摘　　要：在实际应用中,研究者发现早前研究的SSAMHFDL模型尽管能够较好地实现软件版权保护,但存在LMS和LD单点故障、LA与LMS之间未加密通讯、不支持LA离线提交授权许可、未区分终端BS版本等问题。为解决这些问题,在原模型的基础上,提出了支持分布式高可用的通用软件授权认证模型DHASAMHFDL,将原有的单点实例更新为分布式集群,引入了第三方CA签发安全证书,区分了终端BS版本并允许BS离线提交授权数据。从实际运用效果看,新模型在解决上述问题的基础上,继承了原模型在许可模式上的优点,支持分布式部署和服务器高可用性,进一步提升了授权服务器的稳定性与可访问性,更加符合实际应用需要。In practical applications,the researchers found that although the SSAMHFDL model studied earlier can better implement software copyright protection,there are single points of failure between LMS and LD,unencrypted communication between LA and LMS,no distinction is made between the terminal BS version,and it does not support LA’s offline authorization submissions.To solve these problems,based on the original model,the researchers proposed a new universal software authorization authentication model DHASAMHFDL that supports distributed high availability,updated the original single-point instance to a distributed cluster,using a third-party CA to issue security certificates,distinguishes the terminal BS version,and allows the BS to submit authorization data offline.From the actual application effect,the new model inherits the advantages of the original model in the licensing model based on solving the above problems,supports distributed deployment and server high availability,further improves the stability and accessibility of the authorization server,and more suitable for actual application.
