【摘要】：作为云环境的重要构成部分,虚拟机的身份管理与认证是云计算安全中的重要问题.由于云计算环境具有大规模、分布式等特点,通常在云内存在多个身份权威.而现有的虚拟机身份证明方案中,身份权威的信息是公开的,因此在应用于云计算环境时,将造成组织结构、虚拟机位置等相关性信息的泄露,与云环境的结构透明、位置无关等特性相违背.提出的虚拟机身份证明,在保障原有认证性和信任关系的情况下,实现了身份证明过程中对身份权威信息的隐藏,避免了上述组织结构、位置等信息的暴露,可支持云环境结构透明、位置无关的特点.此外,该方案实现了对平台属性的安全证明,且证明过程无需身份权威的参与,避免了校验者和身份权威的合谋攻击,进一步提高了方案的安全性和实用性.
[Abstract]:As an important component of cloud environment, virtual machine identity management and authentication is an important issue in cloud computing security. Because cloud computing environment has the characteristics of large scale and distributed, there are usually many identity authorities in the cloud. However, in the existing virtual machine identity proof scheme, the identity authority information is open, so when applied to cloud computing environment, it will cause the leakage of relevant information, such as organizational structure, virtual machine location and so on, and be transparent to the structure of cloud environment. Position independence and other characteristics are contrary to each other. The proposed virtual machine identity certificate can hide the identity authority information in the process of identity proof, and avoid the exposure of the above information, such as organization structure, location and so on, under the condition of guaranteeing the original authentication and trust relationship. Can support the cloud environment structure transparent, the location independent characteristic. In addition, the scheme realizes the security proof of the platform attribute, and the authentication process does not require the participation of the identity authority, avoids the collusion attack between the verifier and the identity authority, and further improves the security and practicability of the scheme.
