  • transmitting a get_authToken message from a Universal Discovery Description and Integration (UDDI) client to a UDDI server, the get_authToken message specified in a UDDI standard as a single interaction that does not include an explicit challenge-response request, the get_authToken message requesting authentication information from the server, the get_authToken message comprising user information with at least one error in the user information, the error provided by the UDDI client specifically to trigger a challenge-response exchange with the UDDI server to request the authentication information, the challenge-response exchange providing the security of multiple interactions with the UDDI server using a mechanism specified as a single interaction, the challenge-response exchange comprising;

    receiving a second message from the UDDI server in response to the get_authToken message, the second message comprising an error message and a nonce;

    encrypting the nonce;

    transmitting a second get_authToken message to the server in response to the second message, the second get_authToken message comprising non-erroneous and complete user information and the encrypted nonce; and
