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.
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 security that requires operator intervention to
avoid having the connection time out and fail.
Authorization is limited to:
Yes, you may connect (click the balloon to proceed).
No, you may not connect (ignore the balloon prompt and the
connection will fail).

Bluetooth Device Identity

Every Bluetooth device has a unique Bluetooth Device Address (BDA)
assigned to it during the manufacturing process. This address cannot be
changed by the end-user.
A device's BDA is usually
00:40:F4:39:57:6D is a valid BDA.
Each Bluetooth device also has an operator-configurable, user-friendly name
to help distinguish it from other devices. The user-friendly name may be up
to 99 alphanumeric characters in length and may contain spaces. My
Personal Computer is a valid user-friendly name.

Encryption

Encryption translates data into an unreadable format using a secret key or
password. Decrypting the data requires the same key or password that was
used to encrypt it.

Link Key

A unique, internally generated, access code based on a passkey, the Bluetooth
Device Address and an internally generated random number. Link keys are
generated automatically when devices Pair.
After a link key is generated, manual entry of the passkey is not required.

Pairing Devices

Pairing allows you to avoid entering access information each time a
connection is attempted. Paired devices share a unique link key, which they
exchange each time they connect.
Paired devices remain paired even when
One of the devices is not on
