本文提出了一种基于CP-ABE的端到端安全数据交换系统,用于解决价值链中敏感数据保护与动态访问策略更新问题,并通过实验验证了其在资源受限的IIoT平台上的可行性。

摘要:

价值链合作伙伴之间的数据交换为其提供了竞争优势,但暴露敏感数据的风险也在不断增加。信息在存储和传输过程中必须受到保护以降低这一风险,因此只有数据生产者和最终消费者能够访问或修改数据。端到端(E2E)安全机制应对了这一挑战,保护企业免受价值链攻击所导致的数据泄露。此外,还必须考虑价值链的特殊性。在这种动态环境中,数据生成和消费都涉及多个实体。因此,需要灵活生成访问策略,以确保策略能够在需要时随时更新。本文提出了一种依赖CP-ABE的、具有E2E安全性的价值链数据交换系统。该系统考虑了价值链中最相关的安全和工业需求。所提出的解决方案能够根据访问策略保护数据,并在不破坏E2E安全性或不过度增加现场设备负担的情况下更新这些策略。在大多数情况下,现场设备是IIoT设备,其处理和存储能力有限。实验评估表明,所提出的解决方案在IIoT平台上具有可行性。

英文摘要:

Data exchange among value chain partners provides them with a competitive advantage, but the risk of exposing sensitive data is ever-increasing. Information must be protected in storage and transmission to reduce this risk, so only the data producer and the final consumer can access or modify it. End-to-end (E2E) security mechanisms address this challenge, protecting companies from data breaches resulting from value chain attacks. Moreover, value chain particularities must also be considered. Multiple entities are involved in dynamic environments like these, both in data generation and consumption. Hence, a flexible generation of access policies is required to ensure that they can be updated whenever needed. This paper presents a CP-ABE-reliant data exchange system for value chains with E2E security. It considers the most relevant security and industrial requirements for value chains. The proposed solution can protect data according to access policies and update those policies without breaking E2E security or overloading field devices. In most cases, field devices are IIoT devices, limited in terms of processing and memory capabilities. The experimental evaluation has shown the proposed solution's feasibility for IIoT platforms.
