Forward engineering is the opposite of reverse engineering. In forward engineering, one takes a set of primitives of interest, builds them into a working system, and then observes what the system can and cannot do. Forward engineering is the foundation of synthetic psychology (Braitenberg, 1984; Dawson, 2004; Pfeifer & Scheier, 1999). Braitenberg has argued that forward engineering is likely to produce simpler theories than reverse engineering because the latter tends to attribute behavioural complexities to the internal mechanisms of the agent. Braitenberg calls this the law of uphill analysis and downhill synthesis.

  • Reverse Engineering a Legacy Software in a Complex System: a Systems Engineering Approach
    Reverse engineering a legacy software in a complex system: A systems engineering approach Maximiliano Moraga Yang-Yang Zhao University College of Southeast Norway University College of Southeast Norway Kongsberg, Norway Kongsberg, Norway +47 94195982 +47 31009699 [email protected] [email protected] Copyright © 2018 by Maximiliano Moraga and Yang-Yang Zhao. Published and used by INCOSE with permission. Abstract. In a complex system, a legacy software as a component is determined by various factors beyond its own capability. Lack of knowledge that shaped software, which is often the case of a legacy software, can prohibit appropriate maintenance and development to comply with the system needs. To reverse engineering legacy software for a fit with the overall system of interest is a daunting task. Existing techniques of reverse engineering are mostly from a purely technical point of view and for the single discipline of software engineering. Thus, this paper aims for an approach to properly reverse engineer the reasoning behind the legacy software developments in a complex system. By jointly apply the CAFCR model and the reverse engineering, a roadmap is created to guide incremental developments of legacy software in a complex system, which benefits both the maintenance of existing implementation and realization of new functionalities for improved system performance. Introduction Software development has the growing importance for many business successes. One critical issue for an existing business is the maintenance and continuous development of its software. With increasing competition, existing businesses have a tremendous pressure on the fast pace upgrading which left no time for the software to be re-created and re-implemented.

  • Towards Efficient Instrumentation for Reverse-Engineering Object Oriented Software Through Static and Dynamic Analyses
    Towards Efficient Instrumentation for Reverse-Engineering Object Oriented Software through Static and Dynamic Analyses by Hossein Mehrfard A dissertation submitted to the Faculty of Graduate and Postdoctoral Affairs in partial fulfillment of the requirements for the degree of Doctor of Philosophy in The Ottawa-Carleton Institute for Electrical and Computer Engineering Carleton University Ottawa, Ontario © 2017 Hossein Mehrfard Abstract In software engineering, program analysis is usually classified according to static analysis (by analyzing source code) and dynamic analysis (by observing program executions). While static analysis provides inaccurate and imprecise results due to programming language's features (e.g., late binding), dynamic analysis produces more accurate and precise results at runtime at the expense of longer executions to collect traces. One prime mechanism to observe executions in dynamic analysis is to instrument either the code or the binary/byte code. Instrumentation overhead potentially poses a serious threat to the accuracy of the dynamic analysis, especially for time dependent software systems (e.g., real-time software), since it can cause those software systems to go out of synchronization. For instance, in a typical real-time software, the dynamic analysis result is correct if the instrumentation overhead, which is due to gathering dynamic information, does not add to the response time of real-time behaviour to the extent that deadlines may be missed. If a deadline is missed, the dynamic analysis result and the system’s output are not accurate. There are two ways to increase accuracy of a dynamic analysis: devising more efficient instrumentation and using a hybrid (static plus dynamic) analysis.

  • Reverse Engineering in Product Manufacturing: an Overview
    DAAAM INTERNATIONAL SCIENTIFIC BOOK 2013 pp. 665-678 CHAPTER 39 REVERSE ENGINEERING IN PRODUCT MANUFACTURING: AN OVERVIEW KUMAR A.; JAIN, P. K. & PATHAK, P. M. Abstract: Reverse engineering plays vital role in the branch of the mechanical design and manufacturing based industry. This technique has been widely recognized as an important technique in the product design cycle. In regular computerized manufacturing environment, the operation order usually starts from the product design and ends with machine operation to convert raw material into final product. It is often essential to reproduce a CAD model of existing part using any digitization techniques, when original drawings or documentation are not available and used for analysis and modifications are required to construct a improved product design. In reverse engineering approach the important steps involved, are characterizations of geometric models and related surface representations, segmentation and surface fitting of simple and free-form shapes, and creating accurate CAD models. The chapter presents review on reverse engineering methodology and its application areas related to product design development. The product re-design and research with reverse engineering will largely reduced the production period and costs in product manufacturing industries.
