Abstract: PURPOSE: A keyboard security method and apparatus thereof are provided to prevent the leakage of personal information by transmitting the personal information based on an E2E(End to End) encryption method. CONSTITUTION: A server(100) installs and transmits a keyboard security program to a user terminal(200). The keyboard security program protects a key input process and registers a keyboard interrupt function in an interrupt vector table of the user terminal. The keyboard security program receives a start-end key combination signal. An encryption progress is executed for a user key inputted between the start-end key combination signals. The keyboard security program transmits the encrypted key input signal to the OS(Operating System) of the user terminal and cancels the registration of the keyboard security program.

Abstract: PURPOSE: A device controlling memory access in a virtualization system and a method thereof are provided to deny direct access for a memory area in a hypervisor without memory access permission of a memory management unit, thereby preventing access for a memory which a virtual machine(VM) in the hypervisor uses. CONSTITUTION: A hypervisor(10) is a virtual platform for executing a VM in a virtualization system at the same time. The hypervisor requests access for a memory area. A memory management unit(20) inspects occupation caused by the VM of the memory area corresponding to the access request. The memory management unit selectively approves memory access of the hypervisor corresponding to an inspection result. The hypervisor does not perform direct access for the memory area without permission of the memory management unit.

Abstract: PURPOSE: A user application memory protecting method is provided to efficiently protect a user application memory without degradation of a virtualized computer system by suing a mechanism which minimizes execution overhead. CONSTITUTION: An executing context is moved from an executing application to a guest OS(Operating System). A hypervisor removes access right to a memory area of the application. The executing context is moved from the guest OS to the application. The hypervisor modifies a page table of a virtual memory area of the application.

Abstract: PURPOSE: An apparatus for detecting and restoring an error of a device driver in a virtualization system and a method thereof are provided to detect an error of a driver VM in advance and suppress the error, thereby guaranteeing stability of a guest VM connected to the driver VM. CONSTITUTION: A guest VM(Virtual Machine)(30) executes at least one OS(Operating System). A driver VM(50) controls a hardware device(10) corresponding to the guest VM. An input/output information storing unit(61,62) stores information about a request and a response between the guest VM and the driver VM. A VMM(Virtual Machine Monitor)(20) virtualizes the hardware device to operate the guest VM. The VMM includes an error detecting monitor which periodically checks whether the driver VM has an error using information stored in the input/output information storing unit.

Abstract: PURPOSE: An apparatus and a method for mapping a data address in a NAND flash memory are provided to prevent unnecessary writing command due to medium. CONSTITUTION: A buffer(410) stores object data according to a writing command from first medium to second medium. The buffer generates data of a second operation unit which is larger than a first operation unit according to the command. An address map managing unit(420) stores an address map which maps a logical address of the data of the second operation unit to a physical address of the data of the first operation unit. A recording unit(430) records the data of the generated second operation unit.
