Project-Structure¶

The overall project structure has been derived from the high level design of the Open eCard App (see [[Sicherheit 2012 submission) and is depicted in the following figure:

Modules¶

The following modules are derived from the high level project structure.
Information about the architecture, data structures and other things can be found in the respective links.

wsdef¶

Contains web service definitions (.xsd, .wsdl) and related utilities.

• class-list-plugin
• wsdef-client

common¶

Contains common utilities and helper classes.

crypto¶

Contains basic crypto modules.

• bouncycastle
  Relocated bouncycastle classes (moved from org.bouncycastle to org.openecard.bouncycastle) with some patches regarding TLS-PSK.
• crypto-common
  Other crypto related code. E.g. ASN.1 classes for EAC and CVC.

saml¶

Contains the functionality for [[SAML-ECP]].

esign¶

Contains signature-related functionality.

transport¶

Contains modules related to the transport of messages.

• dispatcher
• paos
• tls
  The TLS design can be found here.

gui¶

Contains user interfaces (User Consent) for the different platforms.

• gui-common
  Data structure definitions and common GUI execution code.
• swing
  Swing based User Consent implementation.
• android
  Android UI based User Consent implementation.

ifd¶

Contains the interface device (IFD) components for the different platforms. The following figure provides an overview of the relationship between the different ifd modules:

• ifd-common
  Code and data structures common to core and protocol modules.

• protocols
  Contains IFD-related trusted channel protocols, which can be used with EstablishChannel. Currently the following protocols are supported:
  • pace
    Password Authenticated Connection Establishment [[PACE]]

• scio-backend
  Provides an implementation of [[javax.smartcardio]] for different platforms.
  • oma
    Maps [[javax.smartcardio]] to the [[Transport API within the Open Mobile API]].
  • android-nfc
    Maps [[javax.smartcardio]] to [[android.nfc]].
  • android-scio
    Maps [[javax.smartcardio]] to a native PCSC implementation [[pcsclite]] compiled for Android.
    More information can be found here.
  • pcsc
    Is necessary to embed the java default implementation of the SmartcardIO into the scio-backend context.

• ifd-core
  Implements the IFD-API including the mapping to [[javax.smartcardio]].

sal¶

Contains the service access layer (SAL) components.

• sal-common
• protocols
  • eac
  • crypto-lite
• tiny-sal

recognition¶

Features CardInfo-based card type recognition. This module also bundles CardInfo files for the recognisable cards.

event-manager¶

Provides an easy to use interface for IFD related events.

browser¶

Contains components for the integration of the Open eCard App into popular browsers.

• object-handler
• pkcs11

• tls-channel-binding

control-interface¶

This module is used to activate the client and authenticate against a server.
The eCard-API Framework part 7 defines the TCToken-Interface to trigger the activation.
More sophisticated activation scenarios need the possibility to request information about the App and available token. The Status-Interface extends the TCToken-Interface respectively.

client¶

Contains modules for the different forms of the Open eCard App.

• applet
• richclient
• android
