| Abstract: | According to the space communications’ especial environment such as the exposed channel,the large coverage area and the limited bandwidth resources,this paper analyzes and compares the advantages and disadvantages of two types of conventional data encryption algorithm,symmetric encryption and asymmetric encryption.After mixing the two types of algorithms and making a brief analysis of the feasibility,a data protection strategy is designed to ensure that the space data can be transmitted in security.Theoretical analysis and simulation results show that the proposed strategy is fairly practical. |

| Keywords: | space communication security protocol symmetric encryption asymmetric encryption security transmission data protection |
