在 ROPP-BR 策略中,该文综合考虑频谱资源消耗和链路故障概率,分别设计了工作与保护路径的链路代价函数,以较小代价分别选择业务可靠性高且频谱资源消耗少的备选工作与保护光路。 |
In the ROPP-BR, an adaptive adjustment working and protection link cost functions are devised to effectively select the alternative working and protection light-paths respectively which have high reliability and consume a small amount of spectrum resources in the multi-link failure. The cost function sufficiently considers the spectrum resources consumption and the link failure probability for both working and protection paths. |

为满足业务差异化的可靠性需求,ROPP-BR 策略设计了一种面向可靠性的概率保护机制,建立了业务可靠性评估模型,在满足业务的可靠性需求的限制下灵活地配置概率保护路径。 |
Meanwhile, in order to satisfy the differentiated reliability requirements, a reliability oriented probability protection mechanism is introduced. And a theoretical analysis model is established to estimate the service reliability for light- paths in optical networks with probability protection, so the probability protection path can be flexibly configured under the restriction of the reliability requirements of the request. |

当业务将要被阻塞时,该文提出一种基于极大团的保护光路重配置方法,对网络中的业务保护资源进行重配置,提高保护频隙的共享度。 |
Moreover, for further improving protection sharing efficiency, when the request will be blocked for shortage of idle spectrum resource, a backup reprovisioning method based on maximum clique, is put forward to reconfigure the protection paths and spectrum resources. |

仿真表明,所提策略兼顾了带宽阻塞率与可靠性性能,有效地降低了保护资源冗余度。 |
The simulation results indicate that the proposed ROPP-BR strategy can synthetically consider the performance of bandwidth blocking probability and service reliability, and effectively reduce the redundancy of protection resources. |

属性基加密因其细粒度访问控制在云存储中得到广泛应用。 |
Attribute-Based Encryption (ABE) scheme is widely used in the cloud storage due to its fine-grained access control. |

但原始属性基加密方案中单授权机构带来了分发私钥的计算瓶颈与信任问题。 |
However, the single authority can lead to the trust issue and the computation bottleneck of distributing private keys in the original ABE schemes. |

为解决上述问题,该文基于素数阶双线性群构造了一种分布式属性基加密方案,方案中授权机构由多个权威中心和多个属性中心组成。 |
To solve these problems, a distributed ABE scheme that consists of a number of central authorities and multiple attribute authorities, is constructed based on the prime-order bilinear group in this paper. |

权威中心负责系统建立及用户身份相关密钥生成,且每次用户私钥申请过程中只需一个权威中心参与工作,采用多权威中心的目的是提高系统的稳定性和降低权威中心的计算量; |
Here, the central authority is responsible for establishing the system and generating the private key for the user, and a single private key is generated by only one central authority. In order to improve the stability of the system and reduce the calculation of the center authority, a plenty of central authorities are adopted. |

属性中心负责不同的属性域,相互独立甚至不需要知道其它属性中心的存在。 |
The attribute authority, which is independent of each other, is responsible for managing different attribute domains. |

同时,该方案的密文长度与属性数量无关,为一个常值; |
At the same time, the ciphertext length of the proposed scheme has nothing to do with the number of attributes, therefore, it is a constant. |
