  • Publication number: 20070228164
    Abstract: The present invention uses a smart control module with HID descriptors to communicate with the host side in accordance with the standard HID communication protocol, so as to interact with the smart card, which can eliminate the need of installing a private driver from a particular manufacturer when installing its reader/writer. The driver of the HID device can be installed automatically upon installation of the operating system. The users can use the reader/writer easily without carrying a driver around. It is not necessary for the users to deal with upgraded versions of the driver, to consider compatibilities of drivers for different products, to confront usage risks of the operating system due to the driver, or to worry about contamination of the operating system resulted from the installation and uninstallation of the driver.

  • Publication number: 20070179891
    Abstract: The present invention relates to a secure transmission method and apparatus, particularly to a security control method for a data transmission process and a software protection apparatus using the same, where data transmitted between a computer running protected software and the software protection apparatus is in a cipher-text form, and thus a plain text does not appear in a communication line during the whole process. Moreover, since a random number is involved for scrambling and the data is encrypted, hence commands sent from the protected software to and those returned from the software protection apparatus change constantly even when the same command is sent from the sending end. In this way, it will be more difficult for a cracker to crack, thus securing the transmission of private confidential data.
