Handout 5 Summary of This Handout: Stream Ciphers — RC4 — Linear Feedback Shift Registers — CSS — A5/1
06-20008 Cryptography The University of Birmingham Autumn Semester 2009 School of Computer Science Volker Sorge 30 October, 2009 Handout 5 Summary of this handout: Stream Ciphers — RC4 — Linear Feedback Shift Registers — CSS — A5/1 II.2 Stream Ciphers A stream cipher is a symmetric cipher that encrypts the plaintext units one at a time and that varies the transformation of successive units during the encryption. In practise, the units are typically single bits or bytes. In contrast to a block cipher, which encrypts one block and then starts over again, a stream cipher encrypts plaintext streams continuously and therefore needs to maintain an internal state in order to avoid obvious duplication of encryptions. The main difference between stream ciphers and block ciphers is that stream ciphers have to maintain an internal state, while block ciphers do not. Recall that we have already seen how block ciphers avoid duplication and can also be transformed into stream ciphers via modes of operation. Basic stream ciphers are similar to the OFB and CTR modes for block ciphers in that they produce a continuous keystream, which is used to encipher the plaintext. However, modern stream ciphers are computationally far more efficient and easier to implement in both hard- and software than block ciphers and are therefore preferred in applications where speed really matters, such as in real-time audio and video encryption. Before we look at the technical details how stream ciphers work, we recall the One Time Pad, which we have briefly discussed in Handout 1. The One Time Pad is essentially an unbreakable cipher that depends on the fact that the key 1. -

The MPAA runs a comprehensive anti-piracy program that includes investigative, educational, legislative, and technical efforts in the United States and over 70 other countries.

The High-Definition Multimedia Interface
technology High-Defi nition Multimedia Interface It’s the interconnect that sorts out a lot of problems we thought we had and a few that we didn’t; it’s the High-Defi nition Multimedia Interface. NIGEL JOPSON discovers a new digital connector that has all sorts of implications for the future — including the forced deactivation of analogue outputs. just 15% of new sets sold this year will include it and be able to deliver the full 1080 high resolution picture that these devices are being sold on. Unlike the disparate disc formats that have polarised manufacturers into two camps, the HDMI connector has cross-industry support. The founders include electronics manufacturers Hitachi, Matsushita Electric (Panasonic), Philips, Sony, Thomson (RCA), Toshiba, and Silicon Image. Digital Content Protection LLC (a subsidiary of Intel) is providing High-bandwidth Digital Content Protection (HDCP) for HDMI. In addition, HDMI has the very partisan support of major movie producers Fox, Universal, Warner Bros and Disney, and system operators DirecTV and EchoStar (Dish Network) as well as CableLabs and Samsung. So HDMI is an industry-supported, uncompressed, all-digital audio/video interface. The small connector provides the interface between any compatible digital audio/video source, such as a set-top box, DVD player or AV receiver and a compatible digital audio and/or video monitor. It was conceived as a sort of digital SCART, primarily a point-to-point connector; HDMI grew out of DVI and the picture side is backwards compatible (providing that copy protection is implemented). HDMI adds support for component video, multichannel audio, the so-called universal CD control, and the concept of auto-confi guration. -

Cryptography 2006 the Rise and Fall of Dvd Encryption
CRYPTOGRAPHY 2006 THE RISE AND FALL OF DVD ENCRYPTION by Kim Rauff Schurmann, 20033033 ([email protected]) Claus Andersen, 20030583 ([email protected]) Jacob Styrup Bang 20030585 ([email protected]) Jakob Løvstad Funder 20033047 ([email protected]) Department of Computer Science - Daimi University of Aarhus December 15, 2006 Abstract The motivation for this project is to understand the failures made in the past in order to avoid repeating them. There were two main reasons for the fall of DVD encryption. One is a very insecure cryptosystem and the other is poor key management. Our focus will be on the former and we will spend a great deal of time describing and analyzing CSS, and the attacks on it. To fully understand and demonstrate those attacks, we will implement two of the attacks.. These are not the only two, but should be enough to understand the weaknesses in CSS This paper is for a large part based on information retrieved by reverse engineering CSS. This is because the DVD encryption was supposed to be a closed source encryption scheme. As a closure we will take a short look on the succeeding encryption schemes for HD-DVD and Blu-ray and what have been learned from the failures of CSS.

Of Price Discriminiation, Rootkits and Flatrates
Of Price Discriminiation, Rootkits and Flatrates Volker Grassmuck Helmholtz-Zentrum für Kulturtechnik, Humboldt-University Berlin 19 February 2006 DRAFT VERSION – final version is slated for print publication Licensed under Creative Commons Share-Alike Germany 2.0 „Copyright owners continue to be ambivalent about the Internet. On the one hand, it represents a fantastic new medium for distribution; on the other, many in the publishing industry see it as one ‚giant, out of control copying machine.‘ ... The very technological advances that make rights management more difficult – the dramatic reduction in costs of copying and distribution – also offer a fantastic opportunity for owners of intellectual content.“1 Without scarcity there is no market. Information by its nature is a public good.2 Copyright law artificially creates scarcity by granting exclusive rights to it for a limited time. Media technology so far helped enforcability of those rights because the means of production and the means of distribution of informational goods were expensive and therefore scarce. The digital revolution does away with this scarcity. PC and Internet bring to virtually everyone the power of the printing press and the recording studio. Only now, information‘s defining qualities of non-rivalrousness and non-excludability come to full bearing. Zero cost for reproduction and distribution is indeed a fantastic value proposition for information vendors. Alas, it is undermined by the fact that for consumers the cost of copying and distribution is zero as well. Peer-to-peer networks show that transporting bits from A to B is now such a low-cost service that users can effortlessly provide it to each other. -
