  • Securing out-of-band messages
    Patent number: 8447970
    Abstract: Securing an out-of-band message from a server to a mobile computing device. After requesting a service ticket from a trusted third party (e.g., via a pre-existing ticketing infrastructure), the requested service ticket and a shared secret are obtained from the trusted third party via a first channel. The mobile computing device thereafter sends the service ticket with the shared secret to a server via a second channel. The server encrypts a message (e.g., an SMS message) using the shared secret. The mobile computing device receives the encrypted message from the server via a third channel that is out-of-band relative to the first channel. The encrypted message is decrypted via the shared secret and the decrypted message is provided to a user of the mobile computing device. In some embodiments, the message includes commands for controlling the mobile computing device.
