PC/SC Applications and New Developments Boris Balacheff Member of PC/SC Technical Workgroup CTST 2000 Miami

2 PC/SC Revision 1.0 Limitations Emergence of Multi-application smartcards finds a lack of support in Revision 1.0 (I.e. Windows for Smartcards, JavaCards…): It is not possible to manage dynamically the off-card components that are used to interact with on-card applications Smartcard reader support is not up-to-date with current reader technology developments No support for synchronous and contactless cards

CTST 2000 Miami3 Multi-Application Cards Currently, Service Providers are mapped to a specific card-type (using ATR) in the Resource Manager database With multi-application cards, the card-type does not reflect the cards functionality/applications Need for a flexible and dynamic mechanism to update Service Provider information on the PC platform along with on-card applications changes

CTST 2000 Miami4 Multi-Application Cards (cont.) It is not enough that the PC/SC Resource Manager can only recognise a smartcard based on manufacturer-specific ATR information To be able to dynamically assign Services Providers, information describing the card must be held on the card Need for a card recognition mechanism that is more flexible, in order to reflect what is on the card dynamically

CTST 2000 Miami5 Enhanced Smartcard Readers Revision 1.0 only supports readers with basic APDU communication capabilities Reader technologies with extended capabilities become widespread (pinpads, displays, multi-slot, SecurePin, biometrics…) Need to allow interoperability between cards and PC applications that use these new reader capabilities

CTST 2000 Miami6 Other Card Technologies Contactless cards are a growing market Synchronous cards are already used by many applications Need to provide some support to allow the same interfaces and look-and-feel as asynchronous cards, at the PC application level

CTST 2000 Miami7 Introducing PC/SC Revision 2.0 Revision 2.0 of PC/SC aims at addressing these limitations. It does this by introducing the following: A New card recognition mechanism A Dynamic Service Provider Assignment mechanism A Mechanism for enhanced smartcard reader support Support for contactless and synchronous cards
