(MPC) protocol called SPDZ (Damgård et al., Crypto ’12). MP-SPDZ extends SPDZ-2 to 34 MPC protocol variants, all of which can be used with the same high-level programming interface based on Python. This considerably simplifies comparing the cost of different protocols and security models. The protocols cover all commonly used security models (hon-est/dishonest majority and semi-honest/malicious …

Sharemind MPC supports several different MPC schemes called protection domains, with the shared3p protection domain being the most advanced one. Sharemind is a novel database and application server that collects data in an encrypted form and uses techniques like homomorphic encryption, secure multi-party computation and hardware isolation to process it without leaking the private inputs even to the machine memory, providing end-to-end encrypted data processing. MPC 3.1 The Sharemind MPC framework Sharemind is a programmable distributed secure computation framework [4] supporting MPC. Sharemind is designed to be a database and application server that provides cryptographic protection for data during both storage and processing.

As outlined in Figure 2, we rely on a platform for MPC (in our case Sharemind ) that takes the event logs of the participating parties, i.e., L a and L b, as secret-shared input. Inside the MPC platform, the respective data is processed in a privacy-preserving way in order to answer analysis queries over the time-annotated DFG computed from

Sharemind MPC is a practical implementation of secure multi-party computation technology with the emphasis on performance and ease of use. Sharemind MPC supports several different SMC schemes called protection domains, but the SUNFISH platform uses the shared3p protection domain, which stands for 3-out-of-3 secret sharing with passive security. Sharemind uses MPC to analyse data that was not accessible before.

Sugar Beet Auction The classic example of a problem where MPC can be MPC have been known for decades [1]–[3], and the past and framework choice to pick between diﬀerent MPC backends (e.g., VIFF, Sharemind) to use in a particular Sharemind is a database with a built-in non-disclosure agreement. Secure multiparty computation technology allows Sharemind to process secret-shared/encrypted data. all worker nodes (e.g., the result of an MPC task). 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].
