摘要

基于角色的访问控制(RBAC)系统面临着一个与用户访问请求的系统处理相关的基本问题，即用户身份验证查询(UAQ)问题。在本文中，我们证明了在保证访问请求和动态职责分离关系下，使用无监督机器学习可以解决UAQ问题。使用聚合层次聚类不仅提高了效率，而且避免了现有角色的无序合并以创建新角色，并避免了重复。该算法的时间复杂度为0 (n^3)，是目前最快速、最有前途的模型之一。将该模型与现有模型进行了比较，并进行了实验验证。

An Efficient Solution to User Authorization Query Problem in RBAC Systems Using Hierarchical Clustering

Role Based Access Control (RBAC) systems face an essential issue related to systematic handling of users’ access requests known as the User Authentication Query (UAQ) Problem. In this paper, we show that the UAQ problem can be resolved using Unsupervised machine learning following the guaranteed access request and Dynamic Separation of Duty relations. The use of Agglomerative Hierarchical Clustering not only improves efficiency but also avoids disordered merging of existing roles to create new ones and steers clear of duplication. With a time complexity of O(n^3), the algorithm proves to be one of the fastest and promising models in state-of-the-art. The proposed model has been compared with the existing models and experimentally evaluated.

期刊介绍： Journal of Cyber Security and Mobility is an international, open-access, peer reviewed journal publishing original research, review/survey, and tutorial papers on all cyber security fields including information, computer & network security, cryptography, digital forensics etc. but also interdisciplinary articles that cover privacy, ethical, legal, economical aspects of cyber security or emerging solutions drawn from other branches of science, for example, nature-inspired. The journal aims at becoming an international source of innovation and an essential reading for IT security professionals around the world by providing an in-depth and holistic view on all security spectrum and solutions ranging from practical to theoretical. Its goal is to bring together researchers and practitioners dealing with the diverse fields of cybersecurity and to cover topics that are equally valuable for professionals as well as for those new in the field from all sectors industry, commerce and academia. This journal covers diverse security issues in cyber space and solutions thereof. As cyber space has moved towards the wireless/mobile world, issues in wireless/mobile communications and those involving mobility aspects will also be published.
