Abstract

In the process of the development of the socialist market economy, taxes bear the Organization's financial income, to regulate the economy, regulating social distribution functions in China each year for more than 90% of fiscal revenue from taxes, its increasingly important position and role. With the rapid development of the economy, the current system of tax administration in the effective promotion of enterprise accounting properly maintain social and economic order, control sources of revenue, plug the collection and management of vulnerability still some problems still exist. The same time, the authenticity, validity of the tax data has been one of the difficulties of restricting tax information construction of the development process, especially the security issues of the invoice data is particularly prominent, there is an urgent need to address this issue with the appropriate technical means to further push forward the development of the Fiscal reform. Password technology has undergone years of development, has formed a relatively complete system, especially the emergence of non-symmetric algorithm to solve the problem of some long-troubled people. Reasonable Fiscal cryptographic techniques used in the field of security and can achieve the purpose of the invoice data forgery. This thesis, starting from the tax control requirements for anti-counterfeiting technology, explore cryptographic techniques, especially asymmetric cryptographic techniques used in the feasibility of tax control security field, symmetric algorithms and asymmetric algorithms applied to the tax control security field combination . This article focuses on the cryptographic algorithms used in the field of tax control anti-counterfeiting, key distribution and management, tax control, anti-counterfeiting security system design problem Fiscal anti-counterfeiting and security risk for the entire security system may face and the The security measures taken in the analysis and elaboration. The security algorithms discussed in this paper system and tax control anti-counterfeiting security system, we design and develop a set Fiscal forgery management systems and dedicated cryptographic device. The whole system is divided into two parts, respectively, of the the tax industry clients and central office (the tax authorities end) Fiscal encryption boxes and verification server as each core safety equipment, these two devices can only complete each generation security code and verification security code function, a fundamental guarantee for the equipment can not be abused. In addition, as the security code of the security infrastructure of the entire system to generate algorithms - short ciphertext asymmetric algorithms, have generated ciphertext short (8 bytes), security and high intensity, very suitable for the requirements of the invoice data forgery, but also the entire tax control anti-counterfeiting a significant feature of the method. The first large-scale application in the land tax system in China based on the security algorithm and security system of tax control anti-counterfeiting system, made very significant tax-increase the effect of a land tax Fiscal forgery positive and effective try and push forward the development of China's Fiscal forgery career. The entire system and related safety equipment discussed in this paper by the national technical appraisal, in full compliance with China's password management system.
