45526 另外，一些满足保实性的加密方法，则存在密钥相对单一、敏感性不足等问题。 Moreover, some encryption methods that meet the requirements of reality-preserving have problems of relatively single keys, lacking of sensitivity and so on.
45527 基于此，提出一种基于多阶分数离散切比雪夫变换和产生序列的图像加密方法， An image encryption method was proposed based on multiple-order fractional discreet Tchebichef transform and generating sequence.
45528 该方法使用随机生成的行、列分数阶向量以及通过混沌序列生成的产生序列作为密钥对图像进行加密，在满足实值传输的同时大大扩展了密钥空间。 The proposed method used randomly generated row and column vectors and generating sequence generated by Chaotic sequences as keys to encrypt images, which not only satisfied property of reality-preserving transmission but also greatly expanded the key space.
45529 实验结果进一步表明，该加密方法可以抵抗多种攻击，解密后的图像几乎无失真，具有很好的加密效果以及足够的安全性和顽健性。 The experimental results further demonstrate that the proposed encryption method can resist a variety of attacks, and decrypted images are almost non-distored, which indicate excellent encryption effect, sufficient security and robustness of the method.
45530 针对 FANET 中的实时路由、速率分配和功率控制问题，提出异步的分布式跨层优化（ADCO）方法。 An asynchronous distributed cross-layer optimization (ADCO) method was proposed to solve the problem of jointly considering real-time routing, rate allocation and power control in FANET (flying ad hoc network).
45531 为了解决所提问题，首先设计时延约束的跨层优化框架， And a delay-constrained cross-layer optimization framework was designed to formally represent proposed problem.
45532 然后利用拉格朗日松弛和对偶分解方法把联合优化问题分解为几个复杂度较低的子问题。 Then Lagrangian relaxation and dual decomposition methods was used to divide joint optimization problem into several sub-problems.
45533 ADCO 允许每一个中继节点仅通过局部信息来完成对不同子问题的优化，同时，中继节点利用异步更新机制实现对偶变量的更新。 ADCO allowed each relay node to perform the optimization operation for different sub-problems with lo-cal information, and the relay nodes could update the dual variables based on asynchronous update mechanism.
45534 仿真结果表明，所提方法有效地增加了吞吐量，减少了数据分组的超时率和功率消耗。 The simulation results show that the proposed algorithm can improve the network performance effectively in terms of energy efficiency, packet timeout ratio and network throughput.
45535 社交网络数据是稀疏和嘈杂的，并伴有大量的无意义话题。 The data is noisy and diverse, with a large number of meaningless topics in social network.
