【摘要】 随着税收信息化的发展,网上税收业务也得到了蓬勃发展,网上申报作为税务系统网上业务的重要组成部分,安全性的要求往往都是很高的,而税收是国家财政的主要来源,税务系统担负着为国聚财的重任。因此,对税务系统来说,网上申报系统的安全性要求更是非同寻常。本文首先讨论当前网上申报模式、申报流程等,并根据申报模式、数据流程分析研究存在的弱点,在第三部分引入安全隔离网闸(GAP)概念,并研究安全隔离网闸(GAP)在网上申报系统中的实现;在第四部分重点研究网上申报系统中数据的保密性、完整性和不可否认性,引入PKI(公钥基础设施)概念,并研究PKI在网上申报系统中的应用与实现。本文通过分析网上申报弱点,引入安全隔离网闸(GAP)、PKI系统等,为税务系统网上业务安全提供更好的安全保障。
