Secure Web services for version 5.x applications using signature authentication
WAS provides several different methods to secure the Web services. XML digital signature is one of these methods.
There is an important distinction between V 5.x and V6 and later applications. The information in this article supports V5.x applications only that are used with WAS V6.0.x and later. The information does not apply to V 6 and later applications. We can secure the Web services by using any of the following methods:
- XML digital signature
- XML encryption
- BasicAuth authentication
- Identity assertion authentication
- Signature authentication
- Pluggable token
With the signature authentication method, the request sender generates a signature security token using a callback handler. The security token returned by the callback handler is inserted in the SOAP message. The request receiver retrieves the Signature security token from the SOAP message and validates it using a Java Authentication and Authorization Service (JAAS) login module. To use signature authentication to secure Web services, complete the following tasks:
- Secure the client for signature authentication.
- Secure the server for signature authentication.
Results
After completing these steps, we have secured the Web services using signature authentication.
Set the client for signature authentication: specifying the method
Set the client for signature authentication: collecting the authentication information
Set the server to support signature authentication
Set the server to validate signature authentication information
