Protecting the BlackBerry Infrastructure connections 30
Step Action Description
3 The BlackBerry Enterprise
Server sends a challenge string
to the BlackBerry
Infrastructure.
When the BlackBerry Enterprise Server receives the BlackBerry
Infrastructure challenge string, it sends a challenge string to the
BlackBerry Infrastructure.
4 The BlackBerry Infrastructure
sends a challenge response to
the BlackBerry Enterprise
Server.
The BlackBerry Infrastructure hashes the BlackBerry Enterprise
Server challenge string with the SRP authentication key, a 20-byte
shared secret encryption key, using the keyed HMAC with SHA1.
The BlackBerry Infrastructure sends the resulting 20-byte value
back to the BlackBerry Enterprise Server.
5 The BlackBerry Enterprise
Server sends a challenge
response to the BlackBerry
Infrastructure.
The BlackBerry Enterprise Server responds to the BlackBerry
Infrastructure challenge string by hashing the challenge with the
shared SRP authentication key.
6 The BlackBerry Infrastructure
sends an acceptance to the
BlackBerry Enterprise Server.
When the BlackBerry Infrastructure accepts the challenge
response, it sends a final confirmation to the BlackBerry Enterprise
Server to complete the authentication process and set up an
authenticated SRP connection between the BlackBerry
Infrastructure and the BlackBerry Enterprise Server. If the
BlackBerry Infrastructure rejects the response, the connection fails
and SRP ends the authentication session.
BlackBerry Router protocol authentication
The BlackBerry Router is designed to bypass the SRP authenticated connection to the BlackBerry Infrastructure
to route data to BlackBerry devices that are connected to the BlackBerry Device Manager through a physical
connection to a desktop computer. Data between the BlackBerry devices and the BlackBerry Router is
compressed and encrypted.
You can install the BlackBerry Router on a remote computer to route data traffic between the BlackBerry
Infrastructure and one or more BlackBerry Enterprise Servers. The BlackBerry device must authenticate itself to
the BlackBerry Enterprise Server to prove that it knows the master encryption key before the BlackBerry Router
sends data to the BlackBerry device.
When the BlackBerry Router protocol authentication is successful, the BlackBerry device sends data to the
BlackBerry Router through the BlackBerry Device Manager, and the BlackBerry Router sends data to the
BlackBerry device through the BlackBerry Device Manager. When the user disconnects the BlackBerry device
from the desktop computer or closes the BlackBerry Device Manager, the wireless data flow over the SRP
connection is restored.

1 A user physically connects a BlackBerry
device to a desktop computer.
The user connects the BlackBerry device to a desktop
computer that is running the BlackBerry Device
Manager.
