Abstract
The present disclosure provides a computer-implemented method for processing dynamic data by dynamic data processing device. The device comprises a homomorphic encryption module and a plurality of computing modules running in parallel. The method comprises carrying out, by the homomorphic encryption module, fully homomorphic encryption to dynamic data received from an object which generates the dynamic data; updating, by the computing module which is not in bootstrapping, the encrypted state variable; and carrying out, by the computing module which completes bootstrapping, the first update to the encrypted state variable. The first update to the encrypted state variable after completion of bootstrapping is carried out by(t+N)→A(t)+ΣAB((t+j)−(t+j)).
