Research and Design for USB and Network Cards Encryption Interface Card

This paper propose an interface card program to solve the LAN security questions, which aims at coping the key information as a medium by U disk and launch malicious attacks, disclosing information, as well as transferring network information or launch malicious attacks through LAN and so on. The experiment shows that the interface card can enable the PC data transmission in the LAN and U disk data transmission is transparent encrypted and decrypted. It can simultaneously ensure that the PC´s data transmission in the LAN and U disk´s data transmission is security.
