21675 现有的基于整数的全同态加密方案是针对两个参与者“一方加密，一方解密”(一对一)设计的，计算效率普遍低，明文空间小，不能应用于大数据、云计算等环境。 The existing integer-based homomorphic encryption schemes are designed only for two participants, namely, one party encryption and one party decryption (one-to-one), whose computational efficiency is generally low, plaintext space is small, so it can not be applied to big data, cloud computing and other actual scene.
21676 为此，该文提出一种“多方加密，一方解密”(多对一)的全同态加密方案，该方案在保证安全性的基础上简化密钥生成过程，并在全同态运算过程中给出能够正确解密的加密方个数的具体范围。 Therefore, a full homomorphic encryption scheme with multi-party encryption, one party decryption (multiple to one) is presented. The scheme simplifies the key generation process on the basis of guaranteeing the security, but also gives the range of the number of encrypted parties that can be decrypted accurately in the process of homomorphic operation.
21677 同时，在随机预言机模型下，基于近似最大公因子问题证明了方案的安全性。 Meanwhile, in the random oracle model, the security of the new scheme is proved based on approximate Greatest Common Divisor (GCD) problem.
21678 数值结果表明，该方案与已有方案相比不仅扩展了数据传输量，而且提高了效率。 Numerical analysis demonstrates that the presented scheme can not only extend the data traffic, but also improve the efficiency by comparing with the existing schemes.
21679 模拟实验表明，该方案在整数范围内具有可行性，满足用户对系统响应的需求，最后将明文空间扩展为3 bit，并与1 bit的方案做出了实验上的对比分析。 Simulation results show that proposed scheme is more practical in the range of integer, and meets the requirements of the users to the system response. Finally, the plaintext space is expanded to 3 bit, comparing and analysing the experiment with the scheme of 1 bit.
21680 间歇采样转发干扰是一种先进的密集假目标干扰技术，该技术基于“欠采样”原理对雷达信号进行低速率间歇采样处理，具有干扰快速响应、抗捷变能力强等优点，能够使雷达无法检测真实目标，甚至使信号处理系统过载。 Interrupted Sampling Repeater Jamming (ISRJ) is an advanced intensive false-target jamming with the advantages of fast interference response, anti-agile ability and so on. The radar signal is intermittently sampled with low-rate based on the principle of the under-sampling method, so that the radar can not detect the real targets and the jamming may overload the signal processing system.
21681 该文针对间歇采样转发干扰样式，基于模糊函数理论，首先设计了一种抑制该干扰的特殊雷达工作波形，即“稀疏多普勒敏感波形”，这种波形通过破坏干扰信号多普勒频率上的输出连续性实现对干扰信号的抑制； This article mainly focuses on the Interrupted Sampling Repeater Jamming. A sensitive Doppler sparse waveform is designed based on the ambiguity function theory to suppress the interference, which destroys the continuity of the interference signal output on different Doppler and suppresses the output of the intensive interference.
21682 然后，基于该波形在时域上的等间隔副瓣特性，提出一种时域上的“滑窗抽取检测”方法，在抗干扰的同时实现目标检测； Based on the analysis of the equivalent interval side lobe, a method of sliding window extraction detection is proposed to achieve effective target detection while anti-jamming.
21683 最后，理论分析和仿真实验验证了该设计波形的干扰抑制有效性，以及“滑窗抽取检测”方法在干扰背景下的良好目标检测性能。 Theoretical analysis and simulation experiments demonstrate the effectiveness of the interference suppression and the target detection performance in the interference.
21684 在部署分布式控制平面的软件定义网络中，控制器与交换机的关联仅以数据流请求的数量分布作为控制资源分配的依据。 In Software-Defined Networking (SDN) with distributed control plane, the switches are assigned to controllers using only the quantity distribution of flow requests as the basis of resource allocation.
