Abstract


The rapid development of information security technology has brought the convenience and happiness to people, but also has brought a series of security problems.Facing with the treats of rampant viruses and trojanses,it is very important to protect information’s integrity, privacy and reliability. The traditional protection technologies are focused on defense and they are based on software, so that sorts of measures becomes more does more complex, but it couldn’t gurantee the safety. Trusted computing technology is combined with software and hardware,it depends on a hardware module which provides the fuctions of cryptographic algorithms and key management to make the computer system more reliability and safety.This article comes from National Natural Science Foundation Project-"The Research of Credible Visit Strategy Based On Multinuclear I/O resouces".According to the trusted computing technology and TCM interface standard,I proposed a kind of Trusted computing platform framework which is based on Embedded Trust Secutity Module(ETSM).We took the core content of trusted computing-key management thoughts as the instruction,put forward the architecture of key management based on ETSM.I has designed and realized the basic fuctions including algorithm implemented, key generation, dual-port key cache management and external key storage etc.Meanwhile make use of IC card and secret sharing theory to design and realize the main key’s management.In addition,I develop an ETSM trusted platform application system,the system contains four modules:files’key management, including key’s creation、registration and query;the module of file encryption,provide security encrypt-decrypt service for user;the module of encrypt network,which can filter sensitive data or encryption;the module of trusted U disk,which can provide transparent file encryption and decryption.After the tests,it proves that the ETSM trusted platform’s functions of key management and application system can running smoothly,so that it achieves the expected effect.
