| Abstract(in English) | Networked control systems are constantly exposed to the threat of cyberattacks by malicious third parties. Cyberattacks against a control system that are difficult to deal with only by protecting data over communication links have been reported, such as falsifying and spoofing data inside a control device by unauthorized access. This talk introduces an encrypted control that aims to protect the data over the communication links and inside a controller in the control system. The encrypted control is realized by reconfiguring (encrypting) the controller using homomorphic encryption, which can lead to a discussion of the security of the encrypted control system from the viewpoint of cryptographic theory. Considering a cyberattack scenario in which the encrypted controller (parameters of functions) is estimated from the input and output signals in a ciphertext, this talk discusses the relationship between the security under the cyberattack scenario and the IND-CPA (Indistinguishability under Chosen Plaintext Attack) security. Finally, it provides the importance and prospects of incorporating theoretically provable security concepts into control problems to generalize the control system security. |
