Abstract: A key storage device comprises a one-way receiving interface, a key calculation unit, and a one-way outputting interface. The key calculation unit includes a signature unit. The one-way receiving interface receives a transaction message of an external electronic device in a single direction. The signature unit encrypts the transaction message by a private key to generate a signature message. And, the one-way outputting interface transmits the signature message to the external electronic device in a single direction.

Abstract: This invention relates to a method for monitoring an executed process, more particularly for monitoring and tracing the execution of an application program on a window-based operating platform. The method of the present invention is first to collect the information of all executed processes, and then to build up a history table of all processes for finding out the main process of the execution of the application program. Next, according to the processes' handles saved in the history table, the monitoring method is to extract all sub-processes of the main process and construct the relation of all processes of the execution of the application program. Finally, hierarchically trace and monitor all executed processes of the application program.

Abstract: The present invention discloses a hardware data transfer integrity testing module and a hardware data transfer integrity testing method of parallel processing through the use of a ringbuffer. An interruption service program writes data into the ring buffer. When a main application program is processing the data, the interruption service program is still working to receive data, therefore saving the time for data transferring and testing. The buffer space required for the testing is also decreased.

Abstract: The invention relates to a method for pre-installing software program. First create a configuration file according to the demand of software programs in each destination disk drive. Then the server of a local area network creates an operating system image file and an application file package. The files are sent to the local area network station to pre-install the software. Using the method, the pre-installation of software program can be realized. Also, the user may select the programs freely without partitioning and formatting the hard disk. At the same time, the installation of software can be done in a large number of new machines automatically.

Abstract: A method for addressing the dynamic windows. The method uses a script interpreter, addressing identification module, and current windows layer description module combined together. When an operational unit is read from a script interpreter, it will generate a windows description. Input said windows description into a addressing identification module and hook the windows description by a current windows layer description module at the same time. The current windows layer description module will construct a windows description tree structure and the addressing identification module will calculate according to this tree structure. Complete the calculation and conclude a current windows identifier code to be operated by the tester.

Abstract: This invention discloses a method for backup and recovery of the long filename in the computer system (e.g., DOS) that not support the long filename. The technique of the backup operation of this invention is to read the file directory table (FDT) from the logic partition of the hard disk by calling the basic input output system (BIOS) function; then transfer the long filename and short filename items into long filename format and saving to a backup file. Alternatively, recovering the backup is to search the short filename of each directory and sub directory and obtaining the data in the back up file; then write the matched long filename back to the original FDT.

Abstract: A method for quickly formatting a disk is disclosed. It can save lots of time when a disk or a disk partition is formatted. The technique of this invention redirects the interrupt instruction of the BIOS to get the disk (or disk partition) information which includes the sector number, starting location and type thereof. According to the disk (or disk partition) type (FAT 16 or FAT 32), the section number of the file allocation table (FAT) is rearrange by a logical operation unit. Then write the boot record to the mapped location and clear the FAT and file directory to zero to accomplish disk formatting procedure.
