Secure Messaging

In the CIM RMI protocol, each request from the client to the WBEM server contains a message authenticator that is constructed from the data parameters in the message. A one-way digest is also created with a session key established during the authentication exchange.

The WBEM server verifies this message authenticator, which guarantees that the request came from the same client that was authenticated and that the message was not modified or replayed during its communications to the server.

If the message was modified, replayed, or created by a source that was not the original client, the WBEM server returns a CIM security exception that contains the CHECKSUM_ERROR error. The WBEM server also writes a log message to the WBEM log.
