Abstract: A substitute box includes a target input terminal, an obfuscation input terminal, a first output terminal and a second output terminal. The target input terminal is configured to receive a target input data. The obfuscation input terminal is configured to receive an obfuscation input data unrelated to a plaintext. The first output terminal is configured to output a first output data. The second output terminal is configured to output a second output data associated with the first output data. The first output data and the second output data are generated according to both the target input data and the obfuscation input data.

Abstract: A computer system and a control method thereof are described. The computer system includes a first memory, a second memory, and a control module. The first memory is configured to store a Basic Input Output System (BIOS) program. The second memory includes a first memory block and a second memory block. The control module, when a scan function is initiated, is configured to execute the BIOS program to generate a first restart program, wherein the control module is configured to store the first restart program into the first memory block and scan the second memory block, and stop using an abnormal cell in the second memory block.

Abstract: An operating system switching method for use in an electronic device is provided. The method includes the steps of: determining whether the first operating system receives an operating system switching command at time t1; storing first status data to a volatile memory and a non-volatile memory when a first operating system enters a non-operating state from an operating state based on the operating system switching command; writing second status data stored in the non-volatile memory to the volatile memory; and controlling the second operating system to enter the operating state from the non-operating state and recover to the operating status at time t2 based on the second status data stored in the volatile memory, wherein time t2 is earlier than time t1.

Abstract: One embodiment relates to a computer-implemented method for protecting a removable storage device from malware on a computer apparatus. An indication is received that the removable storage device has been connected to the computer apparatus, wherein the removable storage device is partitioned into a CD-ROM partition and a user partition. An anti-virus module stored in the CD-ROM partition on the removable storage device is automatically executed upon connecting the removable storage device to a computer apparatus. Other embodiments, aspects and features may also be disclosed.

Abstract: A tool set includes a pivot unit extending in a first direction, and at least two tool units, each of which includes two tool members attached rotatably to the pivot unit. Each of the tool members includes a tool head, a tool body connected to the tool head and extending in a second direction transverse to the first direction, and a connecting head connected to the tool body and having the pivot unit extending rotatably therethrough. The tool members of each of the tool units are disposed adjacent to each other such that the tool bodies of the tool members are disposed side by side in a third direction transverse to the first and second directions, and such that the connecting heads of the tool members are disposed side by side in the first direction.

Abstract: A method of detecting and configuring an internet connection of a router includes verifying that the router is connected to a physical internet connection, transmitting a Dynamic Host Configuration Protocol (DHCP) request through the physical internet connection, configuring the router to use a DHCP internet connection if a response is received from a DHCP server, transmitting a Point-to-Point Protocol over Ethernet (PPPoE) request through the physical internet connection, configuring the router to use a PPPoE internet connection if a response is received from a PPPoE server, and configuring the router to use a fixed Internet Protocol (IP) address internet connection if a response is not received from either the DHCP server or the PPPoE server.
