Multi-party computation enables secure polynomial control based solely on secret-sharing. (arXiv:2103.16335v2 [eess.SY] UPDATED)

Encrypted control systems allow to evaluate feedback laws on external servers
without revealing private information about state and input data, the control
law, or the plant. While there are a number of encrypted control schemes
available for linear feedback laws, only few results exist for the evaluation
of more general control laws. Recently, an approach to encrypted polynomial
control was presented, relying on two-party secret sharing and an inter-server
communication protocol using homomorphic encryption. As homomorphic encryptions
are much more …
