Patent number: 11979506Abstract: 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.Type: GrantFiled: July 14, 2020Date of Patent: May 7, 2024Assignee: SOUTHWEST PETROLEUM UNIVERSITYInventors: Xiaojun Zhang, Chao Huang, Jingwei Zhang, Jie Gong, Ziyu Zhou, Shuang Zheng, Jie Zhao

Publication number: 20240070135Abstract: Systems and methods are provided for improved point querying of a database. The index values are separated from data and retained in cache memory to allow access without requiring a disk input/output (I/O) operation and thereby having less latency resulting from such disk I/O operations. The index values can be compressed using an algorithm such as Crit-Bit-Trie to allow storage of the index values in limited cache memory space. The index values can be selected for storage according to a least recently used approach when cache memory is insufficient to store all index values to maintain a hit rate for the cached portion and reduce the disk I/O operations.Type: ApplicationFiled: September 27, 2023Publication date: February 29, 2024Inventors: Jiaxin Ou, Jingwei Zhang, Hao Wang, Hui Zhang, Ming Zhao, Yi Wang, Zhengyu Yang
