46296 通过可信中心与车辆协同生成公私钥对和假名，摆脱了系统安全对防篡改装置的依赖。 The public and private keys and pseu-donyms were jointly generated by the trusted third party and vehicle, so the system security didn't depend on the tamper device.
46297 分析表明，该方案能够实现可认证性、匿名性、可追踪性、不可链接性、前向与后向安全性等多种安全性能， The scheme can realize authentication, anonymity, traceability, unforgeability, forward or backward security, and so on.
46298 并在随机预言模型下证实了该方案能够抵抗 Type I 与 Type II 攻击； Furthermore, under the random oracle model, the scheme can resist Type I and Type II attacks.
46299 该方案采用无证书的认证方式，有效减轻了系统存储负载， Because there is no need to use certificates during authentication, the system storage load is effectively reduced.
46300 同时方案在非线性对运算基础上，实现消息的批量认证，有效提高了认证效率。 At the same time, the scheme realizes the batch message authentication on the basis of pairing-free operation, so the authentication efficiency is improved.
46301 因此，该方案在资源受限的物联网或嵌入式环境中，有着重要的理论意义与应用价值。 Therefore, the scheme has important theoretical significance and application value in the resource-limited internet of things or embedded environment.
46302 针对分布式软件定义网络中控制平面可靠性差和控制器负载不均衡问题，提出一种基于可靠性评估的多控制器均衡部署策略。 The control plane has low reliability and controller loads were unbalanced in distributed software defined net-works, and a multi-controller balancing deployment strategy based on reliability evaluation was proposed.
46303 首先，通过综合权衡节点效能和路径质量评估节点可靠性，并在网络中设定均衡因子，优化控制器部署位置； Firstly, node reliability was evaluated by weighting node efficiency and path quality, optimizing the controller location with balancing factor.
46304 然后，改进 k-center 聚类方法，引入冗余函数，根据节点吸引度和控制器负载均衡率完成交换机分配，实现合理的 SDN 子域规划。 Then based on improved k-center clustering, the redundant functions was introduced and the switch allocation was completed according to node attractiveness degree and controller load balancing rate, achieving a reasonable SDNsub-domain planning.
46305 仿真结果表明，与现有策略相比，所需控制器数量平均减少 22.1%， The simulations show that compared with the existing strategy the number of required controllers is reduced by an average of 22.01.
