随着云计算的不断发展, 越来越多的云服务商利用云平台提供服务, 供云用户进行使用. 由于云平台无法得知云服务的配置和实现, 所以会产生信任缺失问题. 针对这个问题, 国内外提出了各种方法评估云服务的可信度, 但都较少的考虑了评价的客观性问题. 本文提出环境指标的概念, 使用滑动窗口结合主客观评价的方式对云服务进行可信评估, 并通过实验证明该评估方法提高了云服务可信评估的准确性.
With the continuous development of cloud computing, more and more cloud service providers use cloud platforms to provide services for cloud users. The configuration and implementation of cloud services are not clear to the cloud platform, resulting in a lack of trust. Various methods have been proposed in China and abroad to evaluate the credibility of cloud services in response to this problem. However, the objectivity of evaluation is less considered. This study proposes the environmental indicator, using the sliding window combined with subjective and objective evaluation to conduct credibility evaluation of cloud services. It proves through experiments that this evaluation method improves the accuracy of cloud service credibility evaluation.
