The Chalk™ Pushcast™ Software provides security features that protect content that authors send to the Chalk Pushcast Player. The Chalk Pushcast Software encrypts all user names and passwords, email addresses, and BlackBerry® device PINs that authors sends to the Chalk Pushcast Player.

The Chalk Pushcast Software security framework builds upon the security infrastructure of the devices. The Chalk Pushcast Software and security infrastructure for devices are designed to make sure that data is only available to Chalk Pushcast Player users that the Chalk Pushcast Software authenticates.

The Chalk Pushcast Software uses SSL to protect content that authors send to the Chalk Pushcast Player. The Chalk Pushcast Software uses the Triple DES encryption algorithm to encrypt personal data. Triple DES encryption protects the data that authors send to the Chalk Pushcast Player using a private key that only the Chalk Pushcast Software and Chalk Pushcast Player know.
