Andreea B. Alexandru, Anastasios Tsiamis, George J. Pappas

摘要:

我们提供了一个有效的和私人的解决方案,以解决问题的防御感知数据驱动的控制。我们调查了一个控制即服务的场景,其中客户端采用服务提供商提供的专业外包控制解决方案。客户端系统的隐私敏感模型参数不可用或可变。因此,我们要求服务提供者以隐私保护的方式对来自客户端的输入-输出数据样本执行数据驱动控制。为此,我们共同设计的控制方案方面的控制性能和隐私规范。首先,我们制定我们的控制算法的基础上,最近的结果从行为框架,我们证明了经典的配方和我们的配方,占噪声和加密所产生的精度误差之间的接近。其次,我们使用了一个国家的最先进的水平同态加密计划,使服务提供商执行高复杂度的计算客户端的加密数据,确保隐私。最后,我们简化我们的解决方案,利用丰富的数据结构,并精心采用密文加密和重排操作,使并行化。与我们以前的工作相比,该解决方案实现了两倍以上的运行时间和内存改进。

英文摘要:

We provide an efficient and private solution to the problem of encryption-aware data-driven control. We investigate a Control as a Service scenario, where a client employs a specialized outsourced control solution from a service provider. The privacy-sensitive model parameters of the client's system are either not available or variable. Hence, we require the service provider to perform data-driven control in a privacy-preserving manner on the input-output data samples from the client. To this end, we co-design the control scheme with respect to both control performance and privacy specifications. First, we formulate our control algorithm based on recent results from the behavioral framework, and we prove closeness between the classical formulation and our formulation that accounts for noise and precision errors arising from encryption. Second, we use a state-of-the-art leveled homomorphic encryption scheme to enable the service provider to perform high complexity computations on the client's encrypted data, ensuring privacy. Finally, we streamline our solution by exploiting the rich structure of data, and meticulously employing ciphertext batching and rearranging operations to enable parallelization. This solution achieves more than twofold runtime and memory improvements compared to our prior work.
