Rc-6 Cryptosystem in Vhdl
RC-6 CRYPTOSYSTEM IN VHDL BY:- Deepak Singh Samant OBJECTIVE: TO IMPLEMENT A CRYPTOSYSTEM USING RIVEST CIPHER-6 (RC6) ALGORITHM IN VHDL(FPGA) What is CRYPTOLOGY? CRYPTOGRAPHY is the art and science of achieving security by encoding message to make them non-readable . CRYPTANALYSIS is the technique of decoding messages from a non-readable format back to readable format without knowing how they were initially converted from readable format to non-readable format. CRYPTOGRAPHY + = CRYPTOLOGY CRYPTANALYSIS Cryptography Overview: Comm. E(k) N/W D(k) Key Set K Key Set K Types Of Attacks: . General View: 1.Criminal Attack 2.Publicity Attack 3.Legal Attack .Technical View: oPassive Attacks oActive Attacks Release of message Interruption Traffic Attacks Modification Fabrication Symmetric key cryptography If same key is used for encryption and decryption,we call the mechanism as symmetric key cryptography. It has the key distribution problem. Symmetric key cryptography Algorithm DES IDEA RC4 RC5 BLOW AES FISH AES: US government wanted to standardize a cryptographic algorithm,which was to be used universally by them.It was to be called as the Advanced Encryption Standard(AES). Among various proposal submitted,only 5 were short listed: 1.Rijndael 3.Serpent 5.MARS 2.Twofish 4.RC6 LITERATURE SURVEY • Comparison: (1) MARS: Its throughput in the studies was generally low. Therefore, its efficiency (throughput/area) was uniformly less than the other finalists. (2) RC6 throughput is generally average. RC6 seems to perform relatively better in pipelined implementations, non-feedback mode (3) Rijndael: good performance in fully pipelined implementations. Efficiency is generally very good. 4) Serpent: feedback mode encryption. -

DSTAC WG3 Report I. Introduction A. DSTAC Mission The DSTAC's mission is "to identify, report, and recommend performance objectives, technical capabilities, and technical standards of a not unduly burdensome, uniform, and technology- and platform-neutral software-based downloadable security system" to promote the competitive availability of navigation devices (e.g., set-top boxes and television sets) in furtherance of Section 629 of the Communications Act. The DSTAC must file a report with the Commission by September 4, 2015 to detail findings and recommendations. [DSTAC Mission, www.fcc.gov/dstac] B.

Tuesday 13 November 2007
Tuesday 13 November 2007 RE: Response to the proposed BSkyB digital terrestrial television services consultation I wish to start by personally thanking you for allowing me to respond to the plans that British Sky Broadcastings plans to launch their Picnic platform on Digital Terrestrial Television, including the launch of the following services: z Sky Sports One; z A children's channel/Sky Movies SD One; z A factual channel/Sky News/Sky One; z Sky News (if BSkyB is given permission to launch a fourth service on DTT using MPEG-4 encoding); z Broadband up to 16Mbps and a telephony service. I wish to begin by giving an idea of my thoughts on the proposal by BSkyB before I answer the questions in the consultation document. Introduction 1. Regarding the use of by BSkyB and NDS Group, the VideoGuard conditional access technology for its pay television services. According to the press release that was released by BSkyB on the 8th of February 2007,1 the service will use a highly secure conditional access system similar to the one BSkyB uses for its digital satellite services, Sky Digital and FreesatFromSky. I also understand that Sky has also stated that viewers will require a new set-top-box to access the new service. In the past, since the launch of the Sky satellite television service in February 1989 via the Astra satellite, BSkyB have always used NDS Group technology to encrypt and protect their own branded services, with both the VideoCrypt and VideoGuard conditional access systems for their Sky analogue and digital satellite services respectively. -

UBRARIES Traitor Tracing through Function Sharing by Cem Q~elebiler Submitted to the Department of Electrical Engineering and Computer Science on December 15, 1995, in partial fulfillment of the requirements for the degrees of Master of Engineering and Bachelor of Science in Computer Science and Engineering Abstract To broadcast information (for example pay-television) over insecure channels (for ex- ample the public airwaves) to a set of paying subscribers, the broadcaster may employ encryption to prevent non-subscribers from gaining access to the programming. A risk to the broadcaster is that subscribers may sell or give their decryption key to non-subscribers and thus deprive the broadcaster of potential revenue. Traitor trac- ing schemes are key management schemes that allow the broadcaster to trace any subscriber who sells his key. -
Study on the Use of Conditional Access Systems for Reasons Other Than The
Study on the use of conditional access systems for reasons other than the protection of remuneration, to examine the legal and the economic implications within the Internal Market and the need of introducing specific legal protection Report presented to the European Commission by N. Helberger N. A. N. M. van Eijk P. B. Hugenholtz Institute for Information Law (IViR) University of Amsterdam Preface The study, commissioned by the Directorate-General for Internal Market and Financial Services (DG XV) of the Commission of the European Community, offers an analysis of the use of conditional access systems for other reasons than the protection of remuneration interests. The report also examines the need to provide for additional legal protection by means of a Community initiative, such as a possible extension of the Conditional Access Directive. The report will give a legal and economic analysis of the most important non- remuneration reasons to use conditional access (CA), examine whether services based on conditional access for these reasons are endangered by piracy activities, to what extent existing legislation in the Member States provides for sufficient protection, and what the possible impact of the use of conditional access is on the Internal Market. Furthermore, the study analysis the specific legislation outside the European Union, notably in Australia, Canada, Japan and the US, as well as the relevant international rules at the level of the EC, WIPO and the Council of Europe. This study was written by Natali Helberger and Dr Nico A. N. M. van Eijk at the Institute for Information Law (IViR), University of Amsterdam under the supervision of Professor P. -

The RC6TM Block Cipher
TM The RC6 Blo ck Cipher 1 2 2 2 Ronald L. Rivest , M.J.B. Robshaw , R. Sidney , and Y.L. Yin 1 M.I.T. Lab oratory for Computer Science, 545 Technology Square, Cambridge, MA 02139, USA [email protected] 2 RSA Lab oratories, 2955 Campus Drive, Suite 400, San Mateo, CA 94403, USA fmatt,ray,[email protected] Version 1.1 - August 20, 1998 TM Abstract. We intro duce the RC6 blo ck cipher. RC6 is an evolu- tionary improvementofRC5, designed to meet the requirements of the Advanced Encryption Standard AES. LikeRC5, RC6 makes essential use of data-dep endent rotations. New features of RC6 include the use of four working registers instead of two, and the inclusion of integer multi- plication as an additional primitive op eration. The use of multiplication greatly increases the di usion achieved p er round, allowing for greater security, fewer rounds, and increased throughput. 1 Intro duction TM RC6 is a new blo ck cipher submitted to NIST for consideration as the new Advanced Encryption Standard AES. The design of RC6 b egan with a consideration of RC5 [18] as a p otential candidate for an AES submission. Mo di cations were then made to meet the AES requirements, to increase security, and to improve p erformance. The inner lo op, however, is based around the same \half-round" found in RC5. RC5 was intentionally designed to be extremely simple, to invite analysis shedding light on the security provided by extensive use of data-dep endent ro- tations. Since RC5 was prop osed in 1995, various studies [2, 5, 8, 11, 15, 19] have provided a greater understanding of howRC5's structure and op erations contribute to its security.
