Mobicast-based optimal QoS secure authentication algorithm

为保证无线传感器追踪网络(WSTNs)移动组播服务质量(QoS)和安全性,在Mobicast协议基础上提出一种最优QoS安全认证算法,将被监测实体运动速度与组播应用服务需求相关参数向量化,并在其基础上得出满足最优QoS的多级μTESLA认证协议级数M的函数表达式.分析和仿真结果表明,该算法能够对达到特定QoS需求所需的相应安全认证密钥级数进行有效分析和预测,且对于网络能耗和通信实时性的影响是可以接受的.

To ensure the quality of service（QoS） and security of mobile multicast in the wireless sensor tracking networks（WSTNs）,an optimal QoS secure anthentication algorithm is presented,which makes the speed of the monitoring entity and relevant parameters of multicast applications to vectorization.Furthermore,the level number M of the authentication protocol and the multi-level μTESLA meeting with the optimal QoS are derived.The analysis and simulation results show that this algorithm can analyze and predict effectively the corresponding key level of authentication under the certain QoS requirements,and the impact on network energy consumption and real-time communication is acceptable.
