| 摘 要： | 在天地一体化网络中，为保证节点身份的合法性，需要对节点进行接入认证及切换认证。但是，认证机制的实施将会影响网络性能，因此该文对各种认证组合方案的整体性能进行量化分析。建立天地一体化网络认证与节点通信模型，定义了6种认证协议，给出了4种典型的认证组合方案。定义了平均认证时延与平均认证开销两种性能评价指标。给出了单次认证时延、单次认证开销、认证与切换概率的计算方法。在不同接入持续时间及接入到达率条件下，对各种认证组合方案的性能进行了量化分析。

| Abstract: | In space-ground integrated information network, in order to ensure the node identity, access and handover authentication are required. However, the implementation of the authentication mechanism will affect the network performance, so this article makes a quantitative analysis of the overall performance of various authentication scheme combinations. A network authentication and node communication model are established, six authentication protocols are defined, and four typical authentication combination schemes are given. Two performance evaluation indicators are defined, including average authentication delay and average authentication overhead. The calculation methods of single authentication delay, single authentication overhead, authentication and handover probability are given. The performances of the authentication combination schemes are quantified under different access durations and arrival rate. |
