Patent number: 8549592Abstract: A method and apparatus are disclosed in a data processing system for establishing virtual endorsement credentials. The data processing system includes a hardware trusted platform module (TPM). Logical partitions are generated in the system. A different virtual TPM is generated for each one of the logical partitions. For each one of the logical partitions, the virtual TPM that was generated for the logical partition then dynamically generates a virtual endorsement key, which is stored only within a corresponding virtual TPM. Using the virtual endorsement key, each virtual TPM also generates a virtual endorsement credential for use by the logical partition that includes the virtual TPM. The virtual endorsement credential is generated within the data processing system without the data processing system or its devices accessing a trusted third party that is external to the data processing system.Type: GrantFiled: July 12, 2005Date of Patent: October 1, 2013Assignee: International Business Machines CorporationInventors: Steven A.

Patent number: 8495361Abstract: A method and system for ensuring security-compliant creation and signing of endorsement keys of manufactured TPMs. The endorsement keys are generated for the TPM. The TPM vendor selects an N-byte secret and stores the N-byte secret in the TPM along with the endorsement keys. The secret number cannot be read outside of the TPM. The secret number is also provided to the OEM's credential server. During the endorsement key (EK) credential process, the TPM generates an endorsement key, which comprises both the public key and a hash of the secret and the public key. The credential server matches the hash within the endorsement key with a second hash of the received public key (from the endorsement key) and the vendor provided secret. The EK certificate is generated and inserted into the TPM only when a match is confirmed.Type: GrantFiled: September 21, 2007Date of Patent: July 23, 2013Assignee: International Business Machines CorporationInventors: Ryan Charles Catherman, David Carroll Challener, James Patrick Hoff

Patent number: 8086852Abstract: A method is presented for implementing a trusted computing environment within a data processing system. A hypervisor is initialized within the data processing system, and the hypervisor supervises a plurality of logical, partitionable, runtime environments within the data processing system. The hypervisor reserves a logical partition for a hypervisor-based trusted platform module (TPM) and presents the hypervisor-based trusted platform module to other logical partitions as a virtual device via a device interface. Each time that the hypervisor creates a logical partition within the data processing system, the hypervisor also instantiates a logical TPM within the reserved partition such that the logical TPM is anchored to the hypervisor-based TPM. The hypervisor manages multiple logical TPM's within the reserved partition such that each logical TPM is uniquely associated with a logical partition.Type: GrantFiled: September 9, 2008Date of Patent: December 27, 2011Assignee: International Business Machines CorporationInventors: Steven A.

Patent number: 7752458Abstract: An architecture for a distributed data processing system comprises a system-level service processor along with one or more node-level service processors; each are uniquely associated with a node, and each is extended to comprise any components that are necessary for operating the nodes as trusted platforms, such as a TPM and a CRTM in accordance with the security model of the Trusted Computing Group. These node-level service processors then inter-operate with the system-level service processor, which also contains any components that are necessary for operating the system as a whole as a trusted platform. A TPM within the system-level service processor aggregates integrity metrics that are gathered by the node-level service processors, thereafter reporting integrity metrics as requested, e.g., to a hypervisor, thereby allowing a large distributed data processing system to be validated as a trusted computing environment while allowing its highly parallelized initialization process to proceed.Type: GrantFiled: October 24, 2008Date of Patent: July 6, 2010Assignee: International Business Machines CorporationInventors: Steven A.

Patent number: 7743406Abstract: A system and method for securing data on a wireless device. A secured zone is defined by a boundary sensor. A data processing system is coupled to the boundary sensor and a wireless device. If the data processing system detects that the signal strength of the wireless device has fallen below a first predetermined value for longer than a second predetermined value, the data processing system deletes a digital certificate corresponding to the wireless device from memory. Thus, when the wireless device is reintroduced into the secured zone, in response to determining that a digital certificate corresponding to the wireless device is not stored in memory, the disabling module disables the wireless device from operation within the secured zone.Type: GrantFiled: December 21, 2004Date of Patent: June 22, 2010Assignee: International Business Machines CorporationInventors: Scott Sina Abedi, Roger Kenneth Abrams, Ryan Charles Catherman, James Patrick Hoff, James Stephen Rutledge

Patent number: 7673134Abstract: 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.Type: GrantFiled: April 7, 2005Date of Patent: March 2, 2010Assignee: Lenovo (Singapore) Pte.
