21955 已有的基于格的密文策略属性基(CP-ABE)方案只能通过矩阵运算方法进行加解密，加解密效率不高，而效率较高的基于理想格的密钥策略属性基(KP-ABE)方案又存在对各类实际应用场景适应性较差的问题。 The existing Ciphertext-Policy Attribute-Based Encryption (CP-ABE) schemes from lattices are inefficient while they are performed in matrix operation, and these Key-Policy Attribute-Based Encryption (KP-ABE) schemes from ideal lattices with higher efficiency are inadaptable to most practical application scenarios.
21956 为解决上述问题，该文利用理想格上的算法生成主密钥和密钥，同时在多项式环上进行运算，极大地提高了加解密效率； To solve these problems, the new scheme generates master keys and secret keys by the algorithms based on ideal lattices and the whole scheme is computed over a polynomial ring, thus its efficiency of encryption and decryption can be greatly improved.
21957 通过在原属性集合中添加虚拟属性，方案成功结合访问结构生成密文，同时授权用户可以构建出满足解密条件的子集，从而实现方案的正确解密； The ciphertexts associated with access structure are successfully generated by adding some virtual attributes to the original attribute set. Meanwhile, the authorized user can build a subset based on these virtual attributes for decrypting the scheme correctly.
21958 还利用单个陷门矩阵生成密钥，有效降低了公共参数和主密钥的数量。 And the secret keys are generated by a single trapdoor matrix, which reduces the number of public parameters and master keys effectively.
21959 最终该文构建了一个基于理想格的支持门限访问结构的高效 CP-ABE 方案，并证明方案在环上容错学习(R-LWE)假设下是选择性安全的。 Finally, an efficient CP-ABE scheme for flexible threshold access structures on ideal lattices is proposed, and its security is reduced to decisional Learning With Errors over Ring (R-LWE) assumption against chosen plaintext attack in the selective security model.
21960 与现有支持门限访问结构的方案的对比分析表明，该文方案公共参数数量更少、效率更高，且对实际应用场景有更好的适应性。 Comparative analysis of similar schemes shows that the new scheme has less public parameters and higher efficiency, and gets better adaptability to the practical application scenarios.

21962 为识别复杂的雷达信号调制模式以及混合体制雷达，该文提出一种基于多站获取脉冲时差参数联合其他脉冲描述字分选的办法，利用多层感知器神经网络得到脉间调制识别结果。 To recognize complex modulation mode of radar signal and hybrid pulse repetition interval radar, this paper proposes a sorting method based on multi-station acquired pulse time-difference parameter combined with other pulse description words, taking advantage of the multi-station TDOA from the same emitter is similar to sort emitter signal pulse, and finally got the recognition result with the Multi-Layer Percetron (MLP) neural network.
21963 该文通过时差参数与其他脉冲描述字去交错解决传统脉冲重复周期估计算法无法对复杂的脉间调制方式进行估计。 Traditional Pulse Repetition Interval (PRI) estimation algorithms estimate complex pulse interval modulation invalidly. In this paper, to solve this problem pulse time-difference parameter and other pulse description words are used.
21964 利用训练好的多层感知器，获取完成去交错后的脉冲序列其特征向量，获得其脉间调制类型识别。 The feature vector of de-interlace pulse sequence is acquired and the result of pulse interval modulation type recognition is obtained with the trained MLP neutral network.
