46406 提出的时变信道模型可用于城市微蜂窝场景时变信道仿真， The proposed model was validated by comparing theroot-mean-square (RMS) of delay spread and angular spread between the simulated and measured results.
46407 也为 5G 动态信道建模的研究提供重要参考。 The channel model proposed can be applied in time-varying channel simulation for urban microcells and it’s also very important to be referred in 5G dynamic channel modeling.
46408 为准确、全面地预测攻击行为并量化攻击威胁，提出一种基于攻击预测的安全态势量化方法。 To predict the attack behaviors accurately and comprehensively as well as to quantify the threat of attack, a quantitative method for network security situation based on attack prediction was proposed.
46409 通过融合攻击方、防御方和网络环境态势要素，依据实时检测的攻击事件评估攻击者能力和漏洞利用率，并计算攻防期望耗时； By fusing the situation factors of attacker, defender and network environment, the capability of attacker and the exploitability rate of vulnerability we reevaluated utilizing the real-time detected attack events, and the expected time-cost for attack-defense were further calculated.
46410 进而设计基于动态贝叶斯攻击图的攻击预测算法，推断后续攻击行为； Then an attack prediction algorithm based on the dynamic Bayesian attack graph was designed to infer the follow-up attack actions.
46411 最后从主机和网络这 2 个层面将攻击威胁量化为安全风险态势。 At last, the attack threat was quantified as the security risk situation from two levels of the hosts and the overall net-work.
46412 实例分析表明，该方法符合实际对抗网络环境，能够准确预测攻击发生时间并合理量化攻击威胁。 Experimental analysis indicates that the proposed method is suitable for the real adversarial network environment, and is able to predict the occurrence time of attack accurately and quantify the attack threat reasonably.
46413 提出一种基于 sketch 数据结构的软件定义测量数据平面硬件模型，并在以现场可编程逻辑门阵列（FPGA）为核心的可编程网络设备 NetMagic 上进行了实现。 A sketch-based data plane hardware model for software-defined measurement was introduced, and it was implemented in the programmable network device NetMagic.
46414 利用部署在硬件 FPGA 高速 SRAM 中的通用 sketch 数据结构高效地采集数据平面流量数据，控制平面收集并缓存统计数据，提供给上层的测量应用使用。 A generic sketch model for collecting flow-level data using high-speed memories on the FPGA was proposed, the control plane collected and cached the data for further process.
46415 使用 count-min sketch和 2-universal 散列函数实现了在高速流量下实时的分组处理和流量统计；使用 Bloom filter 在控制平面恢复流量的原始 5 元组信息，解决了 sketch 数据结构的不可逆问题。 Count-min sketch and 2-universal hash functions in the SRAM of FPGA for real-time traffic counting of high-speed traffic were implemented; Bloom filter was used to rebuild the original 5-tuple data which solved the irreversibility of sketch.
