Abstract:
An exemplary apparatus includes one or more processors; memory; circuitry configured to hash a value associated with core root of trust measurement code and system management code; store the hash in a secure register; load an operating system; validate a certificate associated with the core root of trust measurement code and validate a certificate associated with the system management code; based on the validated certificates, provide an expected hash associated with the core root of trust measurement code and the system management code; decide if the expected hash matches the hash stored in the register; and, if the expected hash matches the hash stored in the register, commence a dynamic root of trust measurement session. Various other apparatuses, systems, methods, etc., are also disclosed.
Abstract:
Computer implemented method, system and computer program product for controlling software entitlement. A computer implemented method for controlling software entitlement includes receiving a request to install a software item on a designated machine. A determination is made if the designated machine is of a machine type authorized for installation of the software item. If the designated machine is of a machine type authorized for installation of the software item, a determination is made, using stored configuration data, if at least one additional criterion specified for entitlement to install the software item on the designated machine is satisfied using stored configuration data. If the at least one additional criterion specified for entitlement to install the software item on the designated machine is satisfied, installation of the software item on the designated machine is enabled in accordance with the at least one additional criterion.
Abstract:
A method for protecting Security Accounts Manager (SAM) files within a Windows® operating system is disclosed. A SAM file encryption key is generated by encrypting a SAM file via a syskey utility provided within the Windows® operating system. The SAM file encryption key is then stored in a virtual floppy disk by selecting an option to store SAM file encryption key to a floppy disk under the syskey utility. A blob is generated by performing a Trusted Platform Module (TPM) Seal command against the SAM file encryption key along with a value stored in a Performance Control Register and a TPM Storage Root Key. The blob is stored in a non-volatile storage area of a computer.
Abstract:
A method for preventing unauthorized modifications to a rental computer system is disclosed. During boot up of the rental computer system, a determination is made whether or not a time-day card is bound to the rental computer system. If the time-day card is bound to the rental computer system, another determination is made whether or not a time/date value on the time-day card is less than a secure time/date value stored in a secure storage location during the most recent power down. If the time/date value on the time-day card is not less than the secure time/date value, yet another determination is made whether or not the secure time/date value is less than an end time/date rental value. If the secure time/date value is less than the end time/date rental value, the rental computer system continues to boot.
Abstract:
A method and system are disclosed in which a management module (MM) designates an idle blade in a client blade farm to be an “administrative blade” that has administrator access to the virtual images of all users. The MM identifies when a particular user image is, or is not, in use and conveys this information to the administrative blade. The administrative blade performs virus scans, backups, defrags, patch installs, software upgrades, and other such maintenance functions on user images when they are inactive, thereby eliminating the performance impact to active users.
Abstract:
An apparatus, system, and method are disclosed for deduplicating storage cache data. A storage cache partition table has at least one entry associating a specified storage address range with one or more specified storage partitions. A deduplication module creates an entry in the storage cache partition table wherein the specified storage partitions contain identical data to one another within the specified storage address range thus requiring only one copy of the identical data to be cached in a storage cache. A read module accepts a storage address within a storage partition of a storage subsystem, to locate an entry wherein the specified storage address range contains the storage address, and to determine whether the storage partition is among the one or more specified storage partitions if such an entry is found.
Abstract:
A technique for identifying a user of a device includes receiving a tracking mechanism trigger and capturing (e.g., periodically) identifying information on the user of the device in response to the trigger.
Abstract:
A technique for preventing damage to a portable device includes detecting movement of a portable device and determining whether a port of the portable device is attached to an external device. When the external device is attached to the port, a notification is provided to a user of the portable device that the external device requires detachment from the portable device (e.g., assuming that the notification is not masked).
Abstract:
An apparatus, system, and method are disclosed for remotely accessing a shared password. A storage module stores identifiers, passwords, and keys within a secure key structure of a client. The passwords and keys include a shared password encrypted with a shared password key that is encrypted with a service structure key. The storage module also stores the service structure key encrypted with a key derived from a service password on a trusted server. An input/output module accesses the trusted server from the client with a prospective service password and receives the encrypted service structure key from the trusted server if a hash of the prospective service password is equivalent to the service password. An encryption module may decrypt the service structure key with the prospective service password, the shared password key with the service structure key, and the shared password with the shared password key.
Abstract:
Method and apparatus for enabling applications on security processors of computer systems. In one aspect, a security processor apparatus includes a processor and a memory coupled to the processor and operative to store a secure table. The secure table stores different certified endorsement keys and different values, each value associated with one of the endorsement keys. Each stored value is derived from a different application that is certified by the associated endorsement key to be executed on the processor.
