How a BlackBerry Enterprise Server and the

BlackBerry Infrastructure authenticate with

each other

The BlackBerry Infrastructure and BlackBerry Enterprise Server must authenticate with each other before they can

transfer data. The BlackBerry Enterprise Server uses SRP to authenticate with and connect to the BlackBerry

Infrastructure.

SRP is a point-to-point protocol that runs over TCP/IP. The BlackBerry Enterprise Server uses SRP to contact the

BlackBerry Infrastructure and open a connection. When the BlackBerry Enterprise Server and BlackBerry Infrastructure

open a connection, they perform the following actions:

• authenticate with each other

• exchange configuration information

• send and receive data

The BlackBerry Enterprise Server and BlackBerry Infrastructure use the SRP authentication key when they authenticate

with each other. The SRP authentication key is a 20-byte encryption key that the

BlackBerry Enterprise Server and

BlackBerry Infrastructure share.

The BlackBerry Enterprise Server sends only outgoing traffic to a BlackBerry device using an authenticated connection to

the BlackBerry Infrastructure.
