The computation efficiency of distributed secure implementation of the computation of a (sum of) products of values Vi, Wi from different servers on a distributed computing system is improved by generation of coefficients of a first polynomial and second polynomial by a first server. The first polynomial P has all numbers Xi from a first data set on the first server as roots. The second polynomial Q has values Q(Xi)=Vi for the numbers Xi from the first data set. The first device transmits coefficients of the first and second polynomial P, Q to a second server in encrypted form. The second sever computes encrypted values and of the first and second polynomial P, Q for a number Xi′ in a second set from the encrypted coefficients. The second server uses a secure multiparty equality protocol to compute an encrypted binary value from the encrypted value and the second server may compute a sum encrypted sum of the products from the encrypted product computed for all of the numbers Xi′ and associated values Wi from the second set.
