OMA Smart Card Web Server (SCWS)

As mobile applications and services become increasingly sophisticated and complex, the requirements for managing and distributing content-rich applications present new challenges. OMA Smart Card Web Server meets these requirements and addresses the latest trends in the evolution of Smart Card technology.

OMA SCWS provides a next generation user interface, moving from black and white menus to rich, Web-like “look and feel” capabilities. Additionally, OMA SCWS enhances connectivity with remote Web servers to enable client server applications to take full advantage of the evolution in network speeds.

OMA SCWS enables both static and dynamic Web pages, allowing local communication (i.e. transactions) between the SCWS and an HTTP based application such as a Web browser running in a handset. This facilitates the implementation of mobile operators’ services, making them portable across all handsets. OMA SCWS Enabler also specifies remote administration of SCWS content over HTTP(s).

OMA SCWS V1.1 was approved in May 2009. OMA SCWS V1.2 reached Candidate status in April 2011 and is expected to reach final approval in October 2012. OMA SCWS V1.2 offers several enhancements to SCWS V1.1:

  • Clarification of the SCWS implementation when the Smart Card supports a full TCP/IP stack on top of the USB-IC (InterChip) interface.
  • Improvements to the SCWS remote administration involving third parties and improvements to the definition of memory polls where static resources of a third party are allocated.
  • Specification for the usage of the latest versions of TLS (Transport Layer Security), TLS 1.1 and TLS 1.2.
  • Improvement to security for applications in the handset accessing the SCWS content: the implementation of the Access Control Policy enforcer becomes mandatory for the handset – for example, only permitted applications have access to the SCWS.
  • In order to trigger a remote administration session to update the content of the SCWS, the usage of a SIP Push message has been defined in addition to the Push SMS. This reuses the OMA SIP Push Enabler.

The Importance of Standardization

The creation of a global SCWS standard facilitates the interoperability between the device and the Smart Card and between the Administration server and the Smart Card. Additionally, OMA's SCWS standard ensures seamless portability between devices and ensures a consistent end-user experience.

Benefits of OMA Smart Card Web Server for Operators and Customers

Operator Benefits

  • OMA SCWS is a standard platform to remotely manage Web content.
  • OMA SCWS acts as a Web server in the Smart Card (e.g. a (U)SIM).
  • OMA SCWS supports mobile commerce and the adoption of mobile Near Field Communications services.
  • Mobile operators’ (U)SIM applications such as (U)SIM Toolkit applications benefit from an enhanced Web “look and feel” using the browser’s multimedia capabilities.
  • OMA SCWS acts as a means to deploy secure services with standard Web technology leveraging inherent Smart Card security features.

Customer Benefits

  • OMA SCWS improves accessibility of Smart Card content from the user interface of any handset.
  • OMA SCWS is accessible at all times.
  • OMA SCWS supports mobile commerce and the adoption of mobile Near Field Communications services.

Basic Use Cases for OMA Smart Card Web Server

Smart Card Web Server Case 1Use Case 1: Quick and Simple Access to Operator Services – Web Portal
Using the browser on any handset, OMA SCWS enables service discovery based on local content, available at anytime. This free of charge “teaser” provides access to remote content by 1) setting up a call to a voice server or 2) sending an SMS or 3) opening a Mobile Internet session at a dedicated URL.Smart Card Web Server Case 2

Use Case 2: The Content Store
In this scenario, the mix between local and remote content is optimized to favor online purchasing of music or other multimedia content. The OMA SCWS Content Store provides a local catalog of content with a rich display. The end-user can preview and sample content before purchasing. Operators can remotely update the Content Store thanks to the OMA SCWS remote administration protocol. This allows the periodic promotion of new content or a specific promotion, such as the ten most downloaded files of the week.

Use Case 3: The Helpdesk
OMA SCWS can be used to display a helpdesk on the browser with local content, allowing information about handset usage and configuration, as well as operator services that can be integrated. This benefits the end-user, offering an off-line help service that is always available, even when roaming or out of range. Because of the automated interface, OMA SCWS reduces call center costs, increases service adoption and data usage by keeping the end-user informed of new choices, services and features.Smart Card Web Server Case 3

Use Case 4: Rich User InterfaceSmart Card Web Server Case 4
OMA SCWS offers a rich graphical user interface to mobile operators’ existing services, such as TV-voting and horoscope content; or (U)SIM applications such as phonebook synchronization, m-banking, Instant Messaging, and mobile Near Field Communications services (m-NFC).

Example 1: Wallet display for m-NFC services: OMA SCWS enables a contactless mobile payment application residing on the Smart Card to have a user-friendly interface. This allows activation/deactivation or configuration of the application. This allows for all elements composing the m-NFC services to be deployed inside the Smart Card, ensuring service portability and interoperability across all handsets.

Example 2: TV-voting services: The ability to display local content on the Smart Card allows the OMA SCWS User Interface to provide interactive TV-voting services by displaying pictures or clips concerning each candidate and weekly updates after nominations.

Example 3 with the (U)SIM Toolkit based services: The OMA SCWS User Interface allows the reuse of existing (U)SIM Toolkit based services with an enhanced graphical user interface.

Background—OMA Architecture Smart Card Technology (ARC-SCT) Working Group

OMA ARC-SCT Working Group provides the primary source of expertise within the OMA on issues related to Smart Cards and other secure hardware tokens using similar technology.

Some examples in addition to the SCWS Enabler: ARC-SCT has worked in the past on the On Board Key Generation (OBKG) Enabler including the WIM (Wireless Identity Module) Application specification.

More recently, ARC-SCT has contributed to the UICC related features of the OMA Open Connection Manager API Enabler.
