Security Introduction

Each service that the server provides can be configured to require:

•Authorization -The server operator must acknowledge all connection attempts before a connection is established.

•Authentication -The server requires a Personal Identification Number (PIN) code 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 default security setting for Authorization, Authentication and Encryption is disabled.

Devices can also be paired, a process that eliminates the need to enter a PIN code every time access is attempted.

Authentication

Authentication is used to verify identity; it requires a passkey or Link Key from the remote device. When a remote device attempts access a visual and/or audio warning notifies the local operator.

The local operator can open a dialog box that provides:

•The user-friendly name of the device attempting access

•The name of the local service that the remote device is attempting to access

•A place for the local operator to enter a passkey.

The operator of the remote system must enter the identical passkey or access is denied.

If the notification is ignored, access is denied after a preset timeout.

When devices are paired, those devices automatically exchange a Link Key and Authentication is carried out without operator intervention.

Authorization

Authorization is Yes or No, go-no-go security.

A visual and/or audio warning alerts the server operator that a remote device is attempting to connect.

The server operator responds by clicking the Bluetooth icon in the Windows system tray to open
