In this scenario, the Aster Database allows connections from clients that have no certificate. The server provides a self-signed certificate to the client at the time of authentication. The certificate on the queen will be signed by the server itself, as opposed to by a CA (certification authority). In such a configuration, any client can establish an SSL-secured connection, provided the user authenticates successfully with Aster Database. Communications from the client to Aster Database (for example, queries submitted to the database) are SSL encrypted, and query results travel in the clear.
