Patent number: 11354399Abstract: A method for providing a set of certificates encoding authorisations, the method comprising processing respective ones of multiple authorisation requests at a trusted signing authority apparatus to verify respective digital signatures applied to the requests, the multiple authorisation requests received over a first communication link between the trusted signing authority apparatus and an administration apparatus, validating one or more authorisation request parameters of respective ones of the authorisation requests, generating a certificate encoding an authorisation at the trusted signing authority apparatus and transmitting the generated certificate to the administration apparatus or a requesting apparatus over a second communication link.Type: GrantFiled: July 17, 2017Date of Patent: June 7, 2022Assignee: Hewlett-Packard Development Company, L.P.Inventors: Joshua Serratelli Schiffman, Luke T. Mather, Christopher Charles Mohrman

Patent number: 11270012Abstract: In one example in accordance with the present disclosure, a computing device is described. The computing device includes an encryption device to encrypt, using an encryption key, a document to be rendered. A generating device generates multiple shares of a decryption key using a secret-sharing scheme. A threshold number of the multiple shares allows decryption of the document. A transmit device transmits different shares of the multiple shares to different devices. The document is rendered when the threshold number of multiple shares are rejoined at a rendering device.Type: GrantFiled: April 21, 2017Date of Patent: March 8, 2022Assignee: Hewlett-Packard Development Company, L.P.Inventors: Nassir Mohammad, Jonathan Griffin, Gurchetan Grewal, Luke T. Mather, Joshua Serratelli Schiffman

Patent number: 11146406Abstract: A method for managing entitlement of a device to access a service, the method comprising providing an authenticated identity for the device, the authenticated identity including a public encryption key pair associated with the device signed by a trusted authority, and generating a device entitlement certificate encoding an authorisation related to the service and including a public key of the public encryption key pair associated with the device, wherein the device entitlement certificate is signed by the trusted authority.Type: GrantFiled: July 26, 2017Date of Patent: October 12, 2021Assignee: Hewlett-Packard Development Company, L.P.Inventors: Joshua Serratelli Schiffman, Christopher Charles Mohrman, Luke T. Mather
