摘　　要：计算模式的变革发展,第三个时代——普适计算时代即将来临,它广阔的应用前景让其迅速成为研究的热点。而如何构造一个安全的普适计算环境,即如何能够安全地获得普适计算环境提供的方便快捷,成为普适计算发展应用道路上一个迫切需要解决的问题。本文从普适计算环境的特点入手,在对现有安全机制基于普适计算环境下的优缺点进行分析比较的基础上,探讨并提出了一套适应普适计算环境的改进式安全解决方案——SSPKI。th change and development of computing mode, the third computing era - Era of Ubiquitous Computing is coming. Concept of Ubiquitous Computing was brought forward, immediately lots of attentions and researches are attracted because of its widely-applied foreground. However, it is a critical problem at the development of Ubiquitous Computing, that how to instruct a safe Ubiquitous Computing Environment, and how to benefit safely from the convenience and expeditiousness provided by the U- biquitous Computing Environment. SSPKI, an improved security solution for Ubiquitous Computing Environment, is discussed and presented in this paper, based on analysis and comparison of advantages and disadvantages of existing security solutions for Ubiquitous Computing Environment.
