一种安全的基于优先级的应用层多播模型

A Secure Priority-Based Application Layer Model

提出了一种使用于大规模应用层多播的模型SPBHM,采用分层和分组的概念,根据节点的性能对区域节点进行优先级划分,从而动态规划多播组的Leader节点,并对模型的安全做出了综合性的阐述,通过TKS模式负责模型的密钥管理分发,仿真结果显示,该模型以较小的控制开销,获得了较高的数据传输效率和安全特性。

This paper presents the analysis, design and performance evaluation of SPBHM,This secure application layer muhicast model takes the concept of hierarchy and priority, dynamically taking the group member with a high performance as the group leader, This paper also makes a comprehensive statement with the secure issues by TKS to be responsible for the key distribution and management. Simulation results reveal that the model acquires a higher data transmission efficiency and security features with a lower penalty of control overhead.
