| 20090055918 | METHOD OF MUTUALLY AUTHENTICATING BETWEEN SOFTWARE MOBILITY DEVICE AND LOCAL HOST AND A METHOD OF FORMING INPUT/OUTPUT (I/O) CHANNEL - A method of mutually authenticating between a local host and a software mobility device including an operating system virtualization layer, and a method of forming an input/output (I/O) channel. The method of authenticating a local host in the software mobility device includes requesting a certificate from the local host in which an integrity value of the local host is stored, and receiving the certificate from the local host; receiving an integrity value measured in the local host and comparing the measured integrity value with the integrity value included in the certificate to verify the local host; and when the local host is verified, encrypting a security profile of the software mobility device and transmitting the encrypted security profile to the local host so as to provide secure communication between the local host and the software mobility device. | 02-26-2009 |
| 20090216916 | METHOD AND APPARATUS FOR INPUTTING/OUTPUTTING DATA USING VIRTUALIZATION TECHNIQUE - A method and apparatus for inputting and outputting data by using a virtualization technique are provided. The method includes generating a virtual operating system (OS) for the external device, which is connected to a host, based on OS information stored in the external device, setting a partial area of a storage of the host as virtual storage for the external device, and storing the data in the virtual storage or a memory of the external device in response to a request for inputting and outputting the data from the virtual OS. | 08-27-2009 |
| 20090241110 | VIRTUAL ENVIRONMENT SYSTEM AND METHOD FOR OPERATING THE SAME - A virtual environment system and a method of operating the same, the virtual environment system including: a virtual operating system (OS) unit to operate a virtual OS installed in a mobile storage medium in a host OS installed in a host computer, to attach a virtual resource included in the virtual OS to the host OS, and to perform arbitration so that a virtual process operated in the virtual OS uses the virtual resource; and a user interface unit to provide a virtual desktop screen so that a user can use the virtual process in the virtual environment provided by the virtual OS. | 09-24-2009 |
| 20090271605 | METHOD AND APPARATUS FOR RESTORING SYSTEM USING VIRTUALIZATION - A method and apparatus to restore a system using virtualization, the method including: if a system restoration at a target restoration time point from among at least one restoration time points is requested, generating a virtualization layer; if a use of a system is requested by an application layer, accessing the target restoration time point using the virtualization layer; and performing a system restoration at the accessed target restoration time point. | 10-29-2009 |
| 20100138832 | APPARATUS AND METHOD FOR PROVIDING SERVICES USING A VIRTUAL OPERATING SYSTEM - Provided are an apparatus and method for providing services using a virtual operating system (OS). The apparatus classifies virtual resources into a plurality of mutually exclusive regions and manages the virtual resources based on the provides services regions. The plurality of provides services regions include a virtual region whose resources are stored in and used on an external storage, and an overlay region whose resources refer to host resources. The apparatus uses the region information for virtual resources and a list of resources accessed for each application process to manage the virtual resources. | 06-03-2010 |
| 20100325191 | MANAGEMENT SERVER AND METHOD FOR PROVIDING CLOUD COMPUTING SERVICE - A management server and method for providing a cloud computing service at high speed and reasonable cost, are provided. The management server provides a virtual machine to a client as a computing resource. The virtual machine is multiplexed by operating multiple virtual devices on a single virtual machine. Accordingly, demand for computing resources may be predicted in advance and may be provided to a user more efficiently. | 12-23-2010 |
| 20100325199 | CLIENT, BROKERAGE SERVER AND METHOD FOR PROVIDING CLOUD STORAGE - A system for providing resources of a cloud infrastructure is provided. In the system, a client terminal may dynamically span its storage to heterogeneous cloud storages as necessary. A client determines, when receiving a file access request from an application, whether to process the file access request as a local file access request for access to a local storage of the client or as a cloud file access request for access to a cloud storage connected through the Internet. A brokerage server receives the file access request and supports the client by brokering a connection to a cloud infrastructure in response to the file access request. | 12-23-2010 |
| 20110087726 | CLOUD SERVER, CLIENT TERMINAL, DEVICE, AND METHOD OF OPERATING CLOUD SERVER AND CLIENT TERMINAL - A cloud computing system that allows a client terminal to make use of different types of devices using a cloud computing service of a cloud server, is provided. The cloud server retrieves a virtual device driver for a device using retrieval information received from the client terminal and installs the virtual device driver so that the client terminal may control the device. Although the client terminal does not support an information format which is supported by the device, the computing service allows information to be used by the client terminal. | 04-14-2011 |
