系统资源受限环境下的证书解析方法研究

证书解析是证书应用的基础,目前已知的证书解析操作均运行于操作系统应用层。这种证书解析方法尽管具有较强的通用性,但代码复杂,占用系统资源较多。本文在研究证书格式的基础上,给出了一种适用于操作系统内核层、嵌入式系统等资源受限环境的解析方法,具有实现简单、占用资源少、运行速度快等特点。

Research of Certificate Parsing Method in Resource Restricted Environment

Certificate parsing is the foundation of certificate application. Presently, many of the known certificate parsers run on the OS application layer. This certificate parsing mode has good currency, but the code is complex and uses many system resources. Based on the analysis of certificate format, this paper gives a certificate parsing method which is applicable to environment restricted resource such as OS kernel and embedded system. This method has many advantages such as simple implementation, less system resource used, run- ning rapidness and so on.
