Bluetooth USB Adapter User Guide 

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 is Yes-or-No security that requires operator intervention to avoid having 
the connection time out and fail. Authorization is enabled automatically when Secure 
Connection is enabled, but it can be turned off on a service-by-service basis for each 
remote device. 
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). 

Every Bluetooth device has a unique Bluetooth Device Address (BDA) assigned to it 
during the manufacturing process. This address cannot be changed. 
The BDA is usually displayed in hexadecimal format; 00:30:4F:03:2E:9F is a valid 
BDA. 
Each Bluetooth device also has a configurable, user-friendly name to help distinguish 
it from other devices. The user-friendly name may be up to 99 alphanumeric charac-
ters in length and may contain spaces. My Personal Computer is a valid user-friendly 
name. 

Encrypting data translates it 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. 

A link key is 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 are paired. 
After a link key is generated, manual entry of the passkey is not required.
