Process flow: Receiving a message that is encrypted using IBM Lotus Notes

1. A user creates a message in IBM® Lotus Notes® with encryption turned on, and sends the message to a BlackBerry® device

user.

2. The user’s email application sends the IBM Lotus Notes encrypted message to the IBM® Lotus® Domino® messaging server.

3. The BlackBerry Messaging Agent checks the user's mailbox, detects the new message, and accesses the encrypted message

using IBM Lotus Domino APIs.

• If the BlackBerry Messaging Agent has the user's Notes ID password, the BlackBerry Messaging Agent decrypts the

message.

• If the BlackBerry Messaging Agent does not have the user's Notes ID password, the BlackBerry Messaging Agent does

not decrypt the message.

4. The BlackBerry Messaging Agent creates an entry in the BlackBerry state database and sends the first 2 KB of the message

to the BlackBerry Dispatcher.

5. The BlackBerry Dispatcher compresses the first 2 KB of the message, encrypts it with the master encryption key of the

BlackBerry device, and sends the encrypted data to the BlackBerry Router.

6. The BlackBerry Router sends the encrypted data to the wireless network over port 3101.

7. The wireless network verifies that the PIN belongs to a valid BlackBerry device that is registered with the wireless network,

and delivers the message to the BlackBerry device.

8. The BlackBerry device sends a delivery confirmation to the BlackBerry Messaging Agent.

The BlackBerry device decrypts and decompresses the message so that the user can view it, and notifies the user that the

message has arrived.

9. The message appears on the BlackBerry device in the message list with a padlock indicator beside the envelope icon. When

the user opens the message, one of the following scenarios occurs:

• The message appears.

• The message appears with a "More Available" message. To see more of the message, the user must type the Notes ID

password.

• The BlackBerry device caches the password until the user resets the BlackBerry device or changes the password.
