XACML 정책 작성시 요청에 따른 정책 평가 요인을 수집하기 위한 사례 연구

초록

As the Internet of Things environment continues to expand, access control issues continue to emerge. OneM2M, one of the standards of the IOT platform, allows access control using XACML. In the arena of access control, conflicts must be solved. Because of this, various solutions are being investigated in order to solve these problems. Currently, however, the policy editor must solve policy conflicts by themselves. So, the policy editor needs to be able to effectively collect information about policies and conditions that affect their policy evaluation decisions in order to resolve policy conflicts. In this paper, we analyze policy and express policy evaluation methods in terms of Truth Table. In addition, we present a tree-based policy evaluation factor collection method through a case study on a policy evaluation factor collection method according to requests using Truth Table.
