In the Attribute-Based Encryption (ABE) scheme, patients encrypt their electronic health record (EHR), attach the appropriate attributes with it, and outsource them over the cloud. The underlying computational assumption is a problem that we call the computational reciprocal CSIDH problem, and that we prove polynomial-time equivalent to the computational CSIDH problem. The scheme consists of a constant number of isogeny computations. Our scheme uses the CSIDH framework and does not have an analogue in the Diffie-Hellman setting. We propose the first practical isogeny-based UC-secure oblivious transfer protocol in the presence of malicious adversaries. Hence it is not always possible to directly adapt existing protocols to the isogeny setting. Isogeny-based cryptography has some similarities to Diffie-Hellman, but lacks some algebraic properties that are needed for discrete-log-based OT protocols. One area of interest for post-quantum cryptography is isogeny-based crypto. An important goal is to have post-quantum OT protocols. The strongest security notion against malicious adversaries is universal composability (UC-secure).

Oblivious transfer (OT) is an essential cryptographic tool that can serve as a building block for almost all secure multiparty functionalities. Simulation results show that applying the SMC technique to preserve the privacy of organization policies causes only a little delay in SDNs, which is completely justifiable by the privacy obtained. We use Non-Dominated Sorting Genetic Algorithm II (NSGA-II) to determine the optimal number of controllers, and simulate SMC for typical SDNs with this number of controllers. To address this issue, we formulate an optimization problem to minimize the number of SDN controllers while considering their reliability in SMC operations. On the other hand, the number of controllers is one of the most important concerns in scalability of SMC application in SDNs. We borrow techniques from secure multi-party computation (SMC) to preserve the privacy of policies of SDN controllers about status of routers. Organizations often like to protect their internal network topology and keep their network policies private. In software-defined networking (SDN), controllers are sinks of information such as network topology collected from switches. Hence, our approach opens new opportunities for applying encrypted control. In addition, these approximations can be securely evaluated using garbled circuit in less than 100~ms for our numerical example. Fortunately, we illustrate that even low-dimensional learning-based approximations are sufficiently accurate for linear MPC. However, exact fits require high-dimensional preactivations of the neurons. These networks are of special interest for control since they allow, in principle, to exactly describe piecewise affine control laws resulting from, e.g., linear model predictive control (MPC). More precisely, we present a novel scheme that allows to efficiently implement (non-polynomial) max-out neural networks with one hidden layer in a secure fashion. We show in this paper that secure two-party computation using garbled circuits provides a powerful alternative to HE for encrypted control. Unfortunately, HE is computationally demanding and many control laws (in particular non-polynomial ones) cannot be efficiently implemented with this technology. Many existing approaches build on homomorphic encryption (HE) that allow simple mathematical operations to be carried out on encrypted data. Both of the solutions are highly efficient and significantly improve the previous work.Įncrypted control seeks confidential controller evaluation in cloud-based or networked systems. Specifically, based on this protocol, a cloud-assisted privacy-preserving profile-matching scheme and a secure remote health monitoring scheme are proposed. A part of this paper is devoted to applications of the proposed SSP protocol in secure cloud computing.

These bounds are not limited to SSP functionality but apply to a large class of two-party functionalities. To show the optimality of this SSP protocol, information theoretic lower bounds on the amount of communicated data in a secure two-party computation in the preprocessing model are derived.

In addition to full security, the proposed SSP protocol enjoys the advantage of optimal efficiency. Specifically, a perfectly secure and universally composable two-party split scalar product (SSP) protocol is proposed in the preprocessing model. This paper includes new results about the secure two-party scalar product. Secure computation of scalar product is of considerable importance due to its central role in many practical computation scenarios with privacy and security requirements.
