摘要
函数秘密共享是秘密共享的一种扩展,它能够在不泄露秘密函数的前提下对秘密函数在公开输入上的函数值进行安全计算.由于函数秘密共享技术具有非交互的性质以及出色的性能,近年来广受国内外研究者的关注.本文从函数秘密共享的概念、构造以及应用等角度深入研究现有的函数秘密共享方案.首先,描述了函数秘密共享的基本概念,给出具有代表性的函数秘密共享方案并深入分析典型方案的底层技术原理;其次,对目前函数秘密共享技术的研究路线进行梳理并提炼核心思路,对目前函数秘密共享的主流应用进行分类,阐述函数秘密共享在不同应用场景下的基本使用方法以及在各类应用中的优势和性能表现;最后,总结函数秘密共享技术的优缺点、适用场景、存在的问题和未来发展方向.
Abstract
Function secret sharing is an extension of secret sharing that enables secure evaluation of the secret function on public inputs.Due to its non-interactive property and excellent performance,function secret sharing technology has attracted wide attention from researchers worldwide in recent years.This paper presents a comprehensive analysis of current function secret sharing schemes re-garding their concept,construction,and applications.First,the concept of function secret sharing is described.A representative scheme is introduced,and its underlying technical mechanisms are an-alyzed in detail.Second,the research directions of function secret sharing technology are reviewed and the core ideas are extracted.Additionally,the mainstream applications of function secret sharing are categorized,explaining the basic deployment methods,advantages,and performance in various application scenarios.Finally,the strengths and weaknesses,applicable scenarios,existing problems,and future directions of function secret sharing technology are summarized.
