| 摘 要： | 首次提出了一种安全高效的触发式多播源认证协议,解决了TESLA协议中存在的密钥使用率低和通信量高的问题。结合随机概率转发机制,降低因网络丢包导致的认证时延增大问题并提高报文交付率。性能分析和仿真结果显示在连续密集的广播报文流条件下,协议具备了TESLA协议相同的性能。在稀疏或随机的广播报文流条件下,能将密钥使用率提高约36倍,并减少通信量约5.1倍,显著优于TESLA协议,该性能会随着广播报文速率的降低进一步的提高。

| Abstract: | An efficient triggered multicast source authentication protocol was put forward. This protocol can offer higher utilization ratio of key and lower communication overload, which remain problems in TESLA. The probabilistic resilient multicast scheme was combined to reduce the authentication delay and packet loss in network. Simulation results show that this protocol possesses the same performances with TESLA under the condition of intensive broadcast rates. However, under the condition of sparse or random broadcast rates, it can improve utilization ratio of key by about 36 times and reduce the communication overloads by about 5.1 times than TESLA, and this performance will be further increased with lower of broadcast rates. |
