WebApr 15, 2024 · The spatial learned index constructs a spatial index by learning the spatial distribution, which performs a lower cost of storage and query than the spatial indices. The current update strategies of spatial learned indices can only solve limited updates at the cost of query performance. We propose a novel spatial learned index structure based on a … Webnon-linear operations in an AES-like block cipher execution by two (compared to the original AES Rijndael). We then describe a new block cipher for e cient masking, that combines these two ideas in order to reduce this total number of non-linear operations by a factor four. We call this cipher Zorro in reference to the masked ctional character.
