Abstract
The present disclosure describes a method for protecting real-time data exchanged between a mobile electronic device and a VPN gateway over a communications link. The method comprises: establishing a first VPN connection between the mobile electronic device and the VPN gateway through the communications link; 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; providing key information to at least one of the mobile electronic device or VPN gateway through the first VPN connection; and exchanging real-time data packets between the mobile electronic device and the VPN gateway through the second VPN connection, wherein the key information is for encrypting and decrypting the real-time data packets exchanged through the second VPN connection.
