    • An apparatus and a method for offering security are provided to recognize whether a security program is protected or the security program is transformed, thereby inspecting whether virus infection occurs between general domains where the security program is installed and conducting equivalent treatment for the virus infection. A virtual machine monitor(110) performs communications between operating systems equipped in a plurality of domains. Security programs(180a,180b) are equipped in one of the domains through the communications, and carry out virus scanning and treatment of the corresponding domain or another domain on the operating systems. The domain comprises as follows. A general domain has the security program. A secure domain(130) has a security program administration module for installing or updating the security program by using security program information.
    • 提供一种用于提供安全性的装置和方法,以识别安全程序是否被保护或安全程序是否被转换,从而检查是否在安装安全程序的一般域之间发生病毒感染并对病毒感染进行等效的处理。 虚拟机监视器(110)执行装备在多个域中的操作系统之间的通信。 安全程序(180a,180b)通过通信装备在其中一个域中,并对操作系统上的相应域或另一个域进行病毒扫描和处理。 域包括如下。 一般域具有安全程序。 安全域(130)具有安全程序管理模块,用于通过使用安全程序信息安装或更新安全程序。

    • A method and a device for processing access to a disk block are provided to improve performance by sharing a cache between OS(Operating System) domains through memory access control in a VMM(Virtual Monitor Machine) environment without copying data and prevent data collision by performing access control for a disk drive in a device domain. A device domain(210) receives an access request to a disk block from one OS domain(200,220), determines permission of the access request to the disk block by referring to a block table(212), and processes disk block access of the OS domain depending on a determination result. The device domain includes the block table including more than one of a lock type, a lock holder, a home node, and a page address of the disk block. The device domain requests updating a page table of the OS domain to a VMM(230) to share a page of the disk block and returns the page address shared by updating the page block to the OS domain when the disk block is cached to other OS domain. The device domain accesses a disk drive(240) and enables the disk drive to copy data of the data block to the page of the OS domain when the disk block is not cached to other OS domain.
    • 提供用于处理对磁盘块的访问的方法和设备,以通过在VMM(虚拟监视器机器)环境中的存储器访问控制在OS(操作系统)域之间共享高速缓存来提高性能,而不复制数据并通过执行 设备域中磁盘驱动器的访问控制。 设备域(210)从一个OS域(200,220)接收对磁盘块的访问请求,通过参考块表(212)来确定对该磁盘块的访问请求的许可,并且处理OS的磁盘块访问 域取决于确定结果。 设备域包括包含锁定类型,锁定保持器,家庭节点和磁盘块的页面地址中的多个的块表。 设备域请求将OS域的页表更新到VMM(230),以共享磁盘块的页面,并且当磁盘块被缓存到其他操作系统时,将通过更新页面块的页面块返回到OS域 域。 当磁盘块未被缓存到其他OS域时,设备域访问磁盘驱动器(240)并使磁盘驱动器可以将数据块的数据复制到OS域的页面。

    • A method and an apparatus for allocating a free space of a disk for storing a file are provided to reduce a search time by allocating the free space of the disk according to sizes of empty spaces. A first algorithm process is performed to execute a first algorithm to allocate empty spaces positioned at a constant distance from a reference point(210). A first decision process is performed to decide whether an allocating process of the empty spaces for the object data is completed by using the first algorithm(220). A second algorithm process is performed to execute a second algorithm to allocate large-sized empty spaces in the first place(230). A second decision process is performed to decide whether the allocating process of the empty spaces for the object data is completed by using the second algorithm(240). A third decision process is performed to decide a remaining state of the empty spaces(250).
    • 提供一种用于分配用于存储文件的盘的可用空间的方法和装置,以通过根据空格的大小分配盘的可用空间来减少搜索时间。 执行第一算法处理以执行第一算法以分配与参考点(210)恒定距离定位的空白空间。 执行第一决定处理以通过使用第一算法(220)来确定对象数据的空白空间的分配处理是否完成。 执行第二算法处理以执行第二算法以首先分配大尺寸空格(230)。 执行第二判定处理,以通过使用第二算法(240)来确定对象数据的空白空间的分配处理是否完成。 执行第三决定处理以确定空白空间的剩余状态(250)。
