Abstract

See full text

The invention discloses a method transferring packets between a mobile host device (100) and a source node via a number of independent data networks while maintaining a secure connection. The independent networks may include, for example, the Internet (120), localized Access Zones (110, 140), a Corporate Intranets, a Home Network (130) etc. Problems may occur, for example, when the mobile node is using a co-located care-of address, in which case both IP-in-IP and IPsec tunneling transformations are performed, and the current IPsec and IP-in-IP implementations cannot perform the required tunneling operations on the mobile host. This is because the IP-in-IP and IPsec tunneling when the IP-in-IP tunnel is not the outermost transformation. In an embodiment of the invention, the security policy operated by the mobile host includes a primary security policy and a dynamic secondary security policy that selectively apply specified transformations to certain packets in the data transfer.
