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.
