面向高能物理计算平台的无认证文件共享设计与实现OA

[Objective]To meet the file sharing needs in the computational platform and interactive analy-sis workbench,this paper designs an authentication-free mechanism for instant,secure sharing via public links.[Methods]Leveraging the INK global authentication framework,permission control logic is implemented using the Linux UGO permission model in conjunction with meta-data management.The XRootD framework is employed to abstract underlying differences in heterogeneous distributed storage systems.Multi-dimensional security mechanisms are integrat-ed to safeguard data transmission and access,culminating in a precisely controlled authentica-tion-free file-sharing paradigm.[Results]The mechanism has been successfully deployed on INK workbench,allowing secure,fast public link generation for sharing.XRootD downloads are only 3.2%slower than ordinary downloads from a single-server,with strong performance in distributed storage.[Conclusions]Global authentication,heterogeneous storage adaptation,and fine-grained con-trols deliver a complete,efficient solution for cross-platform distributed file sharing.
