Encrypting data that the BlackBerry Enterprise Server and a device send to each other

To encrypt data that is in transit between the BlackBerry® Enterprise Server and a BlackBerry device in your organization, the BlackBerry® Enterprise Solution uses BlackBerry transport layer encryption. BlackBerry transport layer encryption is designed to encrypt data from the time that a device user sends a message from the device to when the BlackBerry Enterprise Server receives the message, and from the time that the BlackBerry Enterprise Server sends a message to when the device receives the message.

Before the device sends a message, it compresses and encrypts the message using the device transport key. When the BlackBerry Enterprise Server receives a message from the device, the BlackBerry Dispatcher decrypts the message using the device transport key, and then decompresses the message.
