A trusted platform module is presented that is capable of creating, dynamically, multiple virtual trusted platform modules in a hierarchical organization. A trusted platform module domain is created. The trusted platform module creates virtual trusted platform modules, as needed, in the trusted platform module domain. The virtual trusted platform modules can inherit the permissions of a parent trusted platform module to have the ability to create virtual trusted platform modules themselves. Each virtual trusted platform module is associated with a specific partition. Each partition is associated with an individual operating system. The hierarchy of created operating systems and their privilege of spawning new operating systems is reflected in the hierarchy of trusted platform modules and the privileges each of the trusted platform modules has.

Dynamic creation and hierarchical organization of trusted platform modules

Deploying an encrypted entity on a trusted entity is illustrated herein A method includes, at a trusted entity, wherein the trusted entity is trusted by an authority as a result of providing a verifiable indication of certain characteristics of the trusted entity meeting certain requirements, receiving an encrypted entity from an untrusted entity The untrusted entity is not trusted by the authority At the trusted entity, a trust credential from the authority is used to obtain a key from a key distribution service The key distribution service is trusted by the authority The key is used to decrypt the encrypted entity to allow the encrypted entity to be deployed at the trusted entity

Secure Management of Operations on Protected Virtual Machines

A method and apparatus for trusted authentication and logon is disclosed. A trusted platform module (TPM) based logon method is presented for authentication and access. A user registers an identity with an identity provider that is tightly bound to the user's specific platform, e.g., the TPM. If the user decides to login, for example to a service provider using this identity, the identity provider challenges the user to provide the correct credentials. The credentials consist of a TPM generated ticket, that is, a credential chain. This allows the user to login without the need for a password at the identity provider.

Method and apparatus for trusted authentication and logon

Methods and apparatus are disclosed to perform a secure boot of a computer system An example method disclosed herein receives an initialization routine having at least one sub-routine, measures the initialization routine to compute a hash value, and compares the computed hash value with a core root of trust hash value to verify the initialization routine The example method disclosed herein also establishes trust to the initialization routine when the computed hash value matches the core root of trust hash value and hands-off platform hardware to an operating system in response to successful verification of the initialization routine Other embodiments are described and claimed

Methods and apparatus to perform secure boot

A network device connected via a bus with a plurality of network devices includes: an authentication unit that executes authentication based upon message authentication information included in data transmitted, via the bus, by one of the plurality of network devices acting as a sender device; and a processing unit that invalidates the data upon determining that unauthorized data have been transmitted by the sender device impersonating another network device among the plurality of network devices if the authentication fails.

A method, apparatus, and computer program product 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 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.

Method, apparatus, and product for establishing virtual endorsement credentials for dynamically generated endorsement keys in a trusted computing platform

PROBLEM TO BE SOLVED: To provide a method, apparatus and computer program for establishing virtual endorsement credentials in a data processing system. SOLUTION: 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 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.

Method, apparatus and computer program for establishing virtual endorsement credential for dynamically generated endorsement key in trusted computing platform

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.
