WCF wsHttpBinding in SoapUI

I am trying to add a WCF service using wsHttpBindingin soapUI.

I use message protection and works with the testing client, but SoapUI returns

Security check error occurred for message

Here is the service configuration:

<wsHttpBinding>
   <binding name="wsHttpSecure">
      <security mode="Message">
         <message clientCredentialType="UserName" negotiateServiceCredential="true"    
                  establishSecurityContext="false" algorithmSuite="Default" />
      </security>
   </binding>
</wsHttpBinding>

Here http://www.soapui.org/SOAP-and-WSDL/applying-ws-security.html is a document, but they say that I need a .jks file. I only encoded the public key value generated by SvcUtil in the test client configuration file.
