33. Security
• Pin-code – authentication with a single-use password.The trust relationship
is persistent, as it is in Bluetooth, for instance. Once authenticated, you'll be
able to make secure calls between the apps.
• Log on – username and password, required every time the apps connect.
• Certi
fi
cate-based – RSA public key authentication and X.509 certi
fi
cate
chain.The trust relationship lasts as long as the certi
fi
cate remains valid.
