可信计算的研究与发展

Research and Development of Trusted Computing

传统信息安全系统以防外部入侵为主,与现今信息安全的主要威胁来自内部的实际不符合。可信计算由内部防护,从根源上防止各种安全隐患问题的发生,成为信息安全研究的一个新阶段。其主要思想是将安全芯片嵌入到计算机硬件设备平台中,利用平台的安全特性来保障安全。概述了可信计算的研究背景及其基本概念,分析了国内外发展现状和可信计算对产业界带来的影响,最后针对可信计算的发展现状进行了展望以及对可信计算的重点研究问题与研究方法进行了思考。

Traditional system of information security focuses on external invasion,which can not solve the practical situation of that the main menace in current information security systems comes from the inside.Trusted computing is to start from the within,from the courses of the problem to prevent the occurrence of a variety of security risks,making it become the new stage of information security.Its main idea is that the whole system＇s security is greatly improved via bringing security chip architecture in the computing hardware platform.In this paper,the background and basic concepts of trusted computing are introduced in detail,and its development both at home and abroad,and effects on industrial circles are presented.At last,a prospect about the development of trusted computing is made and the key research issues and research methods are given.
