Blackberry Ltd. said more than 10 million people signed up for the BlackBerry Messenger service (BBM) in the first 24 hours after its release on Monday for non-BlackBerry users. The company says it is processing new users at a rate of 500,000 an hour, with millions more queued up.
"We have absolutely incredible demand we're trying to manage," BlackBerry spokesman Jeff Gadway said. "We're off to a really good start."
What makes BBM different from regular SMS? For one, the application encrypts data traffic in transit between the BlackBerry Server and BlackBerry devices automatically. Here is a step-by-step guide through sending and receiving a BBM. Read the full story.
How Blackberry Messenger Works
1. Encryption key is stored in the user's secure mailbox account.
2. Blackberry messages don't have to be short, but short message service text messages (SMS), in the Latin alphabet, max out at 160 characters. For other alphabets, such as Chinese, the maximum SMS length is 70 characters.
3. Data sent to and from the smartphone is encrypted using the private key retrieved from the user's mailbox.
4. Data remains encrypted in transit and is never decrypted outside of the firewall.
5. Instant messages can only be sent to someone if you know his or her PIN code.
6. Encrypted information travels securely to the smartphone where it is decrypted with the key stored there.
