Abstract: A sign clip for a chain link fence includes a planar surface having a front surface and a back surface, the planar surface defining therethrough at least two holes of different diameters, wherein the planar surface loops back over the front surface on a first end and forms a first channel extending from the front surface, and wherein the planar surface loops perpendicular to the planar surface on a second end and forms a second channel extending perpendicular from the back surface.

Abstract: A publishing user publishes digital content and issues to itself a corresponding digital publisher license to allow itself to render the published digital content. The publishing user is supplied with a publishing certificate from a digital rights management (DRM) server, where the publishing certificate allows the publishing user to so publish the digital content and to so issue the publisher license.

Abstract: An access control policy engine associated with a resource determines whether to allow a request to access same. The engine receives the request with an security token, retrieves the token determines a type thereof, and maps access decision information in the token to a common format as at least one security claim setting forth adequate information to determine a right of the requestor. Thereafter, the engine retrieves a set of rules for accessing the resource, applies the rules to the security claims to determine whether to allow the request from the requestor, and if the request is to be allowed, provides the requestor access to the resource in accordance with the request and the rights of the requestor as determined based on the security claims.

Abstract: A resource of a first organization provides access thereto to a requestor of a second organization. A first administrator of the first organization issues a first credential to a second administrator of the second organization, including policy that the second administrator may issue a second credential to the requestor on behalf of the first administrator. The second administrator issues the second credential to the requester, including the issued first credential. The requestor requests access from the resource and includes the issued first and second credentials. The resource validates that the issued first credential ties the first administrator to the second administrator, and that the issued second credential ties the second administrator to the requester. The resource thus knows that the request is based on rights delegated from the first administrator to the requester by way of the second administrator.

Abstract: A digital certificate is employed to produce a digital signature for a digital construct. In the digital certificate is set forth a certificate validity period defining for the digital certificate a time period during which the digital certificate is to be honored as valid for producing digital signatures, and a signature validity period defining for each digital signature produced based on the digital certificate a time period during which the digital signature is to be honored as valid.

Abstract: A digital certificate identifies an entity as having authority over the certificate to revoke same as delegated by the issuer. The certificate also has at least one revocation condition relating to possible revocation of the certificate. To authenticate the certificate, the identification of the delegated revocation authority, a location from which a revocation list is to be obtained, and any freshness requirement to be applied to the revocation list are determined from the certificate. It is then ensured that the revocation list from the location is present and that the present revocation list satisfies the freshness requirement, that the revocation list is promulgated by the delegated revocation authority identified in the certificate, and that the certificate is not identified in the revocation list as being revoked.

Abstract: A trusted data store is provided for use with a trusted element of a trusted operating system on a computing machine. In the trusted data store, a storage medium stores data in a pre-determined arrangement, where the data includes trusted data from the trusted element of the trusted operating system on the computing machine. An access controller writes data to and reads data from the storage medium, and a trust controller is interposed between the computing machine and the access controller. The trust controller allows only the trusted element to perform operations on the trusted data thereof on the storage medium.
