文中研究基于IBE的移动自组网安全接入机制,解决移动自组网拓扑动态变化、高时效性、快速切换等条件下的高效认证问题。对比分析各种认证机制的优缺点以及适用的环境,针对移动自组网内部的接入认证、动态组网认证、跨域认证,分别设计相关的认证流程及安全接入实现途径,保证骨干网、接入子网互联互通时的安全可控,为建设移动自组网安全防护体系提供理论依据和技术支撑。 This paper studies the secure ad-hoc access mechanism based on IBE to solve the problem of high-efficiency authentication under the conditions of dynamic ad hoc network topological changes, high timeliness and fast handover. Comparing the advantages and disadvantages of various authentication mechanisms and the applicable environment, we design authentication, dynamic authentication and cross-domain authentication for Mobile Ad hoc networks, and design related authentication procedures and security access approaches respectively to ensure that the backbone network , Access subnet interconnection and exchange of safe and controllable, to provide a theoretical foundation and technical support for the construction of mobile Ad Hoc network security protection system.
