2 - 6 RFD8500 User Guide
Security
The current Bluetooth specification defines security at the link level. Application-level security is also available
via a ZETI interface password. This allows application developers to define security mechanisms tailored to
their specific need. Link-level security occurs between devices, not users, while application-level security can
be enabled globally. The Bluetooth specification defines security algorithms and procedures required to
authenticate devices, and if needed, encrypt the data flowing on the link between the devices. Device
authentication is a mandatory feature of Bluetooth while link encryption is optional. The RFD8500 Bluetooth
interface uses authentication and security by default, and is compatible with devices supporting Bluetooth v2.1
and later.
RFD8500 uses the 'just works' methods defined under the Secure Simple Pairing (SSP) framework. Thus, no
personal identification number (PIN) is required to pair.
Recommendations are:
•
Perform pairing in a secure environment
•
Implement application-level security.
The RFD8500 supports the following Bluetooth services:
•
Bluetooth v2.1 devices and later.
