Abstract: An apparatus is disclosed. The apparatus may comprise a storage medium to store: a first data structure to receive a first plurality of numerical identifiers, each numerical identifier of the first plurality of numerical identifiers corresponding to a respective signal received during a first defined time interval; and a second data structure to receive a second plurality of numerical identifiers, each numerical identifier of the second plurality of numerical identifiers corresponding to a respective signal received during a second defined time interval, wherein the first defined time interval is earlier in time than the second defined time interval. The apparatus may comprise a processor. Upon expiry of a defined time period, the processor is to: delete the first data structure; and provide a third data structure to receive a third plurality of numerical identifiers, each numerical identifier of the third plurality of numerical identifiers corresponding to a respective signal received during a third defined time interval occurring after the second defined time interval. A method and a machine-readable medium are also disclosed.

Abstract: Examples disclosed herein relate to a content delivery network including a first and second mobile device. In one implementation, a peer to peer connection is established between a first and second mobile device to create a content delivery network. At least one of the mobile devices in the content delivery network may store content. In response to a request to render content, at least one of the mobile devices in the content delivery network may transmit the content to cause a content delivery device to render the content.

Abstract: In an example, a hypervisor measuring the state of a protected virtual machine using a Trusted Platform Module (TPM) filter. Using the TPM filter, the system ensures an untrusted operating system attempting to access the TPM is secure, without having to trust the security of the operating system or the operating system's built in hypervisor.

Abstract: A method for determining a connection status of a device to a cable within a network environment is provided. The method comprises obtaining a signal from a non-data carrying wire of the cable by a detector that is digitally isolated from data transmitted in a data carrying wire of the cable within the network environment, modifying the signal transmitted by the non-data carrying wire to the device and evaluating the modified signal to determine a connection status of the device to the cable.

Abstract: In an example, a method of encryption is described to include generation of a content encryption key and a key encryption key. In that example, the content encryption key is wrapped based on a key wrap operation using the key encryption key and the wrapped content encryption key is encrypted using a policy encryption key. Further in that example, the policy encryption key is encrypted using a public key corresponding to a print apparatus. In an example, a method of decryption is described. The example method of decryption performs recovery of a policy object using a private key corresponding to a print apparatus. In that example, the policy object includes a wrapped key that is unwrapped using a key encryption key to recover a content encryption key usable to decrypt an encrypted electronic document.

Abstract: A controller for a fulfilment service operation is described in which the controller, before initiating fulfilment of the job, operates to determine if an authorised user is present at a fulfilment service device and to determine if the user intends to remain attendant at the fulfilment service device for the duration of fulfilment of the job. If the user moves away from the fulfilment service device, the controller operates to pause the job. If the user remains away from the fulfilment service device for a period of time, the controller operates to cancel the job.

Abstract: Secure code image delivery may include encrypting, using an invariant content encryption key, an invariant portion of a code image for a set of electronic devices to generate an encrypted invariant potion of the code image. A first variant of a variant portion of the code image may be encrypted using a first variant content encryption key to generate a first encrypted variant portion. A second variant of a variant portion of the code image may be encrypted using a second variant content encryption key to generate a second encrypted variant portion. A code image bundle may be generated including the encrypted invariant portion, the first encrypted variant portion, and the second encrypted variant portion.
