Research and Development of Trusted Computing

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.
