Protecting BlackBerry device data in transit

From the time that the user sends data (for example, an email message) from the BlackBerry® device until the BlackBerry®

Professional Software receives the data, and from the time that the BlackBerry Professional Software receives and forwards

data to the user until the user receives the data on the BlackBerry device, standard BlackBerry encryption uses a symmetric

algorithm to protect the data.

By default, the BlackBerry Professional Software uses both the Triple Data Encryption Standard (Triple DES or 3DES) and

the Advanced Encryption Standard (AES) algorithms to encrypt all communication with BlackBerry devices.

Encryption algorithm Description Notes

Triple DES enables the use of the Triple DES

algorithm to encrypt and decrypt all data

communication between the BlackBerry

Professional Software and all BlackBerry

devices

provides Triple DES encryption only on

BlackBerry devices

AES enables the use of the AES algorithm to

encrypt and decrypt all data

communication between the BlackBerry

Professional Software and all BlackBerry

devices

• uses a longer encryption key,

which is designed to provide a

better combination of security

and performance than Triple DES

• helps to protect user data and

encryption keys from traditional

and side-channel attacks

Triple DES and AES provides Triple DES encryption on

BlackBerry device that do not support AES

(BlackBerry devices that run BlackBerry®

Device Software versions earlier than 4.0)

provides the default encryption

method

Change the encryption type

1. In the BlackBerry® Manager, click the Home tab.
