Secure web services for version 5.x applications using signature authentication

WebSphere Application Server provides several different methods to secure the web services. XML digital signature is one of these methods.

There is an important distinction between v5.x and v6 and later applications. The information in this article supports v5.x applications only used with WAS v6.0.x and later. The information does not apply to v6 and later applications.

We can secure the web services using any of the following methods:

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:

  1. Secure the client for signature authentication.

    1. Configure the client for signature authentication: specifying the method.
    2. Configure the client for signature authentication: collecting the authentication information.

  2. Secure the server for signature authentication.

    1. Configure the server to support signature authentication.
    2. Configure the server to validate signature authentication information.
