SECURITY
Introduction
Each service that the server provides can be configured to require the Secure Connection
setting, that means of,
Authorization: the server operator must acknowledge all connection attempts
before a connection is established.
Authentication: the server requires a Personal Identification Number code (PIN,
also referred to as a “passkey”) or a Link Key before a connection is established.
Encryption: all data sent between the Bluetooth client and Bluetooth server is
encrypted. The encryption key is based on the Authentication Link Key. Encryption
requires that Authentication be enabled.
The Secure Connection is enabled by default.
Authentication
Authentication is used to verify identity. It requires a passkey or Link Key from the remote device.
When a remote device attempts access to a unit, a visual and/or audio warning notifies the local
operator of the invitation.
The local operator can open a dialog box that provides:
1. The user-friendly name of the device attempting access.
2. A place for the local operator to enter a Bluetooth passkey.
The operator of the remote system must then enter the identical passkey. If no passkey is
supplied or if the notification is ignored after a preset timeout, access will be denied. In cases
wherein devices are paired, those devices automatically exchange a Link Key and authentication
is carried out without operator intervention.
Authorization
Authorization is yes-or-no security. When a remote device attempts to connect, a visual and/or
audio warning alerts the server operator.
The server operator then responds by clicking the Bluetooth Tray icon in the Windows system
tray to open a dialog box that displays:
1. The user-friendly name of the device attempting to connect.
2. The local service to which the remote device is attempting to connect.
The server operator may grant or deny access to the service by clicking an on-screen button. If
the server operator ignores the Authorization notification after a preset timeout, access will be
denied.
