Abstract: Disclosed embodiments implement rekeying keys of a Security Association (SA) using an SPI Transform to provide secure data transfer in a computing environment. A disclosed method comprises detecting, by a local key manager (LKM) executing on a computing node, an expired rekey timer of an SA between an initiator channel on the computing node and a responder channel on a responder node. The LKM requests, based on the expired rekey timer, an SA Index from the initiator channel on a computing node. The LKM creates an SPI based on an SPI Transform using the new SA Index and SPI Transform values. The LKM builds an SKE SA Initialization Request message based on an authentication key of the SA and the SPI to obtain a new session key.

Abstract: A label modification unit may receive a label modification input that indicates a label modification associated with content being written to a label or erased from the label. The label modification unit may identify an area of the label that is associated with the label modification according to the label modification input. The label modification unit may determine, based on a size of the area, a spot size of a light beam that is configured to be emitted by a laser printhead to modify the content within the area. The label modification unit may determine, based on the spot size and the content, an optical path configuration for the laser printhead. The label modification unit may operate the laser printhead according to the optical path configuration to write the content to the area or erase the content from the area.

Abstract: A utility consumption information system may generate a variety of data that is based on and/or derived from utility consumption or usage associated with a site. In some examples, the utility consumption information system may generate data to be provided or displayed by applying a load profile to utility consumption or usage data obtained at the site over a period of time. The utility consumption information system may generate the load profile based on sample interval data obtained from one or more devices (e.g., utility metering devices) sharing characteristics with the site at which the utility consumption or usage data was obtained.
