Design And Implementation Of File Migration System Based On Trusted Computing

With the rapid development of computer network and the increasing of information, more and more people pay their attention to the File migration system that is used in daily life and office process. The available file migration system mostly depends on the signature and encrypted software. As a kind of program, the software can be infected by malicious code, so it may be What-you-see-isn't-what-you-sign or the problem of the invalid encryption. More than that, because the ID or integrality isn't tested before the migration, the file migrates to illegal platform that has been broken by malicious code, which may cause the loss, and threaten to security.Firstly, a kind of file migration system model based on trusted computing was proposed in this paper, with the analysis of the security requirement of file migration system to the security problem of file migration system. The system composition and function of the model have been described in detail.Secondly, the idea of Trust negotiation has been proposed to the problem that the platform isn't been verify, before the migration. Remote attestation protocol based on property has been designed, and a kind of method of applying property certificate has been proposed.And then, key migration protocol has been signed for the problem that the encrypted file migrates from one trusted platform to another.In the end, the trusted terminal software architecture has been signed in trusted file migration system based on the system model. The Remote attestation protocol and key migration protocol program based on property and trusted file migration system terminal software has been compiled and tested.
