from an activation password to establish a shared master encryption key that enables strong authentication

between them.

After the BlackBerry device successfully activates on the BlackBerry Enterprise Server, the BlackBerry device no

longer requires the activation password. The user (or another user) cannot reuse that password to activate

another BlackBerry device.

Note: A WLAN implementation of the BlackBerry Enterprise Solution does not support wireless enterprise

activation.

Wireless enterprise activation authentication process

Step Action Description

1 A user initiates the wireless enterprise

activation process.

The user opens the enterprise activation program on the

BlackBerry device and types their corporate email

address and the activation password that you

communicated to them.

2 The BlackBerry device sends an activation

request to the BlackBerry Infrastructure.

The BlackBerry device sends an activation request to

the BlackBerry Infrastructure using standard BlackBerry

protocols. The BlackBerry Infrastructure uses SMTP to

send an activation message to the user’s corporate

email account. This activation message contains

BlackBerry device routing information and public keys.

3 The BlackBerry Enterprise Server sends an

activation response to the BlackBerry

device.

The BlackBerry Enterprise Server sends the BlackBerry

device an activation response that contains BlackBerry

Enterprise Server routing information and public keys.

4 The BlackBerry Enterprise Server and the

BlackBerry device establish and verify the

shared master encryption key.

The BlackBerry Enterprise Server and the BlackBerry

device use the initial key establishment protocol to

establish a master encryption key. The BlackBerry

Enterprise Server and the BlackBerry device verify the

master encryption key with each other. If the BlackBerry

Enterprise Server and the BlackBerry device mutually

confirm the correct master encryption key, the

activation proceeds, and the BlackBerry Enterprise

Server and the BlackBerry device use the master

encryption key to encrypt further communication

between them.

5 The BlackBerry Enterprise Server sends

service books to the BlackBerry device.

The BlackBerry Enterprise Server sends the appropriate

service books to the BlackBerry device. The user can

now send messages from and receive messages on the

BlackBerry device.

6 The BlackBerry Enterprise Server sends

data to the BlackBerry device.

If wireless PIM synchronization and wireless backup is

enabled for the user, the BlackBerry Enterprise Server

sends the following data to the user’s BlackBerry

device:

• calendar entries

• contacts, tasks, and memos

• existing BlackBerry device options (if applicable)

that the BlackBerry device backed up using

automatic wireless backup.

See the BlackBerry Wireless Enterprise Activation Technical Overview for more information.
