BlackBerry Meets Australian Government's Stringent Security Requirements

The Defence Signals Directorate (DSD) of the Australian Government has approved the deployment of the BlackBerry(R) platform, developed by Research In Motion (RIM) (NASDAQ:RIMM) (TSX:RIM), for its secure wireless communications and information access capabilities. BlackBerry meets the Australian Government's strict security standards for a wide range of the Government's information classifications representing the majority of day-to-day operational communications.

"BlackBerry continues to lead in the government sector, providing a secure, robust and manageable architecture that is proven and trusted around the world," said Scott Totzke, Director, Government Technology at Research In Motion. "The Australian Government, including its Department of Defence, has now listed BlackBerry as an approved product and DSD has completed its security policy for BlackBerry. We look forward to supporting the Government's various departments and agencies to help ensure maximum advantage and ROI on their wireless deployments."

BlackBerry Wireless Handhelds(TM) continue to meet stringent government security requirements and RIM works closely with regulation committees around the world, such as the Defence Signal Directorate, to continually review and enhance the BlackBerry security architecture.

BlackBerry sets the standard for secure wireless data access with support for Triple DES (Data Encryption Standard), AES (Advanced Encryption Standard) and content protection on the handheld with local data encryption. Additional features include wireless IT policy support, wireless password controls, wireless lock/wipe commands and wireless encryption key regeneration.

The guidance recently issued by the Australian Government confirms that BlackBerry standards conform with security requirements and DSD's security policy which is in line with the use of BlackBerry in government organizations worldwide.

With advanced security capabilities and a comprehensive wireless solution for managing email, phone, text messaging, organizer, Internet and intranet applications, BlackBerry is widely used by government personnel around the world to enhance operations, productivity and responsiveness. Many government organizations also use BlackBerry to support Continuity of Operations Planning (COOP) activities by enabling users to efficiently store emergency preparedness information, standard operating procedures, emergency call lists and other continuity of operations documents on their BlackBerry handhelds.

BlackBerry also supports S/MIME (Secure Multipurpose Internet Mail Extensions) for Java-based BlackBerry wireless devices. S/MIME is an email system independent, Internet standards-based protocol that uses public key cryptography to provide writer-to-reader security features, such as authentication, confidentiality and message integrity.
