<h5><a name="wsseccfadigicert"></a>Configure Web services digital signature authentication</h5>
<p>With digital signature authentication, the client generates a security token, based on a digital signature, and embeds it in the SOAP message. For more information about digital signatures, see <a href="wsseccfxmlsign.htm">XML digital signature</a>.</p>
<p>The server then extracts the token and validates it by using a Java Authentication and Authorization Service (JAAS) login module. For more information, see <a href="wssecsignauth.htm">Digital signature authentication method</a>.</p>
<p><strong>Note:</strong> To use the digital signature authentication mechanism for Web services, you must configure WebSphere global security. For more information, see <a href="../sec/seccglo.htm">Configure global security</a> in the <em>Security</em> topic.</p>
<p>Perform the following steps to configure the digital signature authentication mechanism for your Web service:</p>
