Method and system for employing a fixed IP address based encryption device in a dynamic IP address based network

摘要

A network operations center (130) provides secure communication between fixed IP address based encryption devices (114,154) in an enclave (110) and on a handheld communication device (150) deployed on a dynamic IP address based wireless carrier network (140). In communication from the enclave (110) to the handheld device (150) a fixed IP address based data packet (310) is obtained from the enclave (110) and encapsulated into a network data packet (320) which is provided over the wireless carrier network (140) to the handheld device (150) for decapsulating the fixed IP address based data packet (410) from the network data packet (320). In communication from the handheld device (150) to the enclave (110) a fixed IP address based data packet (710) is decapsulated from a network data packet (620) into which it has been encapsulated by the handheld device (150) and provided to the enclave (110).
