汉字字形结构式压缩方法的研究和实现

计算机科学 2003年第5期30卷 78-81页

作者：高锐智华成英清华大学自动化系北京100084

Because outputing chinese font in computer is limited in complicated building process and mass storage, wepropose a structural-based compression scheme. The approach bases on the stroke-assembled shape character of chi-nese font, extracts stroke outlines and clusters these outlines to create stroke template. This paper also introducesfont structural compression software developed by us, explains the process of our structural-based compressionscheme.

This paper proposes a configurable secure gateway architecture which allows the system administrators to dynamically configure the security mechanisms upon deployment or during the run-time. Rather than allowing the system administrators to turn on or off individual security mechanisms, the proposed architecture allows the administrators to configure the gateway based on the security threats to be overcome. The current common architecture leads to tremendous administration overhead and increases the chance of misconfiguration vulnerability. We propose a novel software architecture to aid the product designers to avoid the misconfiguration vulnerability and the end-users to ease the administration overhead. The software architecture makes use of the threats to the gateways and the occurrence relation between the threats to configure the security software components on the gateways. With the software architecture, the end-users can focus on determining the desired security features rather than the software configuration. Moreover, the architecture allows the product designers or security service to incrementally revise the software configuration when new threats appear.

Security-mediated certificateless （SMC） signature not only addresses the issues about instantaneous revocation of keys in certificateless signature （CLS） but also resolves the key escrow problem in identity-based signature （IBS）. In this paper, based on Waters’ signature scheme [15], Paterson et al.’s IBS scheme [13] and Xiong et al.’s CLS scheme [18], we propose a SMC signature scheme which is secure against malicious-but-passive KGC attack in the standard model.

绝大多数嵌入式实时系统仅配置了必不可少的资源,任务间抢占行为导致的额外开销严重影响着系统的性能。通过分析周期性任务的调度过程,得出在确保任务不错过截止期条件下,各个任务在就绪队列中可等待的最长期限计算公式,并根据公式推导出任务满足截止期的最后抢占时刻等属性,从而定量地刻画了周期性任务抢占行为发生的必要条件,提出了一套对周期性任务的就绪队列进行微调度的抢占模型,通过改变抢占关系来减少抢占次数、优化实时系统性能。本文最后通过实验验证了该微调度的抢占模型不仅有效地减少抢占次数,同时对于静态优先级调度策略如RM,能有效地提高处理器的可调度利用率。
