24285 在可搜索加密的云服务中，数据拥有者往往更希望将数据文件以密文的形式分别存储到多个云服务器，从而提高授权用户对云端数据的检索效率以及对大型数据的处理能力。 In the searchable encryption services provided by cloud severs, data owners expect that their data files can be partitioned and stored to multiple cloud severs with the form of ciphertext, so as to improve the searching efficiency of authorized users and the processing ability of big data.
24286 基于此，该文提出一种基于云存储的多服务器多关键词多用户可搜索加密方案，该方案被证明是 IND-CKA(adaptive Chosen Keyword Attack)安全的，且同时具备关键词陷门的安全性。 For this issue, a multi-sever multi-keyword searchable encryption scheme is proposed based on cloud storage, and the proposed scheme is proved to be IND-CKA (adaptive Chosen Keyword Attack) secure coexisting with the secure trapdoor.
24287 相对于单服务器可搜索加密，该方案在保证数据机密性的前提下能够对其进行高效检索，并能够在关键字索引中不完全包含所检索的多个关键词或者不存在某个文件包含所有被检索的多个关键词的情况下，更精确地进行检索。 Compared with the single sever searchable encryption, the proposed scheme can not only guarantee the data security, but also provide more accurate retrieval service when the keyword index or any one file does not contain all of the searching keywords.
24288 传统无损压缩算法对屏幕图像的压缩效果不佳。 Traditional lossless compression algorithms are not efficient for screen content coding.
24289 该文根据典型屏幕图像的特性，以 LZ4HC(LZ4 High Compression)算法为具体实现基础，提出一种基于串匹配的高性能低复杂度(String Matching with High Performance and Low Complexity, SMHPLC) 的屏幕图像无损压缩算法。 To take the full advantage of special characteristics of screen content, a lossless compression algorithm based on String Matching with High Performance and Low Complexity (SMHPLC) is proposed.

24290 相对于传统字典编码无损压缩算法，新算法提出了以像素为搜索和匹配单位，对未匹配串长度、匹配串长度以及匹配偏移量这 3 个编码参数进行联合优化编码，并对参数进行映射编码。 The main new ideas are using pixel instead of byte as the basic unit for string searching and matching, adopting joint optimal coding of three parameters of literal length, match length and offset and mapping for three parameters.
24291 实验结果表明，SMHPLC 具有高性能和低复杂度的综合优势，大幅降低编码复杂度，提高了编码效率。 Experiment results show that SMHPLC has both high coding efficiency and low complexity.
24292 使用移动的文字和图形类的 AVS2 通用测试序列作为测试对象，对于 YUV 和 RGB 两种格式，SMHPLC 算法比 LZ4HC 总体节省码率分别为 22.4%，21.2%，同时编码复杂度降低分别为 35.5%，46.8%。 Compared to LZ4HC, SMHPLC not only has a coding complexity reduction of 34.6%, 46.8%, but also achieve overall bit-rate saving of 22.4%, 21.2% in YUV, RGB color formats respectively for AVS2 common test sequences in moving text and graphics category.
