BlackBerry Enterprise Solution data flow 1. message is compressed, encrypted using AES or Triple DES, and sent to wireless network. 2.Wireless network sends message to Internet through BlackBerry Infrastructure. 3. message reaches sender’s firewall and passes through outbound connection to BlackBerry Enterprise Server. 4.BlackBerry Enterprise Server decrypts, decompresses, and sends message to Outbox folder. © 2009 Research In Motion Limited AES Advanced Encryption Standard Triple DES Triple Data Encryption Standard

BlackBerry Enterprise Solution data flow 5. message travels across Internet as SMTP traffic to receiver’s firewall. 6.BlackBerry Enterprise Server monitors receiver’s mailbox, retrieves message, compresses and encrypts the first 2Kb of message, and queues it for delivery. 7.Receiver’s BlackBerry smartphone receives, decrypts, and decompresses message. © 2009 Research In Motion Limited SMTP Simple Mail Transfer Protocol

BlackBerry Internet Service BlackBerry Browser features: –BlackBerry Browser uses BlackBerry Internet Service as a gateway to the Internet and is hosted by the BlackBerry Infrastructure. –BlackBerry Internet Service differs from BlackBerry MDS as it does not require the BlackBerry Enterprise Server and is not used through the organization’s firewall. –BlackBerry Internet Service does not support Triple DES encryption and secure sites (HTTPs) are not available. © 2009 Research In Motion Limited

BlackBerry Internet Service –Communicates with the BlackBerry Infrastructure using HTTP over the RIM ® IPPP –Preprocesses and compresses HTML or XHTML content before sending it to the BlackBerry smartphone, which speeds up transfers –Sends processed content to the BlackBerry smartphone as it becomes available –Optimizes images for display on BlackBerry smartphone © 2009 Research In Motion Limited RIM Research in Motion IPPP IPPP Internet Protocol Proxy Protocol XHTML Extensible HyperText Markup Language

BlackBerry Internet Service –Processes and transmits images with content to help reduce network traffic –Transcodes specific content types for appropriate display on the BlackBerry smartphone –Permits BlackBerry smartphone users to associate their BlackBerry smartphones with an address in the blackberry.net domain –Permits BlackBerry smartphone users to associate up to ten work or personal accounts with a BlackBerry smartphone © 2009 Research In Motion Limited

BlackBerry Internet Service Permits BlackBerry smartphone users to: –Experience push delivery of messages –Access attachments and images wirelessly in popular formats –Access HTML and WAP web pages using the BlackBerry Internet Service Browsing service © 2009 Research In Motion Limited WAP Wireless Application Protocol

BlackBerry Internet Service –BlackBerry Infrastructure interacts with BlackBerry Internet Servers that are maintained by RIM® and administered by each wireless service provider. –Permits subscribers to resend service books to their BlackBerry smartphones and create message filters. –BlackBerry Internet Service compresses messages before sending them to the wireless network, but does not encrypt content. © 2009 Research In Motion Limited
