Abstract: Provided are a smart card service method and an apparatus for performing the same. The smart card service method includes receiving a certificate generation request from a terminal, transmitting the certificate generation request to an authentication processing device, and storing credential information with respect to the generated certificate in a virtual machine associated with the terminal in response to a certificate generation success message provided from the authentication processing device. Thus, it is possible to reduce costs in accordance with manufacturing smart card hardware, and support smart card services in a more enhanced security environment.

Abstract: Disclosed herein is a method of preparing a deer bone extract in which deer bones are subjected to extraction at normal pressure and extraction under pressure to minimize decomposition of deer bone-derived gangliosides by heat and to increase protein extraction yield.

Abstract: An automatic para-virtualization apparatus of an OS kernel is provided. The automatic para-virtualization apparatus includes a kernel profiler that detects profile information from a native OS kernel, and a virtualization unit that automatically generates a para-virtualized OS kernel that operates on a para-virtualization virtual machine monitor by combining the native OS kernel and the profile information.

Abstract: Disclosed herein is a method and apparatus for supporting virtualization. In the method, conversion of source code of a loadable module is initiated. A virtualization-sensitive instruction is searched for during the conversion of the source code. If the virtualization-sensitive instruction has been found, a virtualization-sensitive instruction table is generated based on the found virtualization-sensitive instruction. The virtualization-sensitive instruction is substituted with an instruction recognizable in a privileged mode, based on the generated virtualization-sensitive instruction table. The loadable module is loaded and executed in a kernel. Accordingly, the present invention supports virtualization, thus minimizing overhead occurring in full virtualization, and guaranteeing the high performance provided by para-virtualization without modifying a source.

Abstract: An OS switching method for switching an OS within several seconds in an information processing system is provided. In the information processing system which includes a processor, a main memory, a nonvolatile memory, and a plurality of input/output apparatuses, an OS switcher is executed when power is applied to the information processing system. When a first OS acquires an OS switch command that indicates a switch to a second OS while the first OS is activated and running, the first OS stores identification information of the second OS and information indicating an OS switch in the nonvolatile memory, and performs STR. The OS switcher switches an OS from the first OS to the second OS after the STR is completed. Accordingly, in the system, one OS can be quickly switched to another OS within several seconds, and a previous working environment can be maintained.

Abstract: Disclosed herein are an apparatus and method for virtualizing Input/Output (I/O) devices. The apparatus includes a hardware device control unit, a guest Operating System (OS) unit, a virtual machine monitor unit, and a host OS unit. The hardware device control unit controls the I/O devices of a terminal. The guest OS unit runs a guest OS via a virtual machine. The virtual machine monitor unit includes shared memory and an event channel, stores an instruction and data, and transfers the stored instruction and the data to a host OS. The host OS unit performs the operation of assigning the shared memory to the virtual machine monitor unit, the operation of generating the event channel, and an operation corresponding to the I/O instruction, stores the results of performance of the operations, and performs control so that the results of the performance of the operations are sent to the guest OS unit.
