密码服务器运算资源可扩展管理研究

Research on Extensible Resource Management of Crypto Server

资源的可扩展管理是集群式密码服务器设计中的关键问题。本文通过分析密码运算的特点,设置算法线程代理密码芯片的运算资源,并在系统管理层建立资源信息表、注册算法线程与管理层的通信句柄及对应算法资源的属性,使系统管理机可以通过资源信息表监控、调度、增/删底层运算资源。该方法实现了系统资源的可扩展管理,并支持集群系统内多密码芯片并行运算资源的调度管理。

Extensible resource management is one of the key issues in the design of crypto cluster server.Based on the analysis to features of crypto processing, this paper presents a method to use crypto algorithm threads delegate the processing resource of crypto chips.An algorithm resource table is also designed in the manager server which used to register the connection handles and the corresponding algorithm attributes.By registering the attributes with the connection handle, the manager can monitor, schedule and add （or delete） process resource transparently.The manager can schedule system resources to support parallel data processing among crypto chips in crypto modules.These designs also implement the extensible resource management of crypto cluster server.
