47056 简化了传统安全覆盖网服务（SOS, secure overlay services）的角色节点，并采用周期性更新角色节点以及缓存安全访问路径的策略。 It simplified role nodes of traditional secure over-lay services (SOS), and periodically updated role nodes, and cached security access paths.
47057 SAPA更适用于云计算平台防御 DoS 攻击。 Therefore, SAPA was moreappropriate for cloud computing to defend DoS attacks.
47058 基于云计算泛联路由架构，建立 SAPA 的数学模型并对其性能进行理论分析。 Based on the turn routing architecture of cloud computing, themathematical model of SAPA was built and its performance was analyzed in theory.

47060 并将实验场景扩展到 Test-bed 平台来评估 SAPA 对 DoS 攻击的防御效果。 Also, the Test-bed experiments were performed to evaluate the effectiveness ofSAPA for defending DoS attack.
47061 实验结果表明，相较于 SOS 方法，SAPA 能够更有效地降低 DoS 攻击对通信成功率的影响，并保证足够小的访问延时。 Experimental results show that comparing with SOS, SAPA can degrade the impact ofcommunication success rate caused by DoS attack effectively, and guarantees the access delay small enough.

47063 基于 WSN 监测信号普遍具有的稀疏特性，提出了基于双层压缩感知（double process of compressive sensing）的有损无线链路稀疏信号传输架构，探索低质量无线链路下实时、高精度和高能效的稀疏信号传输方法。 Thanks to the inherent sparse property of signals in WSN, the framework of sparse signal transmission based ondouble process of compressive sensing was proposed, providing an insight into a new way of real-time, accurate andenergy-efficient sparse signal transmission.
47064 首先，将稀疏信号传输过程中的随机分组丢失现象建模为压缩感知的线性降维观测过程（被动 CS 过程）。 Firstly, the random packet loss during transmission under lossy wireless linkswas modeled as a linear dimension-reduced measurement process of CS (a passive process of CS).
47065 然后，针对 WSN 为提高传输效率而采用的长数据分组，数据发送前在发送端引入线性随机降维投影——简易的信源编码操作（主动 CS 过程），避免块状数据丢失的发生。 Then, considering thata large packet was often adopted in WSN for higher transmission efficiency, a random linear dimension-reduced projec-tion (a simple source coding operation) was employed at the sender node (an active process of CS) to prevent block dataloss.
