Design And Implementation Of FPGA-based One-way GAP-specific Control System

Gap technology is an emerging safe network technology, which can be as powerful curtain between confidence network and non-confidence network,in recent years. The technology adopted include categories of data fragment reassembly, protocol conversion, cryptography, intrusion detection, virus, and keyword filtering, authentication and audit and so on. In the confidentiality requires of secret information, it require high security classification data not to low security classification network, but the low security classification data can be to high security classification network; If we retained only the one-way data flow it could implement the require of data confidentiality, in such circumstances to bring about the demand for one-way gateway. Because fiber media converter is unidirectional, using fiber as the media of GAP could guarantee unidirectional transport. The thesis propound more detailed design about how to control one-way GAP to send and receive data, as well as reliable protection of data transmission, the control system of one-way GAP. This design is realization of the main data processing and control on FPGA. As a result, this thesis main discuss the implementation of control system on FPGA.
