摘    要:针对密码云系统的负载均衡问题,提出了一种基于熵权评价的虚拟密码机调度方法(VSMEWE)。为提高密码服务质量、高效利用密码运算资源,以云密码机的CPU、内存、网络带宽和密码卡吞吐带宽等资源的利用率为主要指标评价云密码机的资源状态,根据云密码机的综合评价值比较结果,得出虚拟密码机的迁移选择方案。实验结果表明,所提算法与Entropy算法和Baseline算法相比,具有全局性和时效性,提高了系统负载均衡效果,执行效率也分别提高了6.8%和22.7%。

关 键 词:虚拟密码机调度  密码云  熵权法  差值法  负载均衡  服务质量

Abstract:To balance load in cryptography cloud systems, a Virtual cipher machine Scheduling Method based on Entropy Weight Evaluation (VSMEWE) was proposed. In order to improve the quality of cryptography service and economize resources of cryptography cloud effectively, a virtual cipher machine migration selection solution was presented, according to the comparison results of comprehensive evaluation values of cloud cipher machine. To achieve the best comprehensive evaluation values, it evaluated the resource states of cloud cipher machine with the main indexes including the utilizations of resources, such as CPU, memory, network bandwidth and throughput bandwidth of cipher card. Finally, a migration selection scheme of virtual cipher machine was decided by the scheduling method. Compared with Entropy algorithm and Baseline algorithm, the experimental results show that the proposed algorithm has characteristics of wholeness and chronergy, the effect of load balancing is improved, and the execution efficiency is increased by 6.8% and 22.7% respectively.
Keywords:virtual cipher machine scheduling  cryptography cloud  entropy weight method  differential method  load balancing  Quality of Service (Qos)
