International Journal of Computer Sciences and Engineering Open Access Research Paper Vol.-7, Issue-3, March 2019 E-ISSN: 2347-2693 A Decryption Process for Android Database Forensics Nibedita Chakraborty1*, Krishna Punwar2 1,2Dept. of Information Technology and Telecommunication, Raksha Shakti University, Ahmedabad, India *Corresponding Author: [email protected], Tel.: 7980118774 DOI: https://doi.org/10.26438/ijcse/v7i3.2326 | Available online at: www.ijcseonline.org Accepted: 18/Mar/2019, Published: 31/Mar/2019 Abstract— Nowadays, Databases are mostly usable in business applications and financial transactions in Banks. Most of the database servers stores confidential and sensitive information of a mobile device. Database forensics is the part of digital forensics especially for the investigation of different databases and the sensitive information stored on a database. Mobile databases are totally different from the major database and are very platform independent as well. Even if they are not attached to the central database, they can still linked with the major database to drag and change the information stored on this. SQLite Database is mostly needed by Android application development. SQLite is a freely available database management system which is specially used to perform relational functional and it comes inbuilt with android to perform database functions on android appliance. This paper will show how a message can be decrypted by using block cipher modes and which mode is more secured and fast. Keywords—Database Forensics,Mobile Device ,Android,SQLite, Modes, Tools I. INTRODUCTION In android mobile phone device, SQLite is mainly based on ACID properties docile relational database management Database is an assemble form of interrelated data which is system. -

Virtualization of the RIOT Operating System
Computer Systems and Telematics — Distributed, Embedded Systems Diploma Thesis Virtualization of the RIOT Operating System Ludwig Ortmann Matr. 3914103 Supervisor: Dr. Emmanuel Baccelli Assisting Supervisor: Prof. Dr.-Ing. Jochen Schiller Institute of Computer Science, Freie Universität Berlin, Germany March 2, 2015 iii I hereby declare to have written this thesis on my own. I have used no other literature and resources than the ones referenced. All text passages that are literal or logical copies from other publications have been marked accordingly. All figures and pictures have been created by me or their sources are referenced accordingly. This thesis has not been submitted in the same or a similar version to any other examination board. Berlin, March 2, 2015 (Ludwig Ortmann) Abstract Abstract Software developers in the growing field of the Internet of Things face many hurdles which arise from the limitations of embedded systems and wireless networking. The employment of hardware and network virtualization promises to allow developers to test and debug hard- ware independent code without being affected by these limitations. This thesis presents RIOT native, a hardware and network emulation implementation for the RIOT operating system, which enables developers to compile and run RIOT as a process in their host operat- ing system. Running the operating system as a process allows for the use of debugging tools and techniques only available on desktop computers otherwise, the integration of common network analysis tools, and the emulation of arbitrary network topologies. By enabling the use of these tools and techniques for the development of software for distributed embedded systems, the hurdles they impose on the development process are significantly reduced. -

RIOT: an Open Source Operating System for Low-End Embedded Devices in the Iot Emmanuel Baccelli, Cenk Gundo¨ Gan,˘ Oliver Hahm, Peter Kietzmann, Martine S
This article has been accepted for publication in a future issue of this journal, but has not been fully edited. Content may change prior to final publication. Citation information: DOI 10.1109/JIOT.2018.2815038, IEEE Internet of Things Journal 1 RIOT: an Open Source Operating System for Low-end Embedded Devices in the IoT Emmanuel Baccelli, Cenk Gundo¨ gan,˘ Oliver Hahm, Peter Kietzmann, Martine S. Lenders, Hauke Petersen, Kaspar Schleiser, Thomas C. Schmidt, and Matthias Wahlisch¨ Abstract—As the Internet of Things (IoT) emerges, compact low-end IoT devices. RIOT runs on minimal memory in the operating systems are required on low-end devices to ease devel- order of ≈10kByte, and can run on devices with neither MMU opment and portability of IoT applications. RIOT is a prominent (memory management unit) nor MPU (memory protection free and open source operating system in this space. In this paper, we provide the first comprehensive overview of RIOT. We cover unit). The goal of this paper is to provide an overview of the key components of interest to potential developers and users: RIOT, both from the operating system point of view, and from the kernel, hardware abstraction, and software modularity, both an open source software and ecosystem point of view. conceptually and in practice for various example configurations. We explain operational aspects like system boot-up, timers, power Prior work [28], [29] has surveyed the space of operating management, and the use of networking. Finally, the relevant APIs as exposed by the operating system are discussed along systems for low-end IoT devices. -
Introduction to Wireshark
¡ ¢ £ ¤ ¥ £ ¢ ¦ ¢ £ § ¨ ¤ © ¢ ¦ ¥ ¡ ¥ ¤ ¥ ¢ ¡ ¦ © £ £ ¨ ¡ ¥ ¢ ¨ ¡ 3 INTRODUCTION TO WIRESHARK As mentioned in Chapter 1, several packet-sniffing applications are available for performing network analysis, but we’ll focus mostly on Wireshark in this book. This chapter introduces Wireshark. A Brief History of Wireshark Wireshark has a very rich history. Gerald Combs, a computer science gradu- ate of the University of Missouri at Kansas City, originally developed it out of necessity. The first version of Combs’s application, called Ethereal, was released in 1998 under the GNU Public License (GPL). Eight years after releasing Ethereal, Combs left his job to pursue other career opportunities. Unfortunately, his employer at that time had full rights to the Ethereal trademarks, and Combs was unable to reach an agreement that would allow him to control the Ethereal brand. Instead, Combs and the rest of the development team rebranded the project as Wireshark in mid-2006. ¡ ¢ £ ¤ ¥ £ ¢ ¦ ¢ £ § ¨ ¤ © ¢ ¦ ¥ ¡ ¥ ¤ ¥ ¢ ¡ ¦ © £ £ ¨ ¡ ¥ ¢ ¨ ¡ Wireshark has grown dramatically in popularity, and its collaborative development team now boasts more than 500 contributors. The program that exists under the Ethereal name is no longer being developed. The Benefits of Wireshark Wireshark offers several benefits that make it appealing for everyday use. Aimed at both the up-and-coming and the expert packet analyst, it offers a variety of features to entice each. Let’s examine Wireshark according to the criteria defined in Chapter 1 for selecting a packet-sniffing tool. Supported protocols Wireshark excels in the number of protocols that it supports—more than 1,000 as of this writing. These range from common ones like IP and DHCP to more advanced proprietary proto- cols like DNP3 and BitTorrent. -

HDD is a hard disk drive that was conventionally used to store data, whereas SSD is a more modern and compact substitute; SSDs comprises of flash memory technology, which is the modern-day method of storing data. Though the inception of data storage began with HDD, they proved to be less accessible and stored less data as compared to the present-day SSDs, which can easily store up to 1 Terabyte in a minuscule chip-size frame. -
