Abstract (en)

[origin: WO03061188A1] Method and apparatus for enabling secure connectivity using standards­based Virtual Private Network VPN IPSEC algorithms in a mobile and intermittently connected computing environment enhance the current standards based algorithms by allowing migratory devices to automatically reestablish security sessions as the mobile end system roams across homogeneous or heterogeneous networks while maintaining network application session. The transitions between and among networks occur seamlessly -- shielding networked applications from interruptions in connectivity. The applications and/or users need not be aware of these transitions, although intervention is possible. The method does not require modification to existing network infrastructure and/or modification to networked applications.
