【摘要】：互联网技术的不断发展推进了各大企业走向信息化时代,越来越多各式各样的系统应运而生。为企业带来巨大便利和利益的同时也带来了一些安全方面的隐患。访问控制的地位日益重要,成为各大系统中不可或缺的部分。 中药溯源系统,通过计算机网络技术将中药药材的种植过程,销售过程进行详细的记录与跟踪。由于中药溯源系统的特殊性,它对用户权限要求更加严格。必须尽可能的降低人为因素造成的干扰,权限控制系统显得愈发重要。传统的基于角色的访问控制(RBAC)模型很难适应中药溯源系统对权限的安全需求。因此,有必要对传统的RBAC模型进行改进,以提高权限管理的灵活性。 本文在开发中药溯源系统的同时,对传统的访问控制相关知识进行了深入的研究,重点分析了传统的RBAC模型,提出了对传统RBAC模型的改进方法。本文的主要内容如下： 1.首先介绍了三种访问控制策略：自主访问控制、强制访问控制和基于角色的访问控制。对比了三者的优缺点,着重介绍基于角色的访问控制策略,确定其更适合中药溯源系统的开发需求。分析了传统的RBAC模型在中药溯源系统中应用的不足,并且给出了相应的解决方案。 2.结合中药溯源系统的使用特点以及RBAC模型的基本原则,引入“对象维度”、“组时间维度”以及“时限自主授权”的概念,并对该改进模型的特点进行阐述。 3.在RBAC改进模型的基础上,设计并将其应用于某中药企业的溯源系统,最后,给出了RBAC改进模型在实际业务系统中的应用效果。
[Abstract]:With the continuous development of Internet technology, more and more kinds of systems emerge as the times require. It not only brings great convenience and benefits to enterprises, but also brings some hidden dangers in security. Access control is becoming more and more important and has become an indispensable part of the major systems. Traceability system of traditional Chinese medicine, through computer network technology, the planting process and sales process of traditional Chinese medicine are recorded and followed in detail. Due to the particularity of the traceability system of traditional Chinese medicine, it requires more strict user rights. The interference caused by human factors must be reduced as much as possible, and the authority control system is becoming more and more important. The traditional role-based access control (RBAC) model is difficult to adapt to the security requirements of the traceability system of traditional Chinese medicine. Therefore, it is necessary to improve the traditional RBAC model in order to improve the flexibility of authority management. In this paper, while developing the traceability system of traditional Chinese medicine, the related knowledge of traditional access control is deeply studied, the traditional RBAC model is analyzed, and the improved method of traditional RBAC model is put forward. The main contents of this paper are as follows: 1. Firstly, three access control strategies are introduced: autonomous access control, mandatory access control and role-based access control. This paper compares the advantages and disadvantages of the three, mainly introduces the role-based access control strategy, and determines that it is more suitable for the development requirements of the traceability system of traditional Chinese medicine. The shortcomings of the traditional RBAC model in the traceability system of traditional Chinese medicine are analyzed, and the corresponding solutions are given. two銆，
