Over 2 billion GSM subscribers)

3 billion subscribers expected by end of 2010 (Ovum).

Digital Convergence

Television

Mobile Communications

Television

  • Over 4 billion users

Mobile TV

  • Attractive new services

  • Easy to understand

The return channel

Mobile Broadcaster

(DVB-H)

Mobile Netowrk Operator

(GSM, GPRS, UMTS)

The Return Channel

  • Mobile Broadcasting networks and cellular networks (GSM, GPRS or UMTS) are complementary to Mobile TV services.

  • The cellular networks provide a ‘return channel’ for:

    • Service request

    • Service charging/payment

    • Video-on-Demand (VOD)

    • Other interactive services (voting, betting, information)

Company confidential: Internal usage only.


Challenges facing mobile tv

  • Regulatory factors

    • Frequency allocation and Licensing

  • Technology factors

    • Standardization,

    • Availability of terminals

    • Interoperability

  • Network (reception in mobile situation)

    • Similar to Cellular networks

    • Delivery costs low enough for a profitable value chain

    • International roaming ?

  • Service & Content Protection

    • To set up a trustworthy environment

    • To secure revenue streams

Challenges facing Mobile TV

  • A true consumers’ value proposition (not simply a technology)

    • Content (Live TV / TV-on demand / Push TV, not simply a rebroadcast of terrestrial content)

    • Relevant Services (Interactivity, ESG and additional information)

    • Positive user experience (Easy to use & easy to pay service)

    • Value for money & Straightforward pricing

  • Consumers

    • Demand and acceptance

  • Business factors

    • Business models

    • Co-operation along the value chain (“win-win”)

Why service content protection

Why Service & Content Protection?

  • Service and Content protection is critical for the success of mobile business models.

Content Owners

Service Providers

Consumers

  • Want to protect their return on investment

  • Want to build a

    trustworthy network

  • Want to optimize revenues through multiple subscription models

  • Want to protect the

    rights of their assets,

    and to control their

    consumption

  • Want to secure revenues

  • Want Trust in the

    delivery mechanism

  • Prepared to pay for

    premium content.

  • Want choice and flexibility in the way they consume

    content.

Company confidential: Internal usage only.


Service content protection

Service & Content Protection

Re-Distribution

Live Broadcast

Service Protection

Content Protection

Ensures that only paying

customers have access to content

Solution:

Conditional Access (CA)

Controls the use of content

once it has reached the device

Solution:

Digital Rights Management (DRM)

The two technologies can work together to

protect recorded content !

Downloading services to mobiles

Downloading Services to Mobiles

  • Mobile phones have evolved into multimedia devices

  • Technologies enable efficient delivery of rich multimedia content (from ring tones to live TV) to mobiles

Pictures

Ringtones

Games

Video clips

Peer-to-peer connection

Music MP3

Company confidential: Internal usage only.


Mobile drm

Mobile DRM

Rich multimedia content

is delivered to mobile devices

Protects the interests

of the content rights owner,

by providing a way to control

access to the use and

consumption of digital content

Opportunity to define new ways of selling,

distributing and consuming content

Standards

Standards

  • Many proprietary standards (e.g. Microsoft, iTunes)

  • Open standard specified by OMA

    • The Open Mobile Alliance (OMA) is a mobile industry organization dedicated to promoting the worldwide adoption of mobile data services by emphasizing interoperability across devices and networks.

    • OMA was formed in June 2002. The 350 member companies represent the world’s leading mobile operators, device and network suppliers, information technology companies, application developers and content providers.

    • OMA DRM specifications released:

      • OMA DRM 1.0 (2004)

      • OMA DRM 2.0 (2006)

    • The IPR licensing terms & conditions are defined by the CMLA (Content Management License Administrator) which is a licensing and compliance entity formed to provide a full solution implementation of OMA DRM 2.0.

Drm not suitable for mobile tv

DRM not suitable for Mobile TV

  • Device-based DRM does not work for Mobile TV

    • “Japanese mobile giant NTT DoCoMo is scrambling to release a new version of its popular mobile TV handset after unscrupulous users found a loophole allowing them to watch free mobile TV.” (loss of €250 per handset)

  • A breach in Microsoft DRM

    • “A program called Fairuse4wm has been posted on the net and is said to be capable of bypassing Microsoft’s Digital Rights Management (DRM) system.”

    • “BSkyB has suspended its Sky by Broadband movie service until Microsoft patches a security loophole in its Windows DRM technology”

  • Fixing DRM does not work !

    • "DRM is fundamentally an impossible problem. Making it work at all involves tricks, and breaking DRM is akin to "fixing" the software so the tricks don't work. Anyone looking for a demonstration that technical DRM is doomed should watch this story unfold.” (Bruce Schneier on Microsoft DRM, 15 October 2006)

Osf vs 18crypt

OSF vs. 18Crypt

Issue with 18Crypt when a breach occurs:

  • Does the MNO have a dedicated and specialized team to investigate hacked phones?

  • Who is liable?

    • Handset manufacturers will deny responsibility as they comply with standard requirements. Moreover there might be a conflict of interest as a hacked phone might generate more handset sales

    • Stack provider, software vendor, OS provider, …??

  • If the handset manufacturer does not solve the breach the content owner will stop providing content and start legal action

  • The keys of the phone can be revoked. But if one phone is pirated all phones in that model are very likely to be pirated. And this might lead to high operational costs to manage phone replacement or customer complaints

Adapting CA solution to Mobile

  • Mature & proven CA technologies available for Mobile service protection

  • Irdeto has developed two innovative technologies:

    • Dual Key Hierarchy – limits bandwidth required for key exchange

    • Rapid Refresh – increases security through rapid cycling of rights

  • Mobile subscribers may be roaming orpowered down for significant periods, but demand immediate gratification. The delivery of EMMs Over The Air (OTA) helps in reducing costs and ensures their rapid delivery to the device.

Hardware component

Hardware Component

  • Irdeto supports 2 secure hardware components:

    • SMD (Surface Mounted Device)

    • SIM (Subscriber Identity Module)

  • SMD can be supplied by Irdeto to manufacturer to be placed directly on the chipboard of their device. This is adapted for:

    • Non-connected devices (PDAs, Portable Multimedia Players (PMPs), in-car devices)

    • Phones without SIMs (CDMA phones)

  • SIM is a smart card that securely stores the key identifying a mobile phone service subscriber, as well as subscription information, preferences and text messages. The equivalent of a SIM in UMTS is a Universal Subscriber Identity Module (USIM). Irdeto will place its secure Java applet on the existing MNOs SIM card.

Company confidential: Internal usage only.


Benefits of the u sim

Benefits of the (U)SIM

  • The (U)SIM is owned by the MNOs. It is their only asset in the mobile device. MNOs have full control over it. With DVB-H and an Irdeto CA solution, MNOs will keep ownership of their subscriber base.

  • The (U)SIM is a tamper resistant device and as such, it offers high levels of security. With the Irdeto CA solution, the (U)SIM handles all security related processing (ECMs and EMMs).

  • The (U)SIM offers easy-to-manage customer relationship. Customer management and service provisioning can be handled via the OTA server. In addition, security updates can be managed without swapping terminals or impacting the customer experience.

  • Irdeto’s basic requirements for the (U)SIM are:

    • JavaCard V2.1.2 & Global Platform V2.1.1

    • Irdeto applet size on (U)SIM: ~30K

    • Other security related requirements (available upon request).
