Deploying Secure Multi-Party Computation for Financial Data Analysis - (Short Paper)
We show how to collect and analyze financial data for a consortium of ICT companies using secret sharing and secure multiparty computation (MPC). This is the first time where the actual MPC computation on real data was done over the internet with computing nodes spread geographically apart. We describe the technical solution and present user feedback revealing that MPC techniques give sufficien...

In this paper, a new broadcast encryption scheme is presented based on threshold secret sharing and secure multiparty computation. This scheme is maintained to be dynamic in that a broadcaster can broadcast a message to any of the dynamic groups of users in the system and it is also fair in the sense that no cheater is able to gain an unfair advantage over other users. Another important feature...

In secure multiparty computation (SMC), a group of users jointly and securely computes a mathematical function on their private inputs, such that the privacy of their private inputs will be preserved. One of the widely used applications of SMC is the secure multiparty summation which securely computes the summation value of the users’ private inputs. In this paper, we consider a secure multipar...
متن کاملSecure Multiparty Computation for Privacy-Preserving Data Mining
In this paper, we survey the basic paradigms and notions of secure multiparty computation and discuss their relevance to the field of privacy-preserving data mining. In addition to reviewing definitions and constructions for secure multiparty computation, we discuss the issue of efficiency and demonstrate the difficulties involved in constructing highly efficient protocols. We also present comm...
متن کاملSecure Multiparty Computation
Assume a number of parties want to compute a public function F (x1, . . . , xn) = (y1, . . . , yn). All of them want to get the correct answer, but none of them are willing to expose their secret inputs to other parties. One way to achieve this requirement is to implement the secure multiparty computation protocols. In this paper, we will make a brief introduction to secure multiparty computati...
