    • PURPOSE: A partition recovery method is provided to generate a virtual volume of the deleted partition in an evidence image and access the virtual volume. CONSTITUTION: A partition recovery apparatus reads partition recovery information(S710). The partition recovery apparatus recognizes a confirmed boot record as a boot record of a virtual volume(S720). The apparatus generates the structure of the virtual volume(S730). The apparatus performs the parsing of a file system(S740). The apparatus recovers a deleted file or a directory. The apparatus generates a tree structure of a file or a directory through a user interface module(S750).

    • A method for decrypting an encrypted file in real-time by using a file system is provided to enable an application program to use the encrypted file by decrypting the encrypted file in a memory through a file decryptor in real-time. An access request to the encrypted file is transferred to a file decryptor control program. The file decryptor control program transfers file information and key information to the file decryptor through an MFB(Mount File Block). A mounting/control program of the file decryptor registers the file information to an FIB(File Information Block) and a KIB(Key Information Block). The application program executing the encrypted file is executed by a mounting/control program. The application program reads and uses the encrypted file from the file decryptor. If the application program is terminated, the mounting/control program removes the encrypted file registered to the file decryptor.
    • 提供了通过使用文件系统来实时解密加密文件的方法,以使得应用程序能够通过文件解密器实时解密存储器中的加密文件来使用加密文件。 对加密文件的访问请求被传送到文件解密器控制程序。 文件解密器控制程序通过MFB(装载文件块)将文件信息和密钥信息传送到文件解密器。 文件解密器的安装/控制程序将文件信息注册到FIB(文件信息块)和KIB(密钥信息块)。 执行加密文件的应用程序由安装/控制程序执行。 应用程序从文件解密器中读取和使用加密文件。 如果应用程序被终止,则安装/控制程序将删除注册到文件解密器的加密文件。

    • PURPOSE: A switch with a lock function is provided to maintain a safe operation of an electronic equipment by preventing the projection or the insertion of a safety pin. CONSTITUTION: A switch with a lock function comprises a function setup portion(110), a safety pin(130), and a lock fixing portion(120). The function setup portion comprises a push switch for setting up a specific function. The safety pin operates the push switch. The lock fixing portion prevents the projection or insertion of the safety pin and fixes an operation status of the push switch. The lock fixing portion comprises a lock release button(123) and a spring(124). The lock release button is formed with a hole corresponding to a diameter of the safety pin. The spring prevents the projection or the insertion of the safety pin.
    • 目的:提供具有锁定功能的开关,通过防止安全销的突出或插入来保持电子设备的安全运行。 构成:具有锁定功能的开关包括功能设置部分(110),安全销(130)和锁定固定部分(120)。 功能设置部分包括用于设置特定功能的按钮开关。 安全销操作按钮开关。 锁定固定部分防止安全销的突出或插入并固定按钮开关的操作状态。 锁定固定部分包括锁定释放按钮(123)和弹簧(124)。 锁定释放按钮形成有与安全销的直径对应的孔。 弹簧防止安全销的突出或插入。

    • Provided is an apparatus for computing a T-function based Stream Cipher (TSC)-4 stream cipher. The apparatus includes: two T-function units; and a nonlinear filter for receiving bits output from the two T-function units and generating an 8-bit output sequence per clock. Each of the T-function units includes: a first register for storing an internal state value of the lower N bits; an N-bit internal state updater for updating the internal state value of the lower N-bits stored in the first register; an intermediate result register for storing an intermediate result value output from the N-bit internal state updater; a second register for storing an internal state value of the upper M bits; and an M-bit internal state updater for updating the internal state value of the upper M bits stored in the second register using the value stored in the intermediate result register.
    • 提供了一种用于计算基于T函数的流密码(TSC)-4流密码的装置。 该装置包括:两个T功能单元; 以及一个非线性滤波器,用于接收从两个T函数单元输出的比特,并且每个时钟产生一个8比特输出序列。 每个T功能单元包括:第一寄存器,用于存储较低N位的内部状态值; N比特内部状态更新器,用于更新存储在第一寄存器中的较低N比特的内部状态值; 中间结果寄存器,用于存储从N位内部状态更新器输出的中间结果值; 第二寄存器,用于存储高M位的内部状态值; 以及M位内部状态更新器,用于使用存储在中间结果寄存器中的值来更新存储在第二寄存器中的高M位的内部状态值。
