22435 该文将最小色散算法应用到 ADS-B 信号压制式干扰抑制的研究中。 Minimum dispersion method is applied to jamming suppression for ADS-B in this paper.
22436 首先，利用 ADS-B 信号的脉冲特性，将以往只考虑二阶统计量的形式扩展，重新建立 p 范数约束优化模型。 Firstly, based on the pulse characteristic of ADS-B, minimum dispersion method is obtained by solving the constrained optimization issue of p-norm, which expands the case that exploits only the second-order statistics of the array output in past.
22437 然后，提取观测信号更低阶统计量中的有用信息，将解算最优加权矢量转化为一个最优化问题。 Then, the useful information in lower order statistics is used to convert the solution of optimal weight vector into an optimization problem.
22438 最后，解算最优权矢量，对观测信号进行空域滤波，完成 ADS-B 的压制式干扰抑制，并对抑制结果进行性能分析。 Finally, jamming is mitigated by spatial filtering and the performance is analyzed.
22439 文中提供的仿真实验结果验证了算法的有效性，该方法不需要知道 ADS-B 信号来向，也无需估计协方差矩阵。 Simulation results demonstrate the effectiveness of the proposed algorithm. The anti-jamming performance of this method is not limited by the prior knowledge of ADS-B direction and the covariance matrix estimation.
22440 该文针对单调访问结构提出了一个解密成本为常数的具有追踪性的密文策略属性加密(CP-ABE)方案，该方案基于合数阶双线性群实现了标准模型下的适应安全性。 This paper puts forward a traceable Ciphertext-Policy Attribute-Based Encryption (CP-ABE) scheme for Monotone Access Structure (MAS), which is proved secure adaptively in the standard model by using composite order bilinear groups.
22441 在所有已知的追踪性 CP-ABE 方案中，都使用线性秘密共享方案(LSSS)来表示单调访问结构，并用 LSSS 矩阵加密明文数据。 To date, for all traceable CP-ABE schemes, the MAS is represented by the Linear Secret Sharing Scheme (LSSS) and then the data are encrypted by using the corresponding LSSS matrix.
22442 因此，其加密成本都随着 LSSS 矩阵的大小成线性增长，同时解密成本则随着满足要求的属性数量成线性增长。 Therefore, their encryption costs are linear with the size of the LSSS matrix, and the decryption costs are linear with the number of qualified rows in the LSSS matrix.
22443 而在该文提出的追踪性 CP-ABE 方案中，使用最小授权子集集合来表示单调访问结构，并用该子集集合加密明文数据。 However, in the proposed traceable CP-ABE scheme, the MAS is represented by the set of minimal authorized set and then the data are encrypted by using the corresponding set.
22444 因此，其加密成本随着最小授权子集的集合大小成线性增长，对于某些单调访问结构，该文方案具有更短的密文长度和更小的加密成本。 Therefore, the encryption costs are polynomial with the number of minimal authorized set, and for some access policies, the proposed scheme may have shorter ciphertext and lower encryption costs.
