    摘要: A method to verify a geographic location of a virtual disk image executing at a data center server within a data center. One embodiment includes a cryptoprocessor proximate the data center server, a hypervisor configured to send a disk image hash value of the virtual disk image, a digital certificate issued to the cryptoprocessor, an endorsement key to a data center tenant and a location provider. The method includes sending a disk image hash value of the virtual disk image, an endorsement key unique to a cryptoprocessor proximate the data center server to a data center tenant, and a digital certificate to a data center tenant. Next, the location provider sends the geographic location of the cryptoprocessor matching the endorsement key to the data center tenant.

    摘要: A public key infrastructure comprising a participant that issues digital certificates. Each digital certificate can be relied upon in at least two different trust domains. The public key infrastructure does not employ policy mapping between or among the trust domains. Furthermore, the public key infrastructure does not link any pair of trust domains via cross-certificates. Just one trust domain is bound to the digital certificate at any given moment. The current trust domain that is to be bound to the digital certificate is elected by a relying party at the time of reliance, based upon a specific certificate validation methodology selected by the relying party.

    摘要: A system, apparatus, method, and machine readable medium are described for performing transaction signing within an authentication framework. For example, one embodiment of a method comprises: executing an online transaction between a first server and a client; providing transaction details of the online transaction to a second server; generating a signature over the transaction details using a key at the second server; transmitting an authentication request to the client with the signature and the transaction details; authenticating a user on the client to generate authentication data, the authentication data specifying whether the user was successfully authenticated on the client; and transmitting the authentication data, the transaction details, and the signature to the second server; using the transaction details and the key to validate the signature and using the authentication details to authenticate the client at the second server, wherein upon validating the signature and authenticating the client, the second server transmits a confirmation for the transaction to the first server.

    摘要: A signature generation and verification system including a signature generation apparatus and a signature verification apparatus is provided. Based on signer certification information possessed by a signer, the signature generation apparatus generates a digital signature and verification data corresponding to a given electronic document and outputs the set of the digital signature and the verification data as signature data. Upon receipt of the electronic document and the signature data, the signature verification apparatus verifies the digital signature using the verification data to verify the integrity of the electronic document. As needed, the signature verification apparatus performs user identification ex-post facto by authenticating that the signer certification information from which the verification data was generated belongs to a legitimate user without knowledge of the signer certification information.

    摘要: A receiver comprises a security processor and a first memory that stores software code or second stage authentication key and a signature for the software or the second stage key. The receiver also stores a plurality of verification keys (PUAK). When the receiver is switched on or reset, the software or second stage key and the signature are loaded from the first memory. The security processor then loads a PUAK and uses it to verify the signature. In case of successful verification, the software code or second stage key is used and the verification method ends; it is then possible to activate CA specific functions in the receiver. However, if the verification is unsuccessful, then it is verified if there are untried PUAKs. If there are no untried signatures, then the verification has failed and the software cannot be verified; the verification method ends. If there are untried signatures, then the next PUAK is loaded.
