A data processing system accepts a removable storage media, which becomes electrically engaged with a system unit within the data processing system, after which the removable storage media and the hardware security unit mutually authenticate themselves. The removable storage media stores a private key of a first asymmetric cryptographic key pair and a public key of a second asymmetric cryptographic key pair that is associated with the hardware security unit, and the hardware security unit stores a private key of the second asymmetric cryptographic key pair and a public key of the first asymmetric cryptographic key pair that is associated with the removable storage media. In response to successfully performing the mutual authentication operation between the removable storage media and the hardware security unit, the system unit is enabled to invoke cryptographic functions on the hardware security unit while the removable storage media remains engaged with the system unit.

A method and system for verifying binding of an initial trusted device to a secured processing system binds an initial device or replacement when no binding information is available from another device in the system. A platform credential is issued only when a valid binding is verified, by sending a proof of binding to a credential provider, such as the manufacturer. The method secures against security breaches that can occur when a device is removed from the system during the binding process. The binding information is generated in the device upon installation and includes system identification information so that at each initialization, upon return of binding information from the system to the device, the device can ensure that it is installed in the proper system and abort operation if the system does not match.

A data processing system, method, and product are disclosed for pre-encrypting static information transmitted by secure Web sites. The data processing system includes a server computer system coupled to a client computer system utilizing a network. The server computer system receives a request for a secure Web page that is maintained by the server. The secure Web page includes dynamically-changing information and static information. The server encrypts and transmits the encrypted dynamically-changing information. The server determines whether the static information has been pre-encrypted. If the static information has been pre-encrypted, the server bypasses the encryption step and transmits the pre-encrypted static information.

The present invention is embodied in a system and method for providing positional authentication for client-server systems, such as extranets. In general, an authentication system of the present invention controls and authenticates access rights to a host server from a client machine that desires access to the host server via a network connection, such as an extranet connection. Specifically, the present invention includes a client machine coupled to a host server, via any suitable connection, such as an extranet, and a wireless positioning system, such as a global positioning satellite (GPS). The client machine can be any suitable client computer machine, such as a desktop computer, portable notebook computer or the like. The client machine includes a positioning receiver and a positional relation module. The host server includes an authentication module with predefined access parameters for standard and positional authentication. A portion of the predefined access parameters is used to associate specific locations of the client machine with access rights for positional authentication.

A method to enable access to resources hosted in a compute cloud begins upon receiving a registration request to initiate a user's registration to use resources hosted in the compute cloud. During a registration process initiated by receipt of the registration request, a federated single sign-on (F-SSO) request is received. The F-SSO request includes an assertion (e.g., an HTTP-based SAML assertion) having authentication data (e.g., an SSH public key, a CIFS username, etc.) for use to enable direct user access to a resource hosted in the compute cloud. Upon validation of the assertion, the authentication data is deployed within the cloud to enable direct user access to the compute cloud resource using the authentication data. In this manner, the cloud provider provides authentication, single sign-on and lifecycle management for the user, despite the “air gap” between the HTTP protocol used for F-SSO and the non-HTTP protocol used for the user's direct access to the cloud resource.

A technique for addressing geographical location issues in a computing environment includes receiving, at a data processing system, location information indicating a permissible geographical location in which a virtual machine image for a consumer may be deployed. A request for an exception to deploy the virtual machine image outside of the permissible geographical location is issued, from the data processing system. An exception grant or an exception denial is received, at the data processing system, from the consumer in response to the request. The virtual machine image is deployed, using the data processing system, to one or more servers in the computing environment that are outside of the permissible geographical location in response to receipt of the exception grant. The virtual machine image is deployed, using the data processing system, to one or more servers in the computing environment that are within the permissible geographical location in response to receipt of the exception denial.

Despite the best intentions of a cloud service provider, digital assets of may be moved to a geographic location that deviates from a geographic preference, policy, or setting of the owner of the digital assets. A monitoring tool can monitor network location of a digital asset hosted by a cloud service provider. Movement of the digital asset from a first network location to a second network location is detected. In response to detecting that the digital asset moves, a geographic location that corresponds to the second network location is determined. It is then determined that the geographic location deviates from a geographic setting configured for the digital asset. A notification that the digital asset has been moved to the geographic location that deviates from the geographic setting is generated.

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.
摘要:
A method, system, and computer usable program product for securing asynchronous client server transactions are provided in the illustrative embodiments. A request including an application identifier and a version of a second application is received at a first application. A service identifier is generated if a session with the second application is valid. A registry is generated at the first application. A catalog is generated based on the registry and the service identifier and the catalog are sent to the second application. A sub-request including the service identifier is received as part of an asynchronous client server transaction. Validity of the sub-request is determined by determining whether the service identifier has expired, whether the sub-request requests a service that is permissible according to the catalog, whether the service identifier is used in conjunction with the second application, or a combination thereof. If the sub-request is valid, the service is provided.
摘要:
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.
