Abstract: Techniques for low latency updating of an electrophoretic panel are described. According to such techniques, pixels may be continuously scanned out instead of buffering and updating at fixed scanning slots. In an example, a controller of a device loads, before receiving update data associated with a pixel of an electrophoretic panel, a LUT into a memory accessible to a LUT hardware module. After the LUT is loaded into the memory, the controller receives the update data indicating a color change to the pixel and associates the update data with the LUT. Based at least in part on the update data and the LUT, the controller determines waveform data corresponding to the color change and causes an output on the electrophoretic panel based at least in part on the waveform data.

Abstract: In a method for statistical analysis of aggregate encrypted data with key-leakage resilience for smart grids, every user area is managed by a fog node which plays the role of data aggregation gateway and data relay. All the users' electricity consumption data sent by smart meters in the same user area are firstly aggregated by the fog node to generate a fog-level aggregate ciphertext. Then the fog node further generates a digital signature for the fog-level aggregate ciphertext and sends these data to a cloud server for long-time storage. The cloud server stores all the aggregate ciphertexts and digital signatures received from different user areas in its database, and provides data query and statistical analysis services for the control center of smart grids. On the premise of without violating users' privacy, the cloud server could provide enough information for the control center, enabling it to compute the sum, arithmetic mean and variance of all users' data in specified areas in a privacy-preserving way.
