BBM Protected to come to Android and iOS in the fall, upping the encryption ante3
The first version of BBM Protected will work only on BB 6 devices and Regulated BB10.2+ activations. Regulated+Balance activations are set for a September/October time-frame. It goes without saying that both you and the conversation parties have to be using BBM Protected for the extra protection to kick-in. Unfortunately, it isn't clear whether BBMP will be offered to users free of charge, or on a paid basis. Enterprise users, however, will be charged a monthly subscription.
Some time ago, BlackBerry promised that the service will bring an “unrivaled level of trust in enterprise messaging with end-to-end encryption of messages.” Hopefully, the next level of encryption will deliver according to the company's best traditions in security.
