Side-channel attacks represent one of the most powerful category of attacks on cryptographic devices with profiled attacks in a promi- nent place as the most powerful among them. Indeed, for instance,...
助飞反潜鱼雷落点精度的Bayes评估方法
助飞反潜鱼雷 落点精度 Bayes方法 定位误差
2018/1/6
针对助飞反潜鱼雷落点精度指标特点(采用标准方差σ表示）以及评估该指标过程中遇到的本舰定位误差过大的实际问题，提出对该指标采用验前信息的二项分布Bayes假设检验方法进行综合评定；采用数据预处理方法将舰位定位偏差分离。算例表明：该方法能有效利用试验数据，对助飞反潜鱼雷落点精度指标进行科学充分的评定和估算。
调整型Bayes序贯验后加权战术导弹批抽检方法
调整型抽样检验 序贯验后加权检验 战术导弹 连续批
2017/11/8
针对战术导弹批抽检为连续批、批量小的特点，结合Bayes理论，融入调整型检验的思想，提出了一种基于调整型序贯验后加权检验的战术导弹批抽检方法；该方法结合指标的先验信息，依据比例系数调整双方风险，预先设定3种宽严不同的序贯验后加权抽样检验方案，有效利用历史检验批的抽检结果；算例结果证明：该方法能适用于小子样条件下的战术导弹批抽检。
