【摘要】：信息安全是互联网时代不可回避的问题。近两年来,河南省住建厅建设了河南省建筑市场监管暨一体化平台,旨在对建筑市场行为进行规范化和信息化监管,因此,监管平台的安全机制研究与设计显得尤为重要。为解决河南省建筑市场监管平台的安全问题,本文针对监管平台的安全需求,通过改进RSA算法和Ukey加密锁身份认证机制,以及基于ARBAC97的改进权限控制方案,实现了监管平台安全机制的设计,并应用于河南省建筑市场监管平台。本文分析了RSA加密算法和访问控制模型的国内外现状,针对建筑市场监管平台的安全需求,设计了建筑市场监管平台安全机制的整体架构,确保了监管平台的安全运行。本文主要研究内容如下:1.通过对监管平台的安全需求及体系结构的分析,设计了整体安全机制方案,并详细论述了加密、访问控制、Ukey认证机制,同时分析了整体安全架构的运行机理。2.针对M.Thangavel提出的改进RSA算法密钥生成效率慢问题,对应用较为广泛的Solovay-Strassen和MillerRabin素性测试算法进行了分析与比较,提出了综合的素性测试算法,并与原有RSA算法进行比较,仿真结果表明,综合素性测试算法使得改进的RSA算法运算速率提升了21%以上。3.将改进的RSA算法应用于省建筑市场监管平台。为平台配置了UKey锁,设计了Ukey锁的驱动程序,并将本文算法固化于Ukey锁的驱动程序中。同时,开发了用户加密锁管理系统,设计了监管平台的用户身份认证模块,保证了平台入口用户的合法性。4.针对建筑市场监管平台用户类型繁多、数量巨大的特点,设计了基于ARBAC97模型的改进权限控制方案和对应的数据库,实现了权限控制规则和相应的权限控制系统,保证了监管平台数据资源的灵活授权与管理。应用实践表明,本文设计的安全机制能够很好的满足河南省建筑市场监管平台的安全需求。
[Abstract]:Information security is an unavoidable problem in the Internet age. In the past two years, Henan Provincial Construction Office has built the construction market supervision and integration platform of Henan Province, which aims at standardizing and information-based supervision of construction market behavior. Therefore, the research and design of safety mechanism of the supervision platform is particularly important. In order to solve the security problem of the construction market supervision platform in Henan Province, this paper aims at the security demand of the supervision platform, through improving the RSA algorithm, the authentication mechanism of Ukey encryption lock identity, and the improved authority control scheme based on ARBAC97. The design of safety mechanism of supervision platform is realized, and it is applied to the supervision platform of construction market in Henan province. This paper analyzes the current situation of RSA encryption algorithm and access control model at home and abroad. According to the security requirements of the construction market regulatory platform, the overall structure of the security mechanism of the construction market regulatory platform is designed to ensure the safe operation of the regulatory platform. The main contents of this paper are as follows: 1. Based on the analysis of the security requirements and architecture of the regulatory platform, the overall security mechanism scheme is designed, and the authentication mechanism of encryption, access control and Ukey is discussed in detail. At the same time, the operation mechanism of the overall security architecture is analyzed. Aiming at the problem of slow key generation efficiency of improved RSA algorithm proposed by M.Thangavel, this paper analyzes and compares the widely used Solovay-Strassen and MillerRabin prime test algorithms, proposes a comprehensive primality testing algorithm, and compares it with the original RSA algorithm. The simulation results show that the improved RSA algorithm increases the computing speed by more than 21%. The improved RSA algorithm is applied to the provincial construction market supervision platform. The UKey lock is configured for the platform, the driver of the Ukey lock is designed, and the algorithm of this paper is solidified in the driver of the Ukey lock. At the same time, the user encryption management system is developed, and the user identity authentication module of the supervising platform is designed, which ensures the legitimacy of the platform entrance user. In view of the large number of users in the construction market supervision platform, an improved authority control scheme based on ARBAC97 model and the corresponding database are designed, and the privilege control rules and the corresponding privilege control system are realized. It ensures the flexible authorization and management of the data resources of the supervisory platform. The application practice shows that the safety mechanism designed in this paper can meet the safety requirements of the construction market supervision platform in Henan Province.
