Abstract:
Disclosed are a smart card service method and a device executing the same. The smart card service method includes the steps of receiving a certificate generation request from a terminal; transmitting the certificate generation request to an authentication processing unit; and storing credential information of the certificate generated in a virtual machine related to the terminal to correspond to a certificate generation success message provided from the authentication processing unit. Accordingly, the invention reduces manufacturing costs of smart card hardware while supporting the smart card service in a more secure environment. [Reference numerals] (100) Smart terminal; (110) Application; (130) Terminal interface unit; (200) Cloud; (211) Smart card virtual machine; (250) Security/authentication interface unit; (300) Security/authentication management device
Abstract:
The present invention relates to a virtualization support method and a device thereof. A virtualization support method given in the present invention includes a step of starting source code transformation of a loadable module; a step of searching for a virtualization sensitive command; a step of, if any virtualization sensitive command is found, generating a virtualization sensitive command table based on the found virtualization sensitive command; a step of converting the virtualization sensitive command to a command readable in a privileged mode based on the virtualization sensitive command table; and a step of running the loadable module by mounting the module in a kernel. By doing so, the overhead cost due to full-virtualization can be minimized and high performance in semi-virtualization can be guaranteed without source modification. [Reference numerals] (AA) START;(BB) END;(S201) Convert source code;(S202) Identify a virtualization sensitive command?;(S203) Generate a virtualization sensitive command table;(S204) Switch to a privileged mode and substitute the command;(S205) Run a kernel module
Abstract:
PURPOSE: An input/output device virtualization device using a share memory in a host-based terminal virtualization environment and a method thereof are provided to easily virtualize various input/output devices by processing an input/output request through an event channel and the share memory of a VMM(Virtual Machine Monitor). CONSTITUTION: A hardware device control unit controls an input/output device and a guest OS unit(200) operates a guest OS for executing an application program VMs(210-230). A VMM(300) includes a share memory(310) for input/output data delivery and an event channel(320) for event channel delivery. If an input/output request signal is received from the guest OS unit, the VMM stores data and commands corresponding to the input/output request signal in the share memory and delivers the data and the commands to a host OS(100) through the event channel. [Reference numerals] (100) Host OS; (150,160,170) Original device driver; (200) Guest OS unit; (210,220,230,120,130,140) Virtual device driver; (300) Virtual machine monitor; (310) Share memory; (320) Event channel; (400) Hardware device; (410,420,430) Input and output driver
Abstract:
PURPOSE: A virtualization based physical system and a resource management method thereof are provided to request resource control after a virtual machine confirms the necessity of the resource control. CONSTITUTION: A plurality of virtual machines(220_1~220_m) monitors the state of resource utilization. A plurality of virtual machines decides whether control is necessary for the state of resource utilization or not. A plurality of virtual machines requests the control. A control machine(210) includes a monitor unit and a resource management unit. The control machine adjusts the state of resource utilization of the corresponding virtual machine in response to the request of each virtual machine.

사용자의 임의 지점 재생 요구에 대응하여 지속적인 스트리밍 서비스를 제공할 수 있는 인터넷 기반 멀티미디어 스트리밍 서비스를 위한 동적 선반입 시스템은 다수의 멀티미디어 스트리밍 원본 데이터가 저장된 광역 서버와, 광역 서버와 사용자간에 네트워크 상태를 토대로 로컬 영역에 저장될 원본 데이터의 비율을 결정하고, 비율에 따라 로컬 영역 중에서 상기 원본 데이터가 저장될 영역을 다수의 구분 영역으로 분할한 후에 상기 각각의 구분 영역을 기록 영역과 비기록 영역으로 나누며, 각각의 기록 영역에 대응되는 데이터를 상기 원본 데이터에서 추출하여 각각의 기록 영역에 저장하는 지역 서버를 포함한다. 상기와 같은 지역 서버는 사용자의 임의 지점 재생 요구에 응답하여 재생 위치에 데이터가 존재하는지를 판단한 후 판단결과 데이터가 존재하지 않을 때 상기 재생 위치에서 가까운 기록 영역을 검색하고, 검색된 기록 영역의 데이터를 사용자에게 전송한 후에 원본 데이터의 나머지 부분을 상기 광역 서버로부터 수신하여 사용자에게 전송한다.
