  • Method and apparatus for anonymous IP datagram exchange using dynamic network address translation
    Patent number: 8549285
    Abstract: Methods, apparatus, system and computer program are provided for concealing the identity of a network device transmitting a datagram having a network layer header. A unique local identifier and broadcast address are determined in accordance with a next-hop address. A partially encrypted network layer header is determined by encrypting a plurality of identifying portions of the network layer header, where one portion of the network layer header is the unique local identifier. The datagram is encapsulated with another network layer header whose address is set to the broadcast address. The encapsulated datagram can be received and detunneled, and an address of a recipient can be extracted from the network layer header. The datagram is then admitted into a network domain.
