摘要:

针对OpenStack 认证机制缺乏细粒度鉴权、数据库利用率和数据安全性不足的问题, 在分析OpenStack 平台架构、虚拟机生成实例流程, 以及安全组件Keystone 与其他服务组件间的交互流程的基础上, 提出一个OpenStack 身份认证改进方案。该方案将LDAP(Lightweight Directory Access Protocol)、RBAC(Role-Based AccessControl)以及SSL/ TLS(Secure Sockets Layer/ Transport Layer Security)安全协议集成到Keystone 安全服务组件中,加强了OpenStack 对于用户和虚拟资源的身份管理的可扩展性和安全性。

关键词: OpenStack 平台, Keystone 服务, 基于角色访问控制, 轻量级目录访问协议, 认证机制

Abstract:

Based on the analysis of the interactive process between the OpenStack’s platform structure, generating process, security mechanism and other service components, an improved ID authentication project is proposed to solve the deficiency of fine-grained authentication, low-usage of database and security flaw of data. This project integrates the LDAP(Lightweight Directory Access Protocol), RBAC(Role-Based Access Control), and SSL/ TLS(Secure Sockets Layer/ Transport Layer Security) into Keystone service, which strengthens the performance of Opentack‘s cloud platform in the aspect of the extension and security of ID management.

Key words: OpenStack, Keystone service, role-based access control(RBAC), lightweight directory access protocol(LDAP), authentication mechanism
