报告题目：Closing The Loop Over Encrypted Signals
报告摘要：In this talk, networked control systems with encrypted sensors measurements is considered. Semi-homomorphic encryption is used so that the controller can perform the required computation on the encrypted data. Specifically, in this work, the Paillier encryption technique is utilized that allows summation of decrypted data to be performed by multiplication of the encrypted data. Conditions on the parameters of the encryption technique are provided that guarantee the stability of the closed-loop system and ensure certain bounds on the closed-loop performance. Furthermore, the extension of the methodology to distributed systems will be introduced. Some experiment result will conclude this talk.
