  • A Traitor Tracing Scheme Based on RSA for Fast Decryption
    A Traitor Tracing Scheme Based on RSA for Fast Decryption John Patrick McGregor, Yiqun Lisa Yin, and Ruby B. Lee Princeton Architecture Laboratory for Multimedia and Security (PALMS) Department of Electrical Engineering Princeton University {mcgregor,yyin,rblee}@princeton.edu Abstract. We describe a fully k-resilient traitor tracing scheme that uti- lizes RSA as a secret-key rather than public-key cryptosystem. Traitor tracing schemes deter piracy in broadcast encryption systems by enabling the identification of authorized users known as traitors that contribute to unauthorized pirate decoders. In the proposed scheme, upon the confis- cation of a pirate decoder created by a collusion of k or fewer authorized users, contributing traitors can be identified with certainty. Also, the scheme prevents innocent users from being framed as traitors. The pro- posed scheme improves upon the decryption efficiency of past traitor tracing proposals. Each authorized user needs to store only a single de- cryption key, and decryption primarily consists of a single modular expo- nentiation operation. In addition, unlike previous traitor tracing schemes, the proposed scheme employs the widely deployed RSA algorithm. 1 Introduction Broadcast encryption is beneficial in scenarios where a content provider wishes to securely distribute the same information to many users or subscribers. The broadcast content is protected with encryption, and only legitimate users should possess the information (e.g., decryption keys) necessary to access the content. These keys can be embedded in software or in tamper-resistant hardware devices such as smart cards. Current tamper-resistant hardware is vulnerable to a variety of attacks [1], however. Furthermore, truly tamper-resistant software, which includes programs that resist unauthorized tampering or inspection of code and data, has yet to be developed.

  • Ka-Band Satellite Consumer Triple-Play and Professional Video Services
    Ka-Band Satellite Consumer Triple-Play and Professional Video Services Guillaume Benoit, Hector Fenech, Stefano Pezzana, and Alessia Tomatis Eutelsat, 70 rue Balard, 75015 Paris, France +33 1 53 98 47 47 {gbenoit,hfenech,spezzana,atomatis}@eutelsat.fr Abstract. This article presents Eutelsat European Ka-band implementation of the broadband ToowayTM service and its evolution through a dedicated Ka-band exclusive satellite (KA-SAT). It also explains Eutelsat’s choice in se- lecting the Ka-band for interactive services, broadcast video and IPTV ser- vices, demonstrating the optimal consumer service synergy between existing Ku-band and new Ka-band services. KA-SAT satellite is not focusing only on consumer triple-play services. In- deed, Eutelsat strategy consists in offering also professional video and data services in Ka-band (video distribution, video contribution, e-cinema, file transport) sharing the same transparent satellite bandwidth and the same ground segment infrastructure. For those professional video applications the last content processing (SVC) and satellite transport (DVB-S2 ACM) techniques are under deployment and this paper will present simulation results and link budgets estimations for a large number of future commercial applications. 1 Introduction Eutelsat operates 25 satellites in the geostationary arc from 15°W to 70.5°E offering a variety of services from corporate networks to broadcasting. The HOT BIRD™ con- stellation at 13°E constitutes the prime position for DTH (Direct to Home) and cable broadcasting, utilizing the full Ku-band spectrum from 10.70 GHz to 12.75 GHz. There are 102 transponders delivering about 1400 TV channels. The HOT BIRD™ service area reaches some 120 million satellite and cable households.

  • EUTELSAT's W3C SATELLITE in FULL COMMERCIAL SERVICE New W3C and ATLANTIC BIRD™ 7 Satellites Inject Additional Resources
    PR/72/11 EUTELSAT’s W3C SATELLITE IN FULL COMMERCIAL SERVICE New W3C and ATLANTIC BIRD™ 7 satellites inject additional resources and flexibility into Eutelsat’s fleet Paris, 9 November 2011 Eutelsat Communications (Euronext Paris: ETL) today announced the full entry into commercial service of the powerful W3C satellite at 16° East. The transfer of all traffic, including over 480 television channels, onto W3C from the EUROBIRD™ 16, W2M and SESAT 1 satellites was completed this morning by Eutelsat’s control centre, working in close collaboration with clients and providers of uplink services. With the high-capacity W3C going on-line at 16° Eas t, Eutelsat is further equipped to service dynamic satellite broadcasting markets in Central Europe and Indian Ocean islands. Over 11 million homes in Central Europe and 500,000 in Indian Ocean islands are already equipped to receive broadcast services from this longstanding Eutelsat neighbourhood. Pay-TV platforms and public and private broadcasters using W3C include SBB, Digitalb, TV Max, Tring and TV Romania that are addressing Central Europe via a high-power footprint optimised for the region. A second regional footprint centred over Madagascar and Indian Ocean islands is serving the Canal+ Overseas, Parabole Réunion and Orange platforms as well as France Télévisions to support digital switchover in Reunion Island and Mayotte. SBB, operator of Total TV, the leading DTH platform in the Adriatic region, is taking immediate benefit from W3C’s increased capacity to add two transponders to the six already leased at 16° East. SBB's additional capaci ty, leased to 2020, will be used to support a number of new channels in all of Total TV's markets.

  • Ariane-DP GB VA209 ASTRA 2F & GSAT-10.Indd
    A DUAL LAUNCH FOR DIRECT BROADCAST AND COMMUNICATIONS SERVICES Arianespace will orbit two satellites on its fifth Ariane 5 launch of the year: ASTRA 2F, which mainly provides direct-to-home (DTH) broadcast services for the Luxembourg-based operator SES, and the GSAT-10 communications satellite for the Indian Space Research Organization, ISRO. The choice of Arianespace by the world’s leading space communications operators and manufacturers is clear international recognition of the company’s excellence in launch services. Based on its proven reliability and availability, Arianespace continues to confirm its position as the world’s benchmark launch system. Ariane 5 is the only commercial satellite launcher now on the market capable of simultaneously launching two payloads and handling a complete range of missions, from launches of commercial satellites into geostationary orbit, to dedicated launches into special orbits. Arianespace and SES have developed an exceptional relationship of mutual trust over more than 20 years. ASTRA 2F will be the 36th satellite from the SES group (Euronext Paris and Luxembourg Bourse: SESG) to use an Ariane launcher. SES operates the leading direct-to-home (DTH) TV broadcast system in Europe, based on its Astra satellites, serving more than 135 million households via DTH and cable networks. Built by Astrium using a Eurostar E3000 platform, ASTRA 2F will weigh 6,000 kg at launch. Fitted with active Ku- and Ka-band transponders, ASTRA 2F will be positioned at 28.2 degrees East. It will deliver new-generation DTH TV broadcast services to Europe, the Middle East and Africa, and offers a design life of about 15 years.
