PV204: Disk Encryption Lab
PV204: Disk encryption lab May 12, 2016, Milan Broz <[email protected]> Introduction Encryption can provide confidentiality and authenticity of user data. It can be implemented on several different layes, including application, file system or storage device. Application encryption examples are PGP or ZIP compression with password. Encryption of files (inside filesystem or through independent layer like Linux eCryptfs) provides more generic solution. Yet some parts (like filesystem metadata) are still unencrypted. However this solution provides encrypted data with private key per user. (Every user can have own directory encrypted by own key.) Encryption of the low-level storage (disk) is called Full Disk Encryption (FDE). It is completely transparent to the user (no need to choose what to encrypt – the whole disk is encrypted). The encrypted disk behaves as the same as a disk without encryption. The major disadvantage is that everyone who knows the password can read the whole disk. Often we combine FDE with another encryption layer. The primary use of FDE is to provide data confidentiality in power-down mode (stolen laptop does not leak user data). Once the disk is unlocked, the main encryption key remains in system, usually directly in system RAM. Exercise II will show how easy is to get this key from memory image of system. Another disadvantage of FDE is that it usually cannot guarantee integrity of data. Encryption is fully transparent and length-preserving, the ciphertext and plaintext device are of the same size. There is no space to store any integrity information. This allows attacks by direct modification of ciphertext. -

ANDROID PRIVACY THROUGH ENCRYPTION by DANIEL
ANDROID PRIVACY THROUGH ENCRYPTION by DANIEL DEFREEZ A THESIS Presented to the Department of Computer Science in partial fullfillment of the requirements for the degree of Master of Science in Mathematics and Computer Science Ashland, Oregon May 2012 ii APPROVAL PAGE “Android Privacy Through Encryption,” a thesis prepared by Daniel DeFreez in partial fulfillment of the requirements for the Master of Science in Mathematics and Computer Science. This project has been approved and accepted by: Dr. Lynn Ackler, Chair of the Examining Committee Date Pete Nordquist, Committee Member Date Hart Wilson, Committee Member Date Daniel DeFreez c 2012 iii ABSTRACT OF THESIS ANDROID PRIVACY THROUGH ENCRYPTION By Daniel DeFreez This thesis explores the field of Android forensics in relation to a person’s right to privacy. As the field of mobile forensics becomes increasingly sophisticated, it is clear that bypassing common privacy measures, such as disk encryption, will become routine. A new keying method for eCryptfs is proposed that could significantly mitigate memory attacks against encrypted file systems. It is shown how eCryptfs could be modified to implement this keying method on an Android device. iv ACKNOWLEDGMENTS I would like to thank Dr. Lynn Ackler for introducing me to the vast world of computer security and forensics, cultivating a healthy paranoia, and for being a truly excellent teacher. Dr. Dan Harvey, Pete Nordquist, and Hart Wilson provided helpful feedback during the preparation of this thesis, for which I thank them. I am deeply indebted to my friends and colleagues Brandon Kester, Andrew Krug, Adam Mashinchi, Jeff McJunkin, and Stephen Perkins, for their enthusiastic interest in the forensics and security fields, insightful comments, love of free software, and encouraging words. -

Praise for The Official Ubuntu Book “The Official Ubuntu Book is a great way to get you started with Ubuntu, giving you enough information to be productive without overloading you.” —John Stevenson, DZone Book Reviewer “OUB is one of the best books I’ve seen for beginners.” —Bill Blinn, TechByter Worldwide “This book is the perfect companion for users new to Linux and Ubuntu. It covers the basics in a concise and well-organized manner. General use is covered separately from troubleshooting and error-handling, making the book well-suited both for the beginner as well as the user that needs extended help.” —Thomas Petrucha, Austria Ubuntu User Group “I have recommended this book to several users who I instruct regularly on the use of Ubuntu. All of them have been satisfied with their purchase and have even been able to use it to help them in their journey along the way.” —Chris Crisafulli, Ubuntu LoCo Council, Florida Local Community Team “This text demystifies a very powerful Linux operating system . in just a few weeks of having it, I’ve used it as a quick reference a half dozen times, which saved me the time I would have spent scouring the Ubuntu forums online.” —Darren Frey, Member, Houston Local User Group This page intentionally left blank The Official Ubuntu Book Sixth Edition This page intentionally left blank The Official Ubuntu Book Sixth Edition Benjamin Mako Hill Matthew Helmke Amber Graner Corey Burger With Jonathan Jesse, Kyle Rankin, and Jono Bacon Upper Saddle River, NJ • Boston • Indianapolis • San Francisco New York • Toronto • Montreal • London • Munich • Paris • Madrid Capetown • Sydney • Tokyo • Singapore • Mexico City Many of the designations used by manufacturers and sellers to distinguish their products are claimed as trademarks. -

Cde: a Reduce Package for Integrability of Pdes Version 2.0
CDE: A REDUCE PACKAGE FOR INTEGRABILITY OF PDES VERSION 2.0 R. VITOLO Abstract. We describe CDE, a Reduce package devoted to differential-geometric computations on Differential Equations (DEs, for short). The package is included in the official Reduce sources in Sourceforge [37] and it is also distributed on the Geometry of Differential Equations web site http://gdeq.org (GDEQ for short). We start from an installation guide for Linux and Windows. Then we focus on con- crete usage recipes for computations in the geometry of differential equations: higher symmetries, conservation laws, Hamiltonian operators and their Schouten bracket, re- cursion operators. All programs discussed here are shipped together with this manual and can be found in the Reduce sources or at the GDEQ website. The mathematical theory on which computations are based can be found in refs. [12, 22]. Contents 1. Introduction: why CDE? 2 2. Installation 3 2.1. Installation of Reduce 3 2.2.
