BlackBerry wants to offer business users on Android and iOS with an even more secure messaging service before the year ends. BlackBerry exec Sunil Lalwani told The Hindustan Times that the company will begin offering BlackBerry Messenger Protected on both platforms for an annual fee of US$30 per device. BBM Protected was initially launched for users with BBOS devices running on BES 5 and BB10 users with gold licenses on BES10 that run on EEM-regulated Work Space mode only.
The messaging service is just like BBM but adds a latter of encryption that is shared exclusively by the sender and the recipient. It has a new random symmetric key for message encryption that means if one of your encryption keys gets compromised it won’t expose all your messages.
