BlackBerry has seriously beefed up its already secure BBM chat system. BBM has been known for its end to end encryption, but BlackBerry is taking it to the next level. Although difficult to break BBM's encryption, if it was broken an intruder could see everything you said. BlackBerry will change this by issuing every message its own encryption key in a version called BBM Protected. By having separate keys on a per message basis, BlackBerry will significantly increased the security of BBM.
BBM Protected will only be available for corporate-controlled BlackBerry devices. It will be available with a new enterprise suite launching in June. Personal users as well as Android and iOS users will have to wait to get their hands on the technology. At some point, we will all hopefully have individual encryption keys on a per message basis.
