Extending messaging security to a BlackBerry device

If your organization's messaging environment supports highly secure messaging technology such as PGP® encryption or S/MIME

encryption, you can configure the BlackBerry® Enterprise Solution to encrypt a message using PGP encryption or S/MIME

encryption so that the message remains encrypted when the BlackBerry® Enterprise Server forwards the message to the email

applications of recipients. To extend messaging security, the sender and recipient must install highly secure messaging technology

on the computers that host the email applications and on their BlackBerry devices, and you must configure the BlackBerry devices

to use the highly secure messaging technology.

Extending messaging security using PGP encryption

You can extend messaging security for the BlackBerry® Enterprise Solution and permit a BlackBerry device user to send and

receive PGP® protected email messages and PGP protected PIN messages on a BlackBerry device. The BlackBerry Enterprise

Solution supports the OpenPGP format and PGP/MIME format on the BlackBerry device.

To extend messaging security, you must instruct the BlackBerry device user to install the PGP® Support Package for BlackBerry®

smartphones on the BlackBerry device and to transfer the PGP private key of the BlackBerry device user to the BlackBerry device.

The BlackBerry device user can use the PGP private key to digitally sign, encrypt, and send PGP protected messages from the

BlackBerry device. If a BlackBerry device user does not install the PGP Support Package for BlackBerry smartphones, the

BlackBerry device receives PGP protected messages as unreadable ciphertext.

To require the BlackBerry device user to use PGP encryption when forwarding or replying to messages, you can configure the

PGP Force Digital Signature IT policy rule and the PGP Force Encrypted Messages IT policy rule.

The PGP Support Package for BlackBerry smartphones is designed to support encoding and decoding Unicode messages and

permits PGP encryption using keys or passwords. The PGP Support Package for BlackBerry smartphones permits the BlackBerry

device to encrypt PGP protected email messages or PGP protected PIN messages using a password that the sender and recipient

both know .

For more information about the OpenPGP format, see RFC 2440. For more information about the PGP/MIME format, see RFC 3156.

For more information about the PGP Support Package for BlackBerry smartphones, see the PGP Support Package for BlackBerry

Devices Security Technical Overview.
