For security model B, the local Adaptive Server gets a credential from the security mechanism and uses the credential to establish a secure physical connection with the remote Adaptive Server. With this model, you can use one or more of these security services:
Mutual authentication – the local server authenticates the remote server by retrieving the credential of the remote server and verifying it with the security mechanism. With this service, the credentials of both servers are authenticated and verified.
Message confidentiality via encryption – messages are encrypted when sent to the remote server, and results from the remote server are encrypted.
Message integrity – messages between the servers are checked for tampering.
