Research and Implementation of a Trusted Removable USB Flash Device

摘要

In this paper we present the research and implementation of TRFD, a Trusted Removable USB Flash Device which can resist various attacks. TRFD is an independent system which would authenticate the user and host before data access. All the data secure processing of TRFD, such as encrypting, signing, are performed inside the device, so TRFD can protect the data against host hacking. The evaluation of our prototype shows that TRFD can solve some security issues of removable storages indeed.
