Abstract

The use of blockchain technology has been proposed to provide auditable access control for individual resources. Unlike the case where all resources are owned by a single organization, this work focuses on distributed applications such as business processes and distributed workflows. These applications are often composed of multiple resources/services that are subject to the security and access control policies of different organizational domains. Here, blockchains provide an attractive decentralized solution to provide auditability. However, the underlying access control policies may have event-driven constraints and can be overlapping in terms of the component conditions/rules as well as events. Existing work cannot handle event-driven constraints and does not sufficiently account for overlaps leading to significant overhead in terms of cost and computation time for evaluating authorizations over the blockchain. In this work, we propose an automata-theoretic approach for generating a cost-efficient composite access control policy. We reduce this composite policy generation problem to the standard weighted set cover problem. We show that the composite policy correctly captures all the local access control policies and reduces the policy evaluation cost over the blockchain. We have implemented the initial prototype of our approach using Ethereum as the underlying blockchain and empirically validated the effectiveness and efficiency of our approach. Ablation studies were conducted to determine the impact of changes in individual service policies on the overall cost.

基于区块链的事件驱动政策业务流程可审计访问控制。
有人建议使用区块链技术为单个资源提供可审计的访问控制。与所有资源都由单一组织拥有的情况不同,这项工作侧重于分布式应用,如业务流程和分布式工作流。这些应用通常由多个资源/服务组成,受不同组织域的安全和访问控制策略制约。在此,区块链为提供可审计性提供了一种极具吸引力的去中心化解决方案。然而,底层访问控制策略可能具有事件驱动约束,并且在组件条件/规则以及事件方面可能存在重叠。现有的工作无法处理事件驱动的约束,也没有充分考虑到重叠问题,导致在区块链上评估授权的成本和计算时间大大增加。在这项工作中,我们提出了一种自动机理论方法,用于生成具有成本效益的复合访问控制策略。我们将这种复合策略生成问题简化为标准的加权集覆盖问题。我们证明,复合策略能正确捕获所有本地访问控制策略,并降低区块链上的策略评估成本。我们使用以太坊作为底层区块链实现了我们方法的初始原型,并通过实证验证了我们方法的有效性和效率。我们进行了消融研究,以确定单个服务策略的变化对总体成本的影响。
