Abstract From the Canadian patent

An approach is provided for securely communicating in a wireless network. A cryptographic server generates a command to enable a secure mode of operation for a wireless device, wherein the wireless device can operate in a secure mode and an unsecure mode in support of two-way messaging. The cryptographic server sends the command to the wireless device to activate the secure mode of operation. The secure mode of operation provides transmission of an encrypted message by the wireless device over the wireless network.
