云计算环境中优化资源分配模式的椭圆曲线加密方法研究

Research on Elliptic Curve Cryptography for Cloud Resource Assignment

调动云当中不同厂商的设备计算资源的方法目前鲜有研究。一方面需要优化已知资源分配并检索是否出现新的资源,另外一方面云计算设备的鉴权也是实现这一目的必须解决的问题。本文重点就云端资源使用的安全性解决方案进行研究,提出一种面向优化资源分配模式的椭圆曲线加密算法。该算法作用于云计算资源鉴权上,为云端应用寻找适合的计算资源匹配服务计算需求且优化计算成本。算法中的每个密匙都必须经过用户和云端设备的双重鉴权。基于仿真实验,本文验证了所提算法在云环境计算资源自动选取及安全性方面的性能改善。

The method used for arrangement of cloud computing resources of different vendors is less researched in the area of cloud computing. On one hand, this method needs to optimize detected resources＇ arrangement and to detect if new computing components are added. On the other hand, the authorization of cloud computing component has to be realized carefully. The security solution for cloud applications are carefully studied, and an Elliptic Curve Cryptography for Cloud Resource Assignment （ECCC） is proposed in this paper. ECCC works on authorization process of cloud computing, to search suitable cloud resources and find corresponding needs and optimized cost. Each and every key in ECCC has to be double authorized by both user and cloud components. According to simulation results, ECCC is proved of its advantage in searching propagate cloud resources and good security performance.
