Satellite signal is excellent broadband, can provide the same information in a wide range, but there is a disadvantage that much less of the security level of the data. Therefore, supplementation of safety is a serious problem than anything in the satellite communication. In this paper, it was simulated by applying ARIA in encryption technique and by applying transport mode, tunnel mode in security header AH and ESP in order to examine the effect of IPsec VPN. In addition, we had compare with general services that do not apply encryption in order to analyze the impact of the encryption algorithm. Channel, by applying the Markov channel and adding AWGN, is constituted a satellite communication environment. In case of retransmission based error control scheme, we applied Type-? HARQ scheme and Type-? HARQ scheme which are performance is a good way in recently, and it is constituted by a turbo code and BPSK modulation scheme. we were analyzed performance in BER and Throughput in order to compare the simulation more effectively.
