    Abstract: According to aspects of the present disclosure, there is provided methods and devices for verifying integrity of a remote device, including a method comprising generating a first nonce value, transmitting the first nonce value, receiving a message from the remote device, the message comprising measurements of a configuration of the remote device and a cryptographic signature based on a private key of a public-private key pair of the remote device and a second nonce value, determining that the second nonce value was generated based on the first nonce value, and verifying the cryptographic signature based on the second nonce value and a public key of the public-private key pair of the remote device.

    Abstract: In an example, a method includes obtaining an initial seed, a public parameter associated with a processing apparatus and an indication of a state of the processing apparatus. The method may further include generating, by the processing apparatus, a key corresponding to the state of the processing apparatus. The state of the processing apparatus may be based on a combination of the initial seed, the public parameter and the indication of the state.

    IPC: H04L9/32

    Abstract: In an example there is provided a method for a set of registered devices that are registered to participate in an authentication protocol, where each registered device has a share of an authentication key. The method comprises generating share data for a share of the authentication key. The share data is communicated from an authorised subset of the registered devices to a device. The share of the authentication key is generated at the device, on the basis of the share data. The share of the authentication key combines with shares of the registered devices to allow the device to participate in the authentication protocol.

    Abstract: A network printing system comprising a user device to encrypt a print job using a public key of a user and to transmit the encrypted print job to a print server. The system may further comprise the print server to re-encrypt the encrypted print job using the re-encryption key. The system may further comprise the printer to decrypt the re-encrypted print job using a private key of the printer and print the decrypted print job.

    CPC classification number: H04L9/0825 ,  H04L9/085

    Abstract: An apparatus, machine-readable instructions and a system to provision partial signing keys to approver devices are provided. A first plurality of partial signing keys is provisioned to a set of first approver devices. A request to execute a command is received and forwarded to multiple ones of the first approver devices. Responsive to the forwarded request, a threshold number of distinct partial signatures are received indicating approval for execution of the command, the approval being verifiable by combining of the threshold number of different partial signatures to generate a complete signature. The apparatus provisions a further partial signing key to a further approver device subsequent to execution of the approved command.
