| 摘 要： | 提出一个分布式的具有多跳认证授权支持的移动Ad Hoc网络方案。该方案利用门限密钥分享技术把认证授权功能完全分散化，每个节点持有一个密钥份额，只有达到门限值规定数量的节点联合起来才能提供认证服务，而认证服务将不仅仅局限于本地节点，多跳范围内的节点也可以参与这项工作。此外，本文还采用多播来取代广播以减少杂项开销。本文解决了多跳认证授权所遇到的技术难题，并通过仿真验证了方案的可行性和有效性。

| Abstract: | This paper proposes a distributed multi-hop certification authority scheme for mobile Ad Hoc networks. In our design, we distribute the certification authority functions through a threshold secret sharing mechanism, in which each node holds a secret share and multiple nodes jointly provide complete services. Certification authority is not limited in a local neighborhood but can be completed within multihop location. In addition, we replace broadcast by multicast to reduce communication overhead. This paper solves some technical problem with multi--hop certification authority. Simulation results confirm the availability and effectiveness of our design. |
