摘要
We developed a secure remote access system using a secure flash card for mobile workforce. The developed flash card has a tamper resistant module, which contains user authentication information and security keys. An authentication server and a client exchange their authentication information by using a key that is stored in the tamper resistant module of the flash card. Transactions between the flash card and the client are encrypted, and a processor encrypts and calculates the signature inside the tamper resistant module; thus, the system is highly secure. This remote access system also provides improved usability and increased information traceability.
