Abstract:
Recent booming growth of cloud computing and Big Data &AI have brought numerous challenges to resource scheduling and security fromboth insider and outsider threats. The encrypted data are relatively considered a safe storage status. However,the process of encrypting data is still facing adversarial actions and data process generally is inapplicable over cipher-texts.As a type of the encryption approach allowing computations over cipher-texts, a Fully Homomorphic Encryption (FHE) canconcurrently deal with the adversarial hazards and support computations on cipher-texts. This research focuses on the issue ofblend arithmetic operations over real numbers and proposes a novel tensor-based FHE solution with limited resources available. The proposed approach is calleda Fully Homomorphic Encryption for Blend Operations (FHE-BO) model that uses tensor laws to carry the computations of blendarithmetic operations over real numbers. The experimental results have depicted that our approach is superior in security protection and resource usage to previous methods.
