To ensure the reliability and safety of the water supply, from the viewpoint of overall management, it would be necessary to establish a system of information management for the pipeline. The monitoring, calculating and analyzing functions of the system serve to give controlling instructions and safe operating rules to the automatic equipment and technician, making sure the resistance coefficient distribution along the pipeline is reasonable; the hydraulic state transition is smooth when operating conditions change or water supply accidents occur, avoiding the damage of water hammer. This paper covered the composition structures of the information management system of long-distance water transmission pipelines and the functions of the subsystems, and finally elaborated on the approaches and steps of building a mathematics model for the analysis of dynamic hydraulic status.展开更多
随着云计算的快速发展及其普及,企业的传统数据安全边界被打破,出现云资产管理混乱、越权、误操作等现象,对用户的信息安全产生巨大威胁。基于此,对目前云计算环境下身份认证和访问管理(identity and access management,IAM)的安全问题...随着云计算的快速发展及其普及,企业的传统数据安全边界被打破,出现云资产管理混乱、越权、误操作等现象,对用户的信息安全产生巨大威胁。基于此,对目前云计算环境下身份认证和访问管理(identity and access management,IAM)的安全问题进行研究,提出结合内生安全思想,采取拟态防御手段构建出一种具有内生安全效应的拟态身份认证和访问管理(mimicry identity and access management,MIAM)体系架构方案,并对其进行详细描述。将该方案分别进行稳定性测试、系统性能测试以及系统安全性评估,实验数据表明,该方案具有可行性和安全性。展开更多
