Abstract
A computer-implemented method is provided for processing dynamic data in the environment comprising a device to be controlled, a controller generating a control command (u(t)), a decryption module which decrypting an encrypted control command received from the controller, an actuator which operates according to the decrypted control command received from the decryption module, a sensor which detects the output (y(t)) of the device and a homomorphic encryption module which homomorphically encrypts the signal of the sensor. The method of the present disclosure comprises transforming, by the controller, the state-space representation of the controller 'x(t+1)=Fx(t)+Gy(t), u(t)=Hx(t)+Jy(t)' into 1/s is larger than 1; r is larger than zero; wis a variable of the state-space representation of the controller after Kalman observable decomposition is carried out to the original state-space representation of the controller); and calculating, by the controller, Rand Twhich makes T(F−RH)Tan integer matrix.
