Access to secure data through a portable computing system is provided only when a timer within the system is running. The timer is reset with the portable system connected to a base system, either directly, as by a cable, or indirectly, as through a telephone network. In an initialization process, the portable and base systems exchange data, such as public cryptographic keys, which are later used to confirm that the portable system is connected to the same base system. In one embodiment, the initialization process also includes storing a password transmitted from the portable system within the base system, with this password later being required within the reset process.

A Trusted Computing Platform Alliance (TCPA) endorsement certificate is provided by comparing a trusted platform module (TPM) public key transmitted by an owner of the computing device to which the TPM belongs to a copy of the key as originally stored in a remote database prior to vending the device. If a match is found the certificate is created using the public key, and then sent to the owner of the computing device.

A data processing system and method are described for providing a networked printer's physical location. The printer, a server computer system, and client computer systems are coupled together utilizing a network. The server computer system first transmits a command to the printer to disable the print function of the printer. Entry of a physical location of the printer is then permitted. The print function of the printer is reenabled by the server computer system only in response to an entry of the physical location of the printer into the printer.

A method for migrating a base chip key from a first computer system to a second computer system is disclosed. A first computer system includes a base chip key 1, and a second computer system includes a base chip key 2. Using a first certificate for the base chip key 1, a manufacturer of the second computer system generates a second certificate for the base chip key 1. Similarly, using a first certificate for the base chip key 2, a manufacturer of the first computer system generates a second certificate for the base chip key 2. A first data packet is then sent from the first computer system to the second computer system. The first data packet includes a first random number and all the data required to reproduce the base chip key 1 in the first computer system. The first data packet is also encrypted with the base chip key 1's public key. In return, a second data packet is sent from the second computer system to the first computer system, and the second data packet includes the first random number and a second random number, signed by the base chip key 2. The base chip key 1 is then erased from the first computer system. Finally, the base chip key 2 in the second computer system is replaced by the base chip key 1.

A method computer usable medium and computer system circuitry are disclosed for starting or “booting up” a computer from a remote location using a remote command device such as a cellular telephone. The method and system includes a secure means for remotely storing and transmitting security passwords.

A system and method for using a client-side hypervisor in conjunction with a secure network-side monitoring mechanism to detect removable media insertions since a client's last network session with the secure network is presented. The hypervisor uses a “client-side insertion value” to track the number of times that a user inserts removable media into a socket located on the client. When the client is connected to the secure network, the client's hypervisor notifies the secure network of each insertion and the secure network increments a “secure network-side tracker value.” For each login request, the client includes the client-side insertion value, which the secure network compares against its secure network-side tracker value. When the two values are different, the secure network sends an action request to the client, such as a request to perform a full system scan. Once the client performs the action, the client's hypervisor resets its client-side insertion value and attempts to logon to the secure network again.

A method, apparatus, and system are disclosed of forward caching for a managed client. A storage module stores a software image on a storage device of a backend server. The backend server provides virtual disk storage on the storage device through a first intermediate network point for a plurality of diskless data processing devices. Each diskless data processing device communicates directly with the first intermediate network point. The storage module caches an image instance of the software image at the first intermediate network point. A tracking module detects an update to the software image on the storage device. The storage module copies the updated software image to the first intermediate network point as an updated image instance.

An apparatus, system, and method are disclosed for granting hypervisor privileges. An installation module installs a monitor hypervisor wherein only the monitor hypervisor is granted the hypervisor privileges by the computer. An authentication module authenticates a second hypervisor. An eviction module evicts the monitor hypervisor if the second hypervisor is authenticated. The installation module further installs the second hypervisor after the monitor hypervisor is evicted so that only the second hypervisor is granted hypervisor privileges by the computer

A system, method, and program product is provided that initializes a counter maintained in a nonvolatile memory of a security module to an initialization value. The security module receives requests for a secret from requesters. The security module releases the secret to the requesters and the released secrets are stored in memory areas allocated to the requesters. A counter is incremented when the secret is released. Requestors send notifications to the security module indicating that the requestor has removed the secret from the requestor's memory area. The security module decrements the counter each time a notification is received. When the computer system is rebooted, if the counter is not at the initialization value, the system memory is scrubbed erasing any secrets that remain in memory.

A system, method, and program product is provided that establishes a shared secret between a computer system and a peripheral device such as a removable nonvolatile storage device or a printer. After establishing the shared secret, the peripheral device is locked. After the peripheral device is locked, an unlock request is received and the shared secret is sent to the peripheral device. The peripheral device then attempts to verify the shared secret. If the shared secret is successfully verified, then the peripheral device is unlocked allowing use of the device by using an encryption key that is made available by the verified shared secret. On the other hand, if the shared secret is not verified, then the peripheral device remains locked and use of the device is prevented.
