Configuring the key information for the consumer binding on the application level

Configuring the key information for the consumer binding on the application level

Configure the key locators and the token consumers that are referenced by the Key locator reference and the Token reference fields within the key information panel.
This task provides the steps that are needed for configuring the key information for the request consumer (server side) and the response consumer (client side) bindings at the application level. The key information on the consumer side is used for specifying the information about the key, which is used for validating the digital signature in the received message or for decrypting the encrypted parts of the message. Complete the following steps to configure the key information for consumer binding on the application level.
Locate the key information configuration panel in the administrative console.

Click Applications > Enterprise applications > application_name.
Under Related Items, click EJB Modules or Web Modules > URI_name.
Under Additional properties, you can access the key information for the request consumer and response consumer bindings.

For the request consumer (receiver) binding, click Web services: Server security bindings. Under request consumer (receiver) binding, click Edit custom.

For the response consumer (receiver) binding, click Web services: Client security bindings. Under response consumer (receiver) binding, click Edit custom.

Under Required properties, click Key information.
Click New to create a key information configuration, click Delete and select the box next to the configuration to delete an existing configuration, or click the name of an existing key information configuration to edit its settings. If you are creating a new configuration, enter a name in the Key information name field. For example, you might specify con_signkeyinfo.
Select a key information type from the Key information type field. The key information types specify different mechanisms for referencing security tokens using the <wsse:SecurityTokenReference> element within the <ds:KeyInfo> element. WebSphere® Application Server supports the following key information types:
Key identifier
The security token is referenced using an opaque value that uniquely identifies the token. The algorithm that is used for generating the <KeyIdentifier> element value depends upon the token type. For example, you can use the identifier for the public keys that are defined in the Internet Engineering Task Force (IETF) Request for Comment (RFC) 3280. The following <KeyInfo> element is generated in the Simple Object Access Protocol (SOAP) message for this key information type:
<ds:KeyInfo xmlns:ds="http://www.w3.org/2000/09/xmldsig#">
   <wsse:SecurityTokenReference>
      <wsse:KeyIdentifier ValueType="http://docs.oasis-open.org/wss/2004/01
      /oasis-200401-wss-x509-token-profile-1.0#X509v3SubjectKeyIdentifier">/62wXO...
      </wsse:KeyIdentifier>
   </wsse:SecurityTokenReference>
</ds:KeyInfo>
Key name
The security token is referenced using a name that matches an identity assertion within the token. It is recommended that you do not use this key type as it might result in multiple security tokens that match the specified name. The following <KeyInfo> element is generated in the SOAP message for this key information type:
<ds:KeyInfo>
   <ds:KeyName>CN=Group1</ds:KeyName>
</ds:KeyInfo>
In general, use a key name when you use a Key-Hashing Message Authentication Code (HMAC) digital signature algorithm, such as http://www.w3.org/2000/09/xmldsig#hmac-sha1.
Security token reference
The security token is directly referenced using Universal Resource Identifiers (URIs). The following <KeyInfo> element is generated in the SOAP message for this key information type:
<ds:KeyInfo>
   <wsse:SecurityTokenReference>
      <wsse:Reference URI='#SomeCert'
       ValueType="http://docs.oasis-open.org/wss/2004/01/
          oasis-200401-wss-x509-token-profile-1.0#X509v3" />
   </wsse:SecurityTokenReference>
</ds:KeyInfo> 
Attention: As stated in the Web services Interoperability Organization (WS-I) Basic Security Profile Version 1 draft and shown in the previous example, the wsse:Reference element in a SECURE_ENVELOPE must have a ValueType attribute.
Embedded token
The security token is directly embedded within the <SecurityTokenReference> element. The following <KeyInfo> element is generated in the SOAP message for this key information type:
<ds:KeyInfo>
   <wsse:SecurityTokenReference>
      <wsse:Embedded wsu:Id=”tok1” />
         …
      </wsse:Embedded>
   </wsse:SecurityTokenReference>
</ds:KeyInfo>
X509 issuer name and issuer serial
The security token is referenced by an issuer name and an issuer serial number of an X.509 certificate. The following <KeyInfo> element is generated in the SOAP message for this key information type:
<ds:KeyInfo>
   <wsse:SecurityTokenReference>
     <ds:X509Data>
        <ds:X509IssuerSerial>
           <ds:X509IssuerName>CN=Jones, O=IBM, C=US</ds:X509IssuerName>
           <ds:X509SerialNumber>1040152879</ds:X509SerialNumber>
        </ds:X509IssuerSerial>
     </ds:X509Data>
   </wsse:SecurityTokenReference>
</ds:KeyInfo>
Each type of key information is described in the Web Services Security: SOAP Message Security 1.0 (WS-Security 2004) OASIS standard, which is located at: http://www.oasis-open.org/home/index.php under Web services security.
Select a key locator reference from the Key locator reference field. The value of this field is a reference to a key locator that WAS uses to locate the keys that are used for digital signature and encryption. Before you can select a key locator, configure a key locator. For more information on configuring a key locator, see Configuring the key locator for the consumer binding on the application level.

Select a token reference from the Token reference field. The token reference specifies a reference to a token consumer that is used for processing the security token in the message. However, WAS requires this field only when you select Security token reference or Embedded token in the Key information type field. Before specifying a token reference, configure a token consumer. For more information on configuring a token consumer, see Configuring token consumer on the application level.
Select (none) if a token consumer is not required for this key information configuration.

Click OK and Save to save this configuration.
You have configured the key information for the generator binding at the application level
If you have not configured the key information for the generator binding. You must specify a similar key information configuration for the generator. After you configure the key information for both the consumer and the generator, configure the signing information or encryption information, which references the key information that is specified in this key information task.
