47556 从而实现了对 SM4 的故障注入攻击。 The proposed attack is made to an unprotected SM4 smart card.
47557 利用该方法对无防护 SM4 算法的能量曲线进行了实际故障注入攻击的实验表明，该攻击方法行之有效，并简化了现有针对 SM4 的差分故障攻击方法，提高了攻击效率。 Experiment shows that this attack method isefficient, and which not only simplifies the existing differential fault attack ,but also improves the feasibility of the attack.
47558 在日趋紧张的频谱资源环境中，不依赖固定基础设施和固定频谱分配策略的认知 ad hoc 网络相关技术已经获得了十分迅速的发展。 In the environment of scarce spectrum resources, cognitive ad hoc network which is independent with infrastruc-ture and fixed spectrum allocation policy，has been also developed quickly.
47559 但是，认知 ad hoc 网络的多信道路由特点使其收益与风险并存，面临着严重的安全威胁困扰。 Due to the characteristic of multi-channel routing,cognitive ad hoc network is commonly perceived as an environment offering both opportunities and threats.
47560 为深入理解多信道路由安全威胁，掌握其防御对策的研究现状及发展趋势，从节点路由和多信道选择这2 个层面细化出具体的威胁类型，归纳目前的典型防御对策， To further un-derstand the multi-channel routing threats, the current research situation and development trend, the types of threats wereanalyzed in terms of the node routing and the multi-channel selection, and several typical security methods were concluded.
47561 总结出保障认知 ad hoc 网络安全的首要前提是在认知节点之间建立信任关系， Meanwhile, the most important solution to keep the security of cognitive radio network was found to build trust relationshipamong cognitive users.
47562 而信任管理正是解决多信道路由安全威胁的基础。 Trust management was just the basic technology to solve the security problems of multi-channelrouting.
47563 最后，针对目前多信道路由及其防御对策研究中存在的亟待解决问题，明确了一些有待继续研究的方向。 Finally, the current problems of related works and research trends in this area were discussed.
47564 为了克服有限精度效应对混沌系统的退化影响，改善所生成随机序列的统计性能，设计了一种新的基于六维 CNN（细胞神经网络）的 64 bit 伪随机数生成方法。 To overcome the degradation characteristics of chaos system due to finite precision effect and improve the sta-tistical performance of the random number, a new method based on 6th-order cellular neural network (CNN) was given toconstruct a 64-bit pseudo random number generation (PRNG).
47565 在该方法中，通过控制六维 CNN 在每次迭代过程中的输入输出，改善了混沌退化对随机数的性能影响， In the method, the input and output data in every iterationof 6th-order CNN were controlled to improved the performance of the random number affected by chaos degradation.
