Patent ID: 8239934

Claim:
A method for protecting real-time data exchanged as packets between a mobile electronic device and a VPN gateway during a media session over a communications link that includes a wireless network, the method comprising: establishing a first VPN connection between the mobile electronic device and the VPN gateway through the communications link, the first VPN connection using a first key-based encryption algorithm to protect data exchanged therethrough; establishing, while the first VPN connection is established, a second VPN connection between the mobile electronic device and the VPN gateway through the communications link, the second VPN connection using a second key-based encryption algorithm to protect data exchanged therethrough, wherein the second algorithm comprises a lower-bit encryption algorithm than the first algorithm; providing key information for the second VPN connection to at least one of the mobile electronic device or VPN gateway through the first VPN connection, wherein the key information is for encrypting and decrypting the real-time data exchanged through the second VPN connection; and exchanging real-time data packets between the mobile electronic device and the VPN gateway through the second VPN connection.
