中文摘要：

Internet是计算机应用未来运行的主流平台,由于Internet环境的开放性和复杂性,传统的ACL、PKI技术已不能完全解决计算机应用的安全问题。以安全凭证为基础的信任管理技术和以历史交往经验及推荐经验为基础的信任评估技术,利用主体间的信任关系来解决开放协同环境中的信任问题,是目前Internet应用安全中的研究热点。基于此,对目前国内外的信任管理和信任评估技术的研究现状做了分析和总结,指出了它们的优势与不足,并探讨了In-ternet应用安全中信任问题的未来研究方向。

英文摘要：

Internet will be the main platform that the computer applications run on.Because of the openness and complicacy of internet,such traditional technology as ACL and PKI cannot completely solve the security problems of computer applications.The trust management technology based on security credentials and trust valuation technology on base of direct history experience and recommendation experience,which solve the trust problems of open and coordinated environment using the trust relations among entities,are the hot spots in security research of internet applications presently.Based on the status quo,an overview was made in this paper,in which the current research situation about trust mana-gement and trust valuation technology at home and abroad were analyzed and summarized.Subsequently,their advantage and weakness were pointed out,too.Finally,a prospect for further interesting research directions was proposed.
