PROJECT STATUS: Completed START: January 2006 COMPLETED: March 2009

Secure Information Management and Processing 

ProjektbeskrivelseProject description

 
SIMAP – Secure Information Management and Processing – has provided general and specific solutions to the fundamental problem of sharing secret knowledge without compromising the secrets.  

In many situations it is highly valuable to keep private information secret, and confidentiality and security is therefore a top priority. On the other hand the combination of private information from different sources can be just as valuable. How can this combination be realised without compromising individual privacy? 

The project covered basic research and running prototypes and has set new standards for how securely and efficiently secret information can be shared.

ForskningsresultaterResearch results

 
The primary research result of the project is the world’s first practical application of Secure Multiparty Computation. This is described in this article:

ForretningsresultaterBusiness results

 
The applications are wide-ranging and have the potential to include all situations where secret information is involved.

Examples are coordination of personal information from different sources (databases), benchmarking of industries for learning or motivational purposes, or auctions where the coordination of private information contributes to fixing the right allocation and price of the commodities for sale.

The project has led to the establishment of a spin-off company, Partisia Market Design, co-owned by the Alexandra Institute.

Teknologi og metoderTechnology and methods

 
Photo: The SMC technology used in the SIMAP project requires that multiple keys are in use simultaneously in order that the calculating engine can process encrypted values.

SIMAP provides general and specific solutions to the fundamental problem of sharing secret knowledge without compromising the secrets. This is done in a close cooperation between three fields of research: 

1) Cryptology, which provides the technical foundation,

2) Information economics, which provides a theoretical description of the applications, 

3) Programming languages, which ties together cryptology and information economics, thus making it easier to apply cryptographic primitives to realise the desired use in running software – in a secure manner.

The project ranges from basic research to running prototypes and sets new standards for how securely and efficiently secret knowledge can be shared.
