Data flow: Activating

BBM Enterprise

on a device

Create a

BBM Enterprise

profile.

Review the

BBM Enterprise

activation email template and modify it if necessary.

Add a user to

BlackBerry UEM

as a local user account or using the account information retrieved from your company directory.

Assign the

BBM Enterprise

profile to a user.

BlackBerry UEM
pushes the assigned
BBM Enterprise
profile through the
BlackBerry Infrastructure
to
BBM Enterprise
.

Use one of the following options to provide the user with activation details:

Automatically generate a device activation password and send an email with activation instructions for the user.
Set a device activation password and communicate the username and password to the user directly or by email.
Don't set a device activation password and communicate the
BlackBerry UEM Self-Service
address to the user so that they can set their own activation password.

If provided, the user can click a link in the activation email to be taken directly to

BBM Enterprise

.

Establishes a connection to the

BlackBerry Infrastructure

Sends a request for activation information to the

BlackBerry Infrastructure

using an HTTP CONNECT call over port 443.

Verifies that the user is a valid, registered user.

Retrieves the

BlackBerry UEM

address for the user.

Sends the address to the

BlackBerry UEM Client

.

Establishes a connection with

BlackBerry UEM

.

Generates a shared symmetric key that is used to protect the CSR (certificate signing request) and responds to

BlackBerry UEM

using the activation password and EC-SPEKE.

Creates an encrypted CSR and HMAC as follows:

Generates a key pair for the certificate.
Creates a PKCS#10 CSR that includes the public key of the key pair.
Encrypts the CSR using the shared symmetric key and AES-256 in CBC mode with PKCS#5 padding.
Computes an HMAC of the encrypted CSR using SHA-256 and appends it to the CSR.
Sends the encrypted CSR and HMAC to BlackBerry UEM.

Verifies the HMAC of the encrypted CSR and decrypts the CSR using the shared symmetric key.

Retrieves the username, work space ID, and your organization’s name from the

BlackBerry UEM

database.

Packages a client certificate using the information it retrieved and the CSR that the device sent.

Signs the client certificate using the enterprise management root certificate.

Encrypts the client certificate, enterprise management root certificate, and the

BlackBerry UEM

URL using the shared symmetric key and AES-256 in CBC mode with PKCS#5 padding.

Computes an HMAC of the encrypted client certificate, enterprise management root certificate, and the

BlackBerry UEM

URL and appends it to the encrypted data.

Sends the encrypted data and HMAC to the device.

Verifies the HMAC.

Decrypts the data it received from

BlackBerry UEM

.

Stores the client certificate and the enterprise management root certificate encrypted in

BBM Enterprise

.

Sends the device information (if it is available) and

BBM Enterprise

software information to

BlackBerry UEM

.

The

BlackBerry UEM

Core assigns the

BBM Enterprise

device to a

BlackBerry UEM

instance in the domain.

Retrieves a SCEP profile from

BlackBerry UEM

. This profile is used to trigger an assisted SCEP procedure in order to obtain a device-specific certificate, which will be used to access

BlackBerry UEM

and servers that are providing

BBM Enterprise

services.

The

BBM Enterprise

snap-in returns a SCEP profile (default or configured).

The

BBM Enterprise

client performs an assisted SCEP operation against the

BlackBerry Enterprise Identity

service mediated by

BlackBerry UEM

.

The resulting certificate, specific to a

BBM Enterprise

device, is sent back to the

BBM Enterprise

client.
