46416 使用 CERNET 骨干网流量数据对原型系统进行的评估结果表明，该原型系统使用极其有限的硬件资源实现了对较大规模网络流量的实时测量，同时具备较好的测量精度。 The CERNET backbone trace to evaluate the prototype system was used, the result shows that it has the ability to use thelimited hardw.
46417 为在网络攻防博弈中占据主动地位，利用 OpenFlow 网络结构提供的网络灵活性，提出一个基于 OpenFlow的网络层移动目标防御方案。 In order to take an active part in network attack and defense, a moving target defense solution on network layerbased on OpenFlow was proposed, using the flexibility of network brought by OpenFlow network architecture.
46418 在网络层，通过对防护区域内通信中的每一跳网络地址进行伪随机变换，对跨区域网络通信的出口端口进行伪随机映射，从而实现通信节点的隐藏以及网络结构的保护。 On the network layer, through mapping the correspondent nodes’ addresses to pseudo-random virtual addresses in the LAN and mapping correspondent nodes’ ports to virtual ports, achieving the hiding of correspond nodes in the whole network and the information of network architecture.
46419 实验表明，该方案有效可行。 Researches verify the system’s effectiveness.
46420 相比于现有移动目标防御方案，该方案易部署、兼容性好，并实现了节点全网的通信保护。 Comparing with existing moving target defense solutions, the proposed algorithm can be deployed easily in the traditional network, and realize comprehensive protection of the corresponding in the whole network.
46421 属性基加密方案被认为是云存储环境下数据资源访问控制的最佳选择， Attribute-based encryption (ABE) is a new cryptographic technique which guarantees fine-grained access control of outsourced encrypted data in the cloud environment.
46422 但是策略更新很大程度上限制了其在实际中的应用。 However, a key limitation remains, namely policy updating.
46423 针对此问题，提出一种支持策略动态更新的多机构属性基加密方案。 Thus, a multi-authority attribute-based encryption scheme with policy dynamic updating was proposed.
46424 该方案引入匿名密钥分发协议为用户生成私钥，有效地保护用户的隐私，并抵抗属性机构的共谋攻击。 In the scheme, an anonymous key issuing protocol was introduced to protect users’ privacy and resist collusion attack of attribute authority.
46425 另外，方案采用动态策略更新算法，支持任何类型的策略更新， The scheme with dynamic policy updating technique was secure against chosen plaintext attack under the standard mod eland can support any types of policy updating.
