The next generation of privacy-preserving software solutions

MPC and Cloud

Partisias’s basic cryptographic infrastructure tacles fundamental security problems with cloud computing.
By use of advanced cryptography with no single point of trust, the basic problem of whom to trust while tapping into the benefits of the cloud is greatly simplified.

Partisia develop secure statistical solutions for a broad class of applications.
By advance cryptography the statistical solutions keep the raw data encrypted at all time, and only the intended results are revealed.

This highly controlled use of data makes it safer and simpler to provide data.

Secure order matching

In collaboration with Tora, Partisia has developed SMC infrastructure for the next generation of financial order matching. Tora is the provider of the industry’s most advanced cloud-based order and execution platform (OEMS) and operator of Crosspoint also known as off-exchange matching. Every day over three billion dollars of institutional volume is traded through the Tora platform.

The MPC infrastructure is a unique protocol called MACE (Multiparty Agile Computation Engine) that meets the very high security, performance and flexibility requirements needed. Tora apply MACE in the Crosspoint matching service to avoid any data leakages or misuse of information on financial exchanges.
The Tora case is one of the most advanced uses of MPC.

Partisia Infrastructure

Partisia offers a generic platform (The PBC Platform) that makes it simple to apply MPC and build provably secure MPC applications. The PBC platform was released in version 1.0 in August 2019 and the first applications within market design and statistics are being developed in close collaboration with the initial customers. The platform provides a unique balance between transparency and confidentiality and remove the barriers and reduce costs involved in adapting MPC.

The platform enables the next generation of privacy-preserving application for a data-driven economy.

Public-private data collaboration

SECATA develops a generic infrastructure for a privacy-preserving public-private data exchange. The Initial focus is healthcare data and telemedicine, which has been granted 5 million DDK in seed funding from the Danish Industry Foundation. The project will show how a combination of so-called zero-knowledge technologies (such as secure multiparty computation) and traditional blockchain technologies provide a better platform for transparent and yet privacy-preserving use of confidential data. SECATA works closely together with Data Fair, the Alexandra Institute and the Data for Good Foundation, about developing a fully compliant public-private infrastructure for citizen-centric data exchange.

SECATA is a spinout from Partisia dedicated to developing MPC based applications.

Sepior – a Partisia spinout – is developing a pure cloud solution for cryptographic key management. In close collaboration with a strong team of investors and experienced entrepreneurs, Sepior has raised approximately DKK 25 million in seed money from investors, a grant from the Danish market development fund and not least a SME instrument Phase 2 grant.

While strong encryption is a crucial component in solving cloud security, the problem of proper key management in the cloud remains. Sepior is solving this critical problem in a fundamental new way using Secure Multiparty Computation (MPC). The initial investments and grants, will be used by the Sepior team to turn Sepior and the product Sepior Key Management into a scalable and profitable business.

Partisia is one of the beneficiaries in the SME instrument phase 2 grant and user of the Sepior Key Management.

Secure Multiparty Computation Goes Live


In close cooperation with the Danish sugar industry, the Partisia team developed a secure exchange (also called a double auction) based on Secure Multiparty Computation (MPC). The exchange was the world’s first large scale application and commercial use of MPC. The solution has been used frequently since 2008.

The Partisia Contract Exchange help the Danish sugar industry (including Danisco one of the largest Danish companies at the time) adjust to the changing market situation with a price drop of approximately 40%.

The successful use of MPC was the starting point of Partisia and has been reported in the landmark paper “Secure Multiparty Computation Goes Live” from Financial Cryptography 2009.

case_contract-exhange – a Partisia spinout – is an automated end-to-end auction broker using a Secure Multiparty Computation (MPC) based auction. In close cooperation with experts in energy trade, Partisia has developed a cloud solution based on MPC. The solution is the world’s first commercial cloud solution based on MPC.

The solution consists of two services: The Power Procurement and The Energi Saving Auction solutions. Both services make it simple to run professional procurement auctions and are tailored to Small and Medium sized Entreprises (SMEs).

The Power Procurement solution is basically a trustworthy “middleman”, simplifying the procurement and bidding process as well as managing consumption data, auctions and resulting contracts for both buyers and sellers.

Spectrum auctions

In close cooperation with Copenhagen Economics, Partisia has been awarded framework agreements with both the Swedish and the Norwegian Telecommunication Authorities on designing, developing and operating spectrum auctions.

Spectrum auctions is a highly specialiced field on designing advanced auctions used to allocate user rights to certain frequency bands. The state is the seller and since the licenses are prerequisite for a teleoperator, the auction basically forms the entire telecom industry. For that reason, these auctions are also refeered to as high stake auctions.

As an example, Partisia’s High Stake Auction tailored for the Norwegian 1800 MHz Spectrum Auction has been used to trade spectrum rights for a total of NOK 877.983.276 over the course of 7 days and 83 bidding rounds in December 2015.

Better data leads to better service

By computing directly on the encrypted data, the most valuable data may be part collaborative services in a confidential way

Strong security made simple

Strong encryption is the best way to protect data, so by keeping the raw data encrypted at all time, data collaboration becomes simple

Best data require strong security

Typically the most valuable date are also the most sensitive data and data collaboration requires a trustworthy solution.
