Design of U Disk Remote Monitoring System in Trusted Computing Environment

摘要

To solve the problem that the information of removable storage device can be easily disclosed and not be monitored effectively, a scheme of U disk remote monitoring system in trusted computing environment is proposed, which uses dual authentication technology to ensure that the users and removable storage device double-way reliable, it stores the cipher text of its internal documents to avoid being disclosed. In the process of the authentication, using DAA (Direct Anonymous Attestation) technology can protect the identity of the trusted computers inside LAN. As is shown in the experimental results, with the same computing environment, the encryption and decryption speed of using 160-bit elliptic curve encryption technology is 5-8 times faster than using 1024-bit RSA, based on this result, a new scheme is designed with elliptic curve encryption technology, which can ensure the performance efficiency been improved definitely. Demonstrated by analyzing solution, the process of this new scheme is simple, its safety is powerful and its implementation efficiency is very high.
