Abstract:
A mechanism for generating an address of a cyphertext component of a VPN router in a nested VPN system using an address of a plaintext domain so that a PTX domain has no knowledge about IP addressing in a CTX domain and vice versa. The mechanism advantageously avoids storing correlation between CTX addresses and PTX addresses, thereby maintaining a zero information requirement in a nested VPN routing.
