Dynamic Multi-party Computation Forever for Swarm and Cloud Computing and Code Obfuscation

摘要

Intuitive and Basic Description of Secure Multi-party Computation. Secure multi-party computation [1,3] schemes allow participants to calculate a function of their inputs, such that the inputs of the participants are not revealed to each other. An important building block in secure multi-party computation is secret sharing [11]. In secret sharing each participant (with identifier) i gets the value f(i) = y of a polynomial function f of degree t over a finite field. The secret is the value of the function f in zero, namely f(0), which is a value in the finite field over which f is denned.
