BBM Protected offers an encryption key for each end of the messaging, meaning a hacker has a doubly difficult time breaking into the message. When two users use BBM protected, they have to share a secret passcode to authenticate their identities. That generates an encryption code, securing the conversation.
BlackBerry believes they have created the most secure messaging system available, "BBM Protected is the only secure mobile instant messaging app that uses a FIPS 140-2 validated cryptographic library," they said in a statement. "BBM Protected enables employees to use the same app to securely message colleagues inside the company for work as they do to chat and share with family and friends outside the company."
