A Study of the Nature of the Photochromic Mechanism in Various Sodalites
A STUDY OF THE NATURE OF THE PHOTOCHROMIC MECHANISM IN VARIOUS SODALITES by RICHARD MARTIN CHARNAH B. Sc., A.R.C.S. A Thesis submitted for the Degree of Doctor of Philosophy in the University of London. September 1973 Department of Electrical Engineering IMPERIAL COLLEGE University of London • - Abstract The major inorganic photochromic materials are reviewed, and in particular sodalite in greater detail. The growth of sodalites by hydrothermal and fluxed- melt techniques and by a low temperature aqueous medium method from kaolinite is dealt with, and the production of a novel material with more convenient activation properties than hitherto is described. Using chiefly epr measurements and spectra reconstructions the electron centres previously suggested as the source of the photochromic activity are eliminated and a new model developed, though others are also considered possible. Other effects in sodalites are explained using configuration co-ordinate diagrams, and suggestions are made concerning non-photochromic sodalites. • To my wife, Haze • - iv - Acknowledgements I would like to thank Dr D W G Ballentyne for his encouragement and supervision during this work. I am also grateful to Dr E A D White for advice on crystal growth, to Professor J C Anderson for his interest and support and to Dr J F Gibson for providing unhindered access to the Varian epr spectrometer and with whom I had many illuminating discussions. May I also thank my colleagues and friends of the materials section for their advice and criticism and for the environment they created, and the technical staff of the electrical engineering department, especially Mr P Robinson whose guidance on hardware saved much time. -

Keeping Secrets in Hardware: the Microsoft Xboxtm Case Study
Keeping Secrets in Hardware: The Microsoft XboxTM Case Study Andrew Huang Massachusetts Institute of Technology, Cambridge MA 02139, USA, [email protected], http://www.xenatera.com/bunnie/ Abstract. This paper discusses the hardware foundations of the cryp- tosystem employed by the XboxTM video game console from Microsoft. A secret boot block overlay is buried within a system ASIC. This secret boot block decrypts and verifies portions of an external FLASH-type ROM. The presence of the secret boot block is camouflaged by a decoy boot block in the external ROM. The code contained within the secret boot block is transferred to the CPU in the clear over a set of high-speed busses where it can be extracted using simple custom hardware. The paper concludes with recommendations for improving the Xbox security system. One lesson of this study is that the use of a high-performance bus alone is not a sufficient security measure, given the advent of inexpensive rapid prototyping services and affordable high-performance FPGAs. 1 Introduction and Background Every cryptosystem is based on some kind of secret, such as a key. Regardless of the cipher, the security of a cryptosystem is only as strong as the secrecy of the key. Thus, some of the most startlingly effective attacks on a cryptosystem involve no ciphertext analysis, but instead find flaws in the protocols that manage the keys. Cryptosystems based on symmetric ciphers are particularly vulnerable to protocol attacks, since both the sender and the receiver must be trusted to have a copy of the same secret key. -
A Study of the Application of Free and Open Source Software Licensing Ideas to Art and Cultural Production
Sandbox Culture A Study of the Application of Free and Open Source Software Licensing Ideas to Art and Cultural Production Aymeric Mansoux Supervisor: Matthew Fuller Thesis presented for the degree of Doctor of Philosophy Centre for Cultural Studies, Goldsmiths, University of London, February 2017 I, Aymeric Mansoux, confirm that the work presented in this thesis ismy own. Where information has been derived from other sources, I confirm that this has been indicated in the thesis. Date: February 19, 2017 Signed: Abstract In partial response to the inability of intellectual property laws to adapt to data-sharing over computer networks, several initiatives have proposed techno-legal alternatives to encourage the free circulation and transfor- mation of digital works. These alternatives have shaped part of contem- porary digital culture for more than three decades and are today often associated with the “free culture” movement. The different strands of this movement are essentially derived from a narrower concept of soft- ware freedom developed in the nineteen-eighties, and which is enforced within free and open source software communities. This principle was the first significant effort to articulate a reusable techno-legal template to work around the limitations of intellectual property laws. It also of- fered a vision of network culture where community participation and sharing was structural. From alternate tools and workflow systems, artist-run servers, net- work publishing experiments, open data and design lobbies, cooperative and collaborative frameworks, but also novel copyright licensing used by both non-profit organisations and for-profit corporations, the impact on cultural production of practices developed in relation to the ideas of iii free and open source software has been both influential and broadly ap- plied. -

Following the author’s self-publication of the book (during which time he sold thousands directly), Hacking the Xbox is now brought to you by No Starch Press. Hacking the Xbox begins with a few step-by-step tutorials on the Xbox hardware modifications that teach basic hacking techniques as well as essential reverse engineering skills. It progresses into An Introduction to Reverse Engineering a discussion of the Xbox security mechanisms and other advanced hacking topics, emphasizing the important subjects of computer security and reverse engineering. The book includes numerous practical guides, such as where to get hacking gear, soldering techniques, debugging tips, and an Xbox hardware reference guide. Hacking the Xbox confronts the social and political issues facing today’s hacker, and introduces readers to the humans behind the hacks through several interviews with master hackers.

This lawsuit challenges the “anti-circumvention” and “anti-trafficking” provisions of the Digital Millennium Copyright Act (“DMCA”), 17 U.S.C. §§ 1201(a), 1203, and 1204 (collectively “the DMCA Anti-Circumvention Provisions”). Enacted in 1998, these provisions broadly restrict the public’s ability to access, speak about, and use copyrighted materials, without the traditional safeguards—such as the fair use doctrine—that are necessary to protect free speech and allow copyright law to coexist with the First Amendment. The threat of enforcement of these provisions chills protected and noninfringing speech that relies on copyrighted works, including independent technical research into computer security systems and the discussion of that research, and accessing copyrighted works in order to shift the content to a different format, space, or time. -
