19416 侧信道攻击是当前云计算环境下多租户间信息泄露的主要途径，针对现有服务功能链(SFC)部署方法未充分考虑多租户环境下虚拟网络功能(VNF)面临的侧信道攻击问题，该文提出一种抗侧信道攻击的服务功能链部署方法。 Side channel attack is the primary way to leak information between tenants in current cloudcomputing environment. However, existing Service Function Chain (SFC) deployment methods do not fullyconsider the side channel attack problem faced by the Virtual Network Function (VNF) in the multi-tenantenvironment. A SFC deployment method is proposed against side channel attack.

19419 基于多视点视频序列视点内、视点间存在的相关性，并结合视点间运动矢量共享技术，该文提出一种面向3维高效视频编码中深度序列传输丢包的错误隐藏算法。 By using the intra-view and inter-view correlations and the motion vector-sharing, a depth map errorconcealment approach is proposed for 3D video coding based on the High Efficiency Video Coding (3D-HEVC)to combat the packet loss of the depth video transmission.
19420 首先，根据3D高效视频编码(3D-HEVC)的分层B帧预测(HBP)结构和深度图纹理特征，将深度图丢失块分成运动块和静止块； Based on the Hierarchical B-frame Prediction (HBP)structure in 3D-HEVC and textured features of the depth map, all the lost coding units are firstly categorized into two classes, i.e., motion blocks and static blocks.
19421 然后，对于受损运动块，使用结合纹理结构的外边界匹配准则来选择相对最优的运动/视差矢量进行基于位移矢量补偿的错误掩盖，而对受损静止块采用参考帧直接拷贝进行快速错误隐藏； Then, according to the outer boundary matching criterioncombining the texture structure, the optimal motion/disparity vector is chosen for the damaged motion blocksto conduct the motion/disparity compensation based error concealment. Whereas, the direct copy is applied toconcealling the damaged static blocks quickly.
19422 最后，使用参考帧拆分重组来获取新的运动/视差补偿块对修复质量较差的重建块进行质量提升。 Finally, for the concealed blocks whose qualities are not ideal, the new motion/disparity compensation blocks reconstructed by the reference frames recombination are applied to improning the qualities of those blocks.

Moreover, the subjectivevisual quality of the repaired area is better in lines with the original depth maps.
