*Description*
31
The interface can be used to start the eID application.
32
33
The parameters ifdName, contextHandle, slotHandle and cardType address a particular eCard, or a type of card.
34
There are three meaningful combinations of the optional parameters:
35
* _none_
36
 Use the fist nPa available. Display a "Please insert nPa" dialog if needed. This is the behaviour of the AusweisApp.
37 13 Tobias Wich
 In other words the lack of the cardType parameter sets it to the default value @http://bsi.bund.de/cif/npa.xml@, and thus the next rule becomes effective.
38 8 Tobias Wich
* _cardType_
39
 Use the fist card of the specified type which is available. Display a "Please insert <cardType>" dialog if needed.
40 13 Tobias Wich
 A special case must be made when software certificates (cardType=@http://openecard.org/cif/soft-credential@) are used. In that case no dialog is shown, when there is no certificate. Instead an error is produced.
41 8 Tobias Wich
* _ifdName_, _contextHandle_, _slotHandle_
42
 Use exactly the card matching the parameters.
43 13 Tobias Wich
  cardType is requested from the selected card directly. If there is no such card, an error is produced.

*Notes*

<pre>
49
TODO
50
* What happens if the Client Activator cannot start an application?
51
* What happens if the Client Activator cannot fetch a TC Token from the given TCTokenURL? Should that result in a 400 or 404?
52
</pre>
53
54 11 Tobias Wich
During the processing of the activation, a TCToken is fetched from a remote server.
55
The TCToken is defined as follows:
56
<pre><code class="xml">
57
<element name="TCToken" type="TCTokenType" />
58 1 Moritz Horsch
59 11 Tobias Wich
<complexType name="TCTokenType">

63

64
    <element name="Binding" type="anyURI" maxOccurs="1" minOccurs="0"/>
65
    <element name="PathSecurity-Protocol" type="anyURI" />
66
    <element name="PathSecurity-Parameter" maxOccurs="1" minOccurs="0">
67
      <complexType>

77 11 Tobias Wich
The contents of the elements are defined as follows:
78
* ServerAddress
79
 Must contain a https-URL which shall be used by the eCA to connect to the authentication server.
80
* SessionIdentifier
81
 Must contain a unique identifier of the current authentication session.
82
* RefreshAddress
83
 Must be a https-URL. The eCA redirects the browser to this URL (or the URL retrieved by following redirects starting from this URL) after conclusion of the online authentication.
84
* Binding
85
 May be used to indicate that an authentication protocol according to [ISO24727-3] is to be performed over the session between eCA and the authentication server.
86
 Currently the following values are defined:
87
** @urn:liberty:paos:2006-08@
88
* PathSecurity-Protocol
89
 This element specifies the security protocol, which is to be used for securing the connection between eCA and AS.
90
 Currently the following values are defined:
91 12 Tobias Wich
** @urn:ietf:rfc:4346@
92 11 Tobias Wich
   TLS according to [RFC4346].
93
** @urn:ietf:rfc:4279@
94
   TLS-PSK according to [RFC4279].
95
** @urn:ietf:rfc:5487@
96
   TLS-PSK with a cipher suite according to [RFC5487].
97
* PathSecurity-Parameter
98
   Must be present to supply path security parameters such as PSK values.
99
100
The following changes are made to the token type defined in [eCard-7]:
101
* Binding is optional to use solely the transport protocol for authentication.
102 12 Tobias Wich
* PathSecurity-Protocol has an additional value. (@urn:ietf:rfc:4346@)
103 11 Tobias Wich
* PathSecurity-Parameter is optional because of the additional default TLS Protocol.
