5174 将多数加解密工作外包给云服务器，减轻了用户客户端的计算负担。 Most of encryption and decryption were out-sourced to cloud servers so that it reduced the computing burden on the user's client.
5175 安全分析表明，所提方案能抵御针对性选择明文攻击。 The security analysis show that the proposed scheme resists the selective chosen plaintext attack (SCPA).
5176 交换交叉立方网络是新型互连网络拓扑结构研究的最新成果之一，它同时继承了交换超立方网络和交叉立方网络在网络直径、连接边、成本等方面优点，表现出更高的性价比，有望成为多处理器并行计算机的一种更加优化的组织形式。 Exchanged crossed cube(ECQ) is one of the latest achievements in the research of topology of novel intercon-nection networks. ECQ is a more optimized form of organization for multi-processor parallel computers, which retains the advantages of exchanged hypercube and crossed cube in terms of the smaller diameter, fewer links, and lower costfactor, and which indicates more balanced consideration.
5177 然而，目前，交换交叉立方网络尚未正式引入多处理器并行计算机。 However, so far, ECQ hadn't been formally introduced intomulti-processor parallel computers.
5178 影响交换交叉立方网络应用和推广的主要原因之一是其可靠性研究尚不系统，其中以诊断度为代表的运行可靠性的研究最为迫切。 One of the main reasons was that its reliability research wasn't yet systematic. Among them, the operational reliability represented by diagnosability was the most urgent.
5179 基于此，以交换交叉立方网络为研究对象，在得到交换交叉立方网络相关拓扑性质的基础上，通过理论推导和仿真实验证明的方式， ECQ was taken as studyingobject, after topological analyzing, some important topological properties of ECQ were introduced, which determines the(t,k)-diagnosability of ECQ(s,t) under the PMC model by theoretical deduction and simulation experiments.
5180 首次得出了交换交叉立方网络 ECQ(s,t)在 PMC 模型下的(t,k)-诊断度，进一步补充完善了交换交叉立方网络的可靠性指标，为后续的应用和推广提供了有力的技术支撑。 Simulation results show that ECQ reliability complement and improvement, which provides strong technical support for subsequentapplication and popularization.
5181 信道编码方案中的极化码是 5G 通信领域中的研究热点。 Polar code in channel coding schemes is a research hotspot in 5G communication field.
5182 极化码在串行抵消译码下容易受到差错传播的影响，在中短码长上的性能并不理想。 Polar code is suscepti-ble to error propagation under successive cancellation decoding, and the performance of the code at short and mediumblock lengths is not ideal.
5183 针对这些问题，在不同仿真情况下对系统极化码和非系统极化码的性能差异性进行了研究。 For the problems, the performance difference between systematic polar code andnon-systematic polar code was studied under various simulation conditions.
