Criteria Description

integrity The BlackBerry Enterprise Solution helps protect each message that a BlackBerry device

sends using one or more message keys. Designed to prevent a third party from decrypting

or altering the message data, the message keys consist of random data.

The BlackBerry Enterprise Solution is designed so that only the BlackBerry Enterprise

Server and a BlackBerry device know the value of a master encryption key, recognize the

format of a decrypted and decompressed message, and automatically reject a message

that is not encrypted with the correct master encryption key.

authenticity A BlackBerry device authenticates itself with the BlackBerry Enterprise Server to prove

that it knows the master encryption key before the BlackBerry Enterprise Server can send

data to the BlackBerry device.

Master encryption keys

The BlackBerry® Enterprise Server and the BlackBerry device each store a copy of the unique master encryption key of the

BlackBerry device.

When you activate a BlackBerry device over the wireless network, the BlackBerry Enterprise Server and BlackBerry device use an

authenticated link to communicate the value of the master encryption key.

For a user to send and receive messages on the BlackBerry device, the BlackBerry Enterprise Server and BlackBerry device must

store matching copies of the master encryption key of the BlackBerry device. If the stored keys do not match, the following actions

occur:

• BlackBerry Enterprise Server and BlackBerry device delete messages that they receive from each other because they cannot

decrypt them

• BlackBerry device requires the user to generate a new master encryption key

Standard BlackBerry encryption

The BlackBerry® Enterprise Solution uses a symmetric key encryption algorithm that is designed to protect data in transit between

a BlackBerry device and the BlackBerry® Enterprise Server. Standard BlackBerry encryption, which is designed to provide strong

security, helps protect data in transit to the BlackBerry Enterprise Server when message data is outside of the organization's

firewall.

Standard BlackBerry encryption is designed to encrypt messages that a BlackBerry device sends or that the BlackBerry Enterprise

Server forwards to the BlackBerry device. Standard BlackBerry encryption encrypts messages as follows:

• from the time the user sends an email message or PIN message from the BlackBerry device to the time when the BlackBerry

Enterprise Server receives the message
