Systems, methods and products are described that provide predictive power state transitions for information handling devices. One aspect includes ascertaining a power state transitioning pattern of an information handling device; responsive to a power state transition to a first lower power state at the information handling device, performing an additional power state transition to automatically transition the information handling device to a second lower power state, the second lower power state being a lower power state relative to the first lower power state; and proactively resuming the information handling device to the first lower power state responsive to a timing threshold being met; wherein the timing threshold is determined based on the power state transitioning pattern ascertained. Other embodiments are described.

A method and system for binding a device to a planar is disclosed. According to the preferred embodiment of the method and system of the present invention, a programmable memory chip is provided on the planar and the device is detachably attached to the planar. The method and system further includes using the programmable memory chip to bind the device to the planar. Through the aspects of the present invention, the programmable memory chip transmits a message associated with the planar to the device, which is programmed to receive the message associated with the planar. If the message received by the device is not the message associated with the planar, the device is disabled.

A method and system for remotely storing a user's admin key to gain access to an intranet is presented. The user's admin key and intranet user identification (ID) are encrypted using an enterprise's public key, and together they are concatenated into a single backup admin file, which is stored in the user's client computer. If the user needs his admin file and is unable to access it in a backup client computer, he sends the encrypted backup admin file to a backup server and his unencrypted intranet user ID to an intranet authentication server. The backup server decrypts the user's single backup admin file to obtain the user's admin key and intranet user ID. If the unencrypted intranet user ID in the authentication server matches the decrypted intranet user ID in the backup server, then the backup server sends the backup client computer the decrypted admin key.

A method, system and computer program product for securing decrypted files in a shared environment. A filter driver in a kernel space may be configured to control service requests to encrypted files stored in a shared area, e.g., a shared directory on a disk unit, accessible by multiple users. The filter driver may receive a service request to open an encrypted document in the shared area issued from an authorized user. Upon receiving the encrypted data, the filter driver may decrypt the encrypted data. The filter driver may subsequently store the decrypted data in a file in a non-shared area, e.g., a non-shared directory. The non-shared area may be accessible only by the authorized user that requested access to the encrypted file. By storing the decrypted data in a file in the non-shared area, a file once decrypted may be protected in a file sharing environment.

An embedded security subsystem, and method for implementing the same, which provide secure controllability of a data security device within a data processing system. The embedded security subsystem of the present invention includes a persistent enable flag for providing control access to the data security device, wherein the persistent enable flag is accessible only in response to a power-on reset cycle of the data processing system. The persistent enable flag is read-only accessible to runtime program instructions. A pending state change flag that is write accessible by runtime program instructions is utilized for setting an intended next state of the persistent enable flag such that control access to the data security device is enabled only during a subsequent power-on reset of said data processing system.

A data processing system and method are disclosed for maintaining secure user private keys in a non-secure storage device. A master key pair is established for the system. The master key pair includes a master private key and a master public key. The master key pair is stored in a protected storage device. A unique user key pair is established for each user. The user key pair includes a user private key and a user public key. The user private key is encrypted utilizing the master public key. The encrypted user private key is stored in the non-secure storage device, wherein the encrypted user private key is secure while stored in the non-secure storage device.
