I/O Performance Improvement of FHE Apriori with Striping File Layout Considering Storage of Intermediate Data

Fully homomorphic encryption (FHE) enables secret computations. Users can perform computation using data encrypted with FHE without decryption. Uploading private to a public cloud has the risk of leakage, which makes many users hesitant utilize cloud. avoids this risk, while still providing computing power In cases, are stored in HDDs because size increases significantly when is used. One important analysis Apriori mining. application, two files accessed alternately, and causes long-distance seeking on its HDD low performance. paper, we propose new striping layout reservations for write areas. This method intentionally fragments arranges blocks reduce distance between file another file. It reserves area intermediate Apriori. The performance proposed was evaluated based I/O processing large Apriori, results showed that could improve by up approximately 28%.
