A novel practical approach for establishing security in the communication satellites

This paper describes a new approach for establishing security in communication satellites for prevention of hackers transpire. Nowadays, by increasing of the needs for world mobile communications, using of the satellites is necessary. Therefore security for transmitted information between the satellites and ground stations is really important. This paper presents a hardware firewall and it´s implementation with VHDL language on FPGA. We will show that the designed system in this paper moreover has high speed and performance, also has both low power consumption and low utilized space. To increase the processing speed and reduce the signalling volume related to external memories, which are linked to FPGA are many times slower than the processing speed of FPGA, we have used and applied embedded memories of FPGA in this design, we have Mixed it with pipeline technique, so a high performance with low power consumption has been achieved. The advantages of this proposed architecture, have solved the processing bottlenecks and have made it plausible to be used in the space environment in the communication satellites.
