基于移动agent的云计算身份认证机制研究

针对当前云计算的安全需求,提出了一种适用于云计算环境下的身份认证方案。首先设计出适用于云计算身份认证场景的移动agent(mobile agent)结构模型,然后给出了基于mobile agent的云计算安全认证策略。该方案引入了可信第三方机构对认证agent建立定量信任评估,每次进行认证前通过信任度的判断对认证过程进行控制;在认证完成后,又进一步引入了信任反馈评价机制。理论分析和原型系统的实现表明,提出的云计算认证方案具有一定的可行性和可用性。

Research on cloud computing security authentication mechanism based on mobile agent

Aiming at the current cloud computing security requirements, this paper proposed a novel cloud authentication scheme. Firstly, it designed a structural model of mobile agent and the certification process oriented to cloud computing environment. The authentication scheme introduced a trusted third party which was used to computing agent trust degree by trust evaluation mechanism. Trust value would be used to control every user agent for authentication of the certification. The agent who met the appropriate conditions would increase the trust value and the authenticator who had done incorrect or malicious behavior would reduce the trust value of the agent. Certification processor analysis and implemented prototype show that presented schema can increase the security service level of cloud computing.
