Abstract:
1. A method for secure communication between a first end terminal located in a first secure network and a second end terminal located in a second secure network, said first and second networks being separated by a relatively insecure intermediate network and a relatively secure intermediate network, the method including the steps of: selectively routing, over said relatively insecure intermediate network or said relatively secure intermediate network, a predetermined type of communication identified by a trigger from the first end terminal to the second end terminal over said relatively insecure intermediate network by means of at least one network element triggerable to refer to information held in a storage means to selectively route said communication according to said information held in said storage means; and encrypting said selectively routed communication by means of an encryption engine before it traverses said intermediate network, wherein said at least one network element and said encryption engine are located substantially within said first secure network.
