Feasibility and Rate of Secure Non-Interactive Simulations

Secure non-interactive simulations are an important area of study in the field of secure computation. In this article, we will explore the feasibility and rate of secure non-interactive simulations, focusing on the CQ non-interactive simulation model.

Introduction

Secure computation is a field of study that deals with the problem of computing a function securely, even when the inputs to the function are private. One approach to secure computation is the pre-processing model, which involves two phases: the applied phase and the online phase.

Motivation for Studying Secure Non-Interactive Simulations

The online phase of the pre-processing model is fast and achieves information-theoretic security. However, it requires well-structured calculations, which can be expensive to generate. One solution to this problem is to transform cheap correlations into well-structured ones non-interactively and efficiently. This is the motivation behind the CQ non-interactive simulation model.

Pre-Processing Model in Secure Computation

In the pre-processing model, private knowledge is correlated to parties in the applied phase, which is independent of the functions and input of the secure computation performance online phase.

Two Phases of Pre-Processing Model

The online phase of the pre-processing model is fast and achieves information-theoretic security. However, it requires well-structured calculations, which can be expensive to generate.

Concerns with Online Phase of Pre-Processing Model

The online protocol needs very well-structured calculations, and generating well-structured correlations is very expensive. If the online protocol uses some cheap correlations, like some nice correlations, then the online protocol is usually slow.

Solutions to the Concerns with Online Phase

One solution to the concerns with the online phase is to transform cheap correlations into well-structured ones non-interactively and efficiently. This is the motivation behind the CQ non-interactive simulation model.

Introduction to CQ Non-Interactive Simulation Model

The CQ non-interactive simulation model is a new model for secure non-interactive simulations. The objective of the model is to simulate a sample of the target distribution from an independent sample of some source distribution.

Objective of CQ Non-Interactive Simulation Model

The objective of the CQ non-interactive simulation model is to simulate a sample of the target distribution from an independent sample of some source distribution.

Security Conditions of CQ Non-Interactive Simulation Model

The security conditions of the CQ non-interactive simulation model are Based on the universal composable security by K. The model is secured in corrupt analysis if the distributions of at least sample condition on fixing the output is rightly independent of the top output. Similarly, it is secured in corrupt Bob if the distribution of both samples condition on fixings outputs is rapidly independent of Alice output.

Feasibility and Rate of Secure Non-Interactive Simulations

To study the rate of secure non-interactive simulations, we consider m independent samples of some target distribution. The rate of this simulation is the maximum achievable ratio n by m.

Impossibility of Binary Eraser Source from Binary Symmetric Source

It is impossible to simulate a binary eraser source from a binary symmetric source of life process.

Impossibility of Binary Symmetric Source from Binary Eraser Source

In our setting, with the security conditions, We Are able to Show that it is impossible to simulate a binary symmetric source from a binary eraser source.

Feasibility of Binary Symmetric Source from Another Binary Symmetric Source

We show that it is feasible to simulate a binary symmetric source from another binary symmetric source if the maximal correlation of the target distributions is the power of the maximal correlations of the source distribution.

Linear and Non-Linear Reduction Functions

Linear reduction functions achieve the rate half, but non-linear reduction functions can achieve a higher rate.

Conjecture Related to Harmonic Analysis

We have a conjecture related to harmonic analysis that, if proven, would help us put the rate results for statistical gains.

Connection between Secure Simulations and Distance Invariant Codes

There is a connection between secure simulations and distance invariant codes. If the distance enumerators of any good word in the image of the reduction function f are identical, then it is possible to simulate a binary symmetric source from another binary symmetric source.
