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.

Abstract: Methods, systems, and devices for determining offsets for memory read operations are described. In response to a threshold quantity of pages failing initial reads but being successfully read using a same reference adjustment during re-reads, the offset responsible for the adjustment may be used as a first-applied offset for subsequent re-reads or a baseline offset for subsequent initial reads. After the initial reads begin using the reference adjustment, if a threshold quantity of pages fail initial reads, the offset used for the initial read may be adjusted to be the offset used to perform the successful re-reads. If an updated offset to use a baseline is not identified, the baseline offset may be cleared so the original reference may again be used without adjustment for initial reads.
