Securing Web services for version 5.x applications using signature
authentication
WebSphere Application Server provides several different methods
to secure your Web services. XML digital signature is one of these methods.
There is an important distinction between Version
5.x and V6 and later applications. The information in this article
supports V5.x applications only that are used with WebSphere
Application Server V6.0.x and later. The information does not
apply to V6 and later applications.
You can secure your Web
services by using any of the following methods:
- XML digital signature
- XML encryption
- BasicAuth authentication
- Identity assertion authentication
- Signature authentication
- Pluggable token
Overview
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:
Procedure
- Secure the client for signature authentication.
- Configuring the client for signature authentication: specifying the
method.
- Configuring the client for signature authentication: collecting the
authentication information.
- Secure the server for signature authentication.
- Configuring the server to support signature authentication.
- Configuring the server to validate signature authentication information.
Results
After completing these steps, you have secured your Web services using
signature authentication.
