On the (Im)possibility of privately outsourcing linear programming

Author Laud, Peeter Pankova, Alisa
Abstract In this paper we study the security definitions and methods for transformation-based outsourcing of linear programming. The recent attacks have shown the deficiencies of existing security definitions; thus we propose a stronger, indistinguishability-based definition of security of problem transformations that is very similar to IND-CPA security of encryption systems. We will study the realizability of this definition for linear programming and find that barring radically new ideas, there cannot exist transformations that are secure information-theoretically or even computationally. We conclude that for solving linear programming problems in privacy-preserving manner, cryptographic methods for securely implementing Simplex or some other linear programming solving algorithm are the only viable approach.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
