论文摘要
在行业4.0制造业中，协作生产和动态选择的生产伙伴的动态选择会导致公司之间的自动数据交换。自动且无监督的数据交换会创建新的攻击向量，恶意内部人士可以使用该攻击媒介通过其他人注意到的情况下通过本来被认为的安全渠道泄漏秘密。在本文中，我们反思了通过区块链技术防止秘密数据暴露的方法，同时还提供了可审核的数据交换证明。我们表明，以前基于区块链的隐私保护方法提供保护，但将数据控制给（可能不值得信赖的）第三方，这也可以被视为侵犯隐私的行为。本文采用的方法不利用集中数据存储来进行数据。它实现了在区块链智能合约中P2P通信和数据处理的数据机密性。
Increased collaborative production and dynamic selection of production partners within industry 4.0 manufacturing leads to ever-increasing automatic data exchange between companies. Automatic and unsupervised data exchange creates new attack vectors, which could be used by a malicious insider to leak secrets via an otherwise considered secure channel without anyone noticing. In this paper we reflect upon approaches to prevent the exposure of secret data via blockchain technology, while also providing auditable proof of data exchange. We show that previous blockchain based privacy protection approaches offer protection, but give the control of the data to (potentially not trustworthy) third parties, which also can be considered a privacy violation. The approach taken in this paper is not utilize centralized data storage for data. It realizes data confidentiality of P2P communication and data processing in smart contracts of blockchains.
