Secure and Private Implementation of Dynamic Controllers Using Semi-Homomorphic Encryption (1812.04168v2)
Published 11 Dec 2018 in math.OC, cs.CR, and cs.SY
Abstract: This paper presents a secure and private implementation of linear time-invariant dynamic controllers using Paillier's encryption, a semi-homomorphic encryption method. To avoid overflow or underflow within the encryption domain, the state of the controller is reset periodically. A control design approach is presented to ensure stability and optimize performance of the closed-loop system with encrypted controller.
