Sharemind MPC (Multi-Party Computation) End-to-end data protection with accountability In a service powered by Sharemind, data owners encrypt their data on premises and upload them to Sharemind. The host of a Sharemind server cannot decrypt the values or learn anything from them.

Previously also programmer (2011), researcher (until 2016) and security engineer (until Sharemind SQL is a relational database management system which uses Sharemind MPC to store and process the data. Sharemind SQL provides secure database querying and data processing. That allows sensitive data to be aggregated for providing insights while protecting confidentiality on individual record and field level. The Sharemind system uses three servers to hold the shares of secret val-ues. In Sharemind terminology, these servers are data miners.

Therefore, the 13 Jan 2020 They evaluated 9 frameworks: EMP-toolkit, Obliv-C, ObliVM, TinyGarble, SCALE- MAMBA, Wysteria, Sharemind, PICCO, and ABY. Overall, the Fast and easy-to-use Secure MPC on Big Data. open-source on Github, and it currently supports MPC computation using the Sharemind and Obliv-C systems.

This means that as long as the parties are following the protocols honestly and do not collude, none of them will learn more than the size of the data. Parties in a typical secure MPC deployment Product Owner, Sharemind MPC Cybernetica Jan 2011 - Present 10 years 2 months.

MPC frameworks such as VIFF [1], Sharemind [3], and Wyste ria [10] allow end- users to run arbitrary programs in MPC, as long. Permission to make digital or

Since each MPC task requires the participation of all worker nodes, diverging control ﬂow could lead to a deadlock of the system if diﬀerent worker nodes attempt to execute diﬀerentMPCtasks. Before evaluating the next local MapReduce or MPC task, each worker node registers with the Another MPC approach is based on the garbled circuits method (GC) attributed to Yao [35] and detailed in [26].

Introduction. Following the success of deploying secure multi-party computation for a secure double auction in Denmark in 2008 and for the financial reporting of the ICT sector in Estonia in 2011, Cybernetica has developed a new MPC application together with a web-based frontend that provides statistical analysis of incomes in public sector Only very limited commercial applications of MPC exists, e.g, by Sharemind. MPC has received increasing interest in recent years. Some of the most sophisticated protocols so far are SPDZ and its successors based on secret sharing. It is implemented e.g., in the SCALE-MAMBA software package.

MPC is used to remove the need for a trusted third party that performs the computation. Recently MPC has developed from a purely theoretical research ﬁeld into a multitude of practical deployments. An overview of numerous MPC applications is given by Archer et al. [Arc+18].

Sharemind MPC frameworks, which limit MPC steps to two or three parties, but adding support for further frameworks requires only modest effort. 2 Motivation and background MPC jointly executes an agreed-upon computation across several parties’ private data without a trusted party. MPC has served purposes from detecting VAT tax fraud by analyzing
