Open eCard

h1. Project-Structure

The overall project structure has been derived from the high level design of the Open eCard App (see [["Sicherheit 2012 submission":https://redmine.vserver-001.urospace.de/attachments/14/Open-eCard-App-2011-12-05.pdf]]) and is depicted in the following figure:

h1. 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.

h2. wsdef

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

* *class-list-plugin*

* *wsdef-client*

h2. common

Contains common utilities and helper classes.

h2. 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.

h2. saml

Contains the functionality for [["SAML-ECP":http://www.oasis-open.org/committees/download.php/41209/sstc-saml-ecp-v2.0-wd02.pdf]].

h2. esign

Contains signature-related functionality.

h2. transport

Contains modules related to the transport of messages.

* *dispatcher*

* *paos*

* *tls*

  The TLS design can be found [[TLS-Design|here]].

h2. 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.

h2. 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-Module-Structure_656x280.png!

* *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":https://www.bsi.bund.de/ContentBSI/Publikationen/TechnischeRichtlinien/tr03110/index_htm.html]]

* *scio-backend*

  Provides an implementation of [["javax.smartcardio":http://docs.oracle.com/javase/6/docs/jre/api/security/smartcardio/spec/javax/smartcardio/package-summary.html]] for different platforms.

** *oma*

   Maps [["javax.smartcardio":http://docs.oracle.com/javase/6/docs/jre/api/security/smartcardio/spec/javax/smartcardio/package-summary.html]] to the [["Transport API within the Open Mobile API":http://www.simalliance.org/en?t=/documentManager/sfdoc.file.supply&e=UTF-8&i=1185787014303&l=0&fileID=1322061907922]].

** *android-nfc*

   Maps [["javax.smartcardio":http://docs.oracle.com/javase/6/docs/jre/api/security/smartcardio/spec/javax/smartcardio/package-summary.html]] to [["android.nfc":http://developer.android.com/reference/android/nfc/package-summary.html]].

** *android-scio*

   Maps [["javax.smartcardio":http://docs.oracle.com/javase/6/docs/jre/api/security/smartcardio/spec/javax/smartcardio/package-summary.html]] to a native PCSC implementation [["pcsclite":http://pcsclite.alioth.debian.org]] compiled for Android.

   More information can be found [[Android-PCSC|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":http://docs.oracle.com/javase/6/docs/jre/api/security/smartcardio/spec/javax/smartcardio/package-summary.html]].

h2. sal

Contains the service access layer (SAL) components.

* *sal-common*

* *protocols*

** *eac*

** *crypto-lite*

* *tiny-sal*

h2. recognition

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

h2. event-manager

Provides an easy to use interface for IFD related events.

h2. browser

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

* *object-handler*

* *pkcs11*

!TLS-module-structure_667x404.5.png!

* *tls-channel-binding*

h2. control-interface

This module is used to activate the client and authenticate against a server.

The eCard-API Framework part 7 defines the [[Control_Interface#Activation|TCToken-Interface]] to trigger the activation.

More sophisticated activation scenarios need the possibility to request information about the App and available token. The [[Control_Interface#GetStatus1|Status-Interface]] extends the TCToken-Interface respectively.

h2. client 

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

* *applet*

* *android*

* *j2me*
