  • Patent number: 9483278
    Abstract: The present invention protects a memory image of an OS in a sleep state. A CPU executes a first OS or a second OS while switching there between. The first OS is loaded into a main memory, and the second OS is loaded into an auxiliary memory. The auxiliary memory may be connected to a chipset through a PCIe interface. The main memory and the auxiliary memory are configured such that, when one is in an active state where the right of access to the CPU is obtained, the other makes a transition to the sleep state where there is no right of access to the CPU while maintaining the memory image. In order to prevent one OS in the active state from accessing the main memory or the auxiliary memory in which the memory image of the other OS in the sleep state is stored, the BIOS may set a corresponding controller to disabled during a POST.

  • Publication number: 20160012233
    Abstract: Provided is a technique to enhance security of a computer in a multi-OS operating environment. A memory image of a primary OS is in an active state, and a memory image of a secondary OS is in a non-active state. When switching is performed from the primary OS to the secondary OS, a runtime image is created, and a digest P is calculated and encrypted (C). When switching is performed from the secondary OS to the primary OS, a digest of the stopped runtime image is calculated. Only when comparison between the decrypted digest P and the calculated digest shows agreement, is switching of the primary OS allowed.

  • Publication number: 20160004539
    Abstract: Provided is a manner of switching between the operating environment of a primary OS and the operating environment of a secondary OS. In certain embodiments, a HDD keeps a runtime image of the secondary OS generated in a system memory. A DMA space for allowing the secondary OS to operate is formed in a physical address space where a memory image of the primary OS is active. The runtime image of the secondary OS is transferred to the DMA space. The operation of the memory image of the primary OS is stopped and the runtime image of the secondary OS is executed in the DMA space. Before activating the memory image of the primary OS, the runtime image of the secondary OS is saved to the HDD again.

  • Publication number: 20140317392
    Abstract: The present invention provides a method of easily managing two or more OSs. A host OS, a guest OS, and a virtualization module are loaded into a primary physical address area of a main memory. The guest OS is executed in a virtual environment in a primary physical address area. A memory image of the guest OS loaded in the primary physical address area is copied to a secondary physical address area. The right of access to a processor is transferred to the guest OS copied in the secondary physical address area to execute the guest OS in a physical environment.

  • Patent number: 8756667
    Abstract: In the context of computer systems, the generation of preboot passwords at a server instead of at a client. Preferably, preboot passwords generated at the server are distributed to the client, and a process is offered whereby a user can establish his/her own proxy, not known to the server, that can be used to release the stored passwords to the client hardware. Since the passwords are generated at the server, management of the passwords is greatly facilitated since they are generated at the site where they are stored. This also makes it easy to implement management features such as a group policy, since the password generation software will be able to make logical connections between users and hardware.

  • Patent number: 8745414
    Abstract: Unsecure system software and secure system software on the same computer system is switched between. A computer system includes one or more processors, which may not have any built-in security features, memory, and firmware. The memory stores secure system software and unsecure system software. In response to receiving a user signal, the firmware switches from the unsecure system software running on the processors to the secure system software running on the processors (and back again). While the unsecure system software is running, the secure system software is protected from tampering by the unsecure system software.

  • Patent number: 8543803
    Abstract: An apparatus, system, and method are disclosed for suspend-resume scheduling in conjunction with an operation requiring a suspend-resume cycle of a computer 200, including updating, for purposes of system configuration management, a non-volatile memory 506, such as an electrically erasable programmable read-only memory (“EEPROM”) 702. A control module 402 sends 806 a request to update the EEPROM 702. A suspend module 404 suspends 818 an operating system 204. A standby module 406 prepares 904 the computer 200 to enter a standby state, estimates 914 a sufficient amount of time to enter the standby state, places 916 the estimate into an alarm register 608, and then enters 918 the standby state. An update module 308 exits 1004 the standby state in response to an alarm signal 612, receives the request if present 1008, writes 1012 the EEPROM 702 with the updated information, and resumes 1018 the operating system 204.

  • Patent number: 8347348
    Abstract: An apparatus, system, and method are disclosed for pre-boot policy modification. A key module exchanges a key with a server in a secure environment. A communication module receives a policy encoded with the key. A decode module decodes the encoded policy using the key and saves the policy setting prior to booting an operating system on the computer. An update module boots the computer using the policy.

  • Patent number: 8245054
    Abstract: An information processing apparatus includes a storage device having an access-restricted area accessible if the password is properly authenticated and an access-unrestricted area accessible regardless of whether or not the password is authenticated. The information processing apparatus allows a password to be registered in a registration server beforehand, prompts a user to enter the password when accessing the access-restricted area and, if the password is not entered, reads from the access-unrestricted area a password retrieval program for retrieving the password from the registration server, activates and executes the password retrieval program to retrieve the password from the registration server, and causes the storage device to authenticate the retrieved password to place the access-restricted area in an accessible state.

  • Patent number: 8166540
    Abstract: A system, apparatus, and methods are disclosed for aligning a stored scancode sequence that corresponds to a hardware password, with a password input device type such as a current keyboard type. Aligning the stored scancode sequence with the password input device type enables successful validation of a hardware password despite a change in a password input device type or inadvertent corruption of a non-volatile memory used for storing the scancode sequence such as non-volatile memory that stores BIOS information for a computing device.

  • Patent number: 8156331
    Abstract: Methods and apparatus are provided for securely inputting highly confidential information, exchanging the information via a network, and securely reflecting the information in a computer, without the information being stolen by malicious software. Upon a transfer of encrypted information from a server to a computer, the transferred information is stored in a memory of the computer and the computer is switched to a suspended state and immediately thereafter returns to the previous state to be shifted to under the control of a BIOS. The information stored in the memory is decrypted and processed there. Processing information generated based on the processed information is then encrypted and it is transferred to the server after the computer is switched to under the control of the operating system.
