  • Patent number: 11159513
    Abstract: Embodiments facilitate the management of security certificates for printers that are used in public locales. The system communicates with and manages the printers with the benefits of security certificate protocols on-demand as a user requests to print documents with any particular printer. Once a document is requested to be printed at a printer, the system registers the printer with the network. At registration, a gateway is automatically installed. the gateway requests a security certificate which is stored on the printer or its associated computer. Aspects thus solve an online service's need to install and manage certificates for any printer accessible to the network.

  • Patent number: 11153344
    Abstract: To establish a first protected communication channel between a device D and a first server S, a symmetric key KS is derived at the device D, based on a device identifying key KD and public key information dependent on a first server public key Spublic of the first server S. The symmetric key KS is derived in a corresponding way at a second server T. The symmetric key KS is transmitted from the second server T to the first server S on a second protected communication channel. Communication on the first protected communication channel between the device D and the first server S is protected using a communication key KC which is dependent on the symmetric key KS. This can enable a device D lacking support for asymmetric key cryptography to securely enter into communication with the first server S.
