Pairing the Reader to the Mobile

Device

Before you can operate the reader with the mobile device, you must pair the

devices.

About Bluetooth Security

Bluetooth communication between the mobile device and the reader is

conducted over a locked down Bluetooth encrypted link, which is further

encrypted with an Advanced Encryption Standard (AES) AES-256 session

key. The session key is passed between the mobile device and the reader

using Rivest, Shamir, and Adleman (RSA) encryption and two-factor

authentication.

After the reader is paired with the mobile device, it is not discoverable and can

only be connected with the paired mobile device. The only way to force the

reader into a discoverable state is to perform another pairing operation with a

wired USB communication. All Bluetooth communications are forced to use

Bluetooth encryption.

During the USB-wired pairing operation, public 1024-bit RSA keys are

generated and exchanged between the mobile device and the reader. When a

Bluetooth session is started, the mobile device and the reader perform an RSA

encrypted two-way challenge and response to authenticate each other and

then share an AES-256 session key using RSA encryption. The shared AES-

256 session key is used to encrypt sensitive data being sent between the

mobile device and the reader.
