BlackBerry on Thursday said it received approval from the National Security Agency to sell tools for encrypting phone calls and text messages to US federal government agencies.
The NSA's National Information Assurance Partnership (NIAP) reviews consumer products for government use to ensure stringent security standards are met.
Previously, NIAP has given approval to Apple and Samsung mobile security tools.
BlackBerry's government tools, Secusuite, supports encryption on iOS, Android, and BlackBerry 10 smartphones and tablets, along with all carrier networks and calling over Wi-Fi.
BlackBerry hasn't named any potential government agency partners.
"Call tapping is happening at an alarming rate," said Alex Thurber, SVP and GM of Mobility Solutions at BlackBerry. "In today's connected world, restricting agency employees to only exchange classified information from the desk phone is no longer a viable option, but it could be the new reality if governments don't start securing calls and texts from mobile devices."
The Secusmart Security Card is the centerpiece of Secusmart's technology and is a mini-computer integrated into the micro-SD card. It contains the NXP SmartMX P5CT072 crypto-controller with a PKI coprocessor for authentication. An additional high-speed coprocessor encrypts voice and data communication using 128-bit AES. Text messages, emails and voice communications are then secure from prying ears and eyes.
