Summary: | It cannot satisfy higher levels of security requirements of the space network that just implement protection in only one protocol layer. But, most space mission cannot simultaneously carry on the security in the multiple layers, because of that is easy to have the repetition induction, and introduce shortage of security, and increase development and the operating cost. In this paper, we proposed the layered secure access mechanism at the data link and network layers, expecting that we can establish integration access protection system to prevent intruders from entering the network. When the trust to certain node that has been authenticated changed, the mechanism proposed can automatic reaction and restoration in time. Moreover, it can tolerate the certain intermittent-communication, and avoid increasing development and operating cost because of the multiple layered encryptions, and enhance the security, the compatibility and performance of secure access. |
