The advent of Internet of Things (IoT) brought innovation along with unprecedented benefits of convenience and efficacy in many operations that were otherwise very cumbersome. This innovation explosion has surfaced a new dimension of vulnerability and physical threat to the data integrity of IoT networks. Implementing conventional cryptographic algorithms on IoT devices is not future-proof as these devices are constrained in terms of computational power, performance, and memory. In this paper, we are proposing a novel framework, a unique model that integrates IoT networks with a blockchain to address potential privacy and security threats for data integrity. Smart contracts are instrumental in this integration process and they are used to handle device authentication, authorization and access-control, and data management. We further share a new design model for interfaces to integrate both platforms while highlighting its performance results over the existing models. With the incorporation of off-chain data storage into the framework, overall scalability of the system can be increased. Finally, our research concludes how the proposed framework can be fused virtually into any existing IoT applications with minimal modifications.
物联网 (IoT) 的出现带来了创新，在许多原本非常繁琐的操作中带来了前所未有的便利和效率。这种创新爆炸为物联网网络的数据完整性带来了新的脆弱性和物理威胁层面。在物联网设备上实施传统的加密算法并不是未来的解决方案，因为这些设备在计算能力、性能和内存方面受到限制。在本文中，我们提出了一个新颖的框架，一个独特的模型，将物联网网络与区块链集成在一起，以解决数据完整性方面的潜在隐私和安全威胁。智能合约在这个集成过程中起着重要的作用，用于处理设备认证、授权和访问控制以及数据管理。我们进一步分享了一个新的接口设计模型，用于集成两个平台，同时突出其在现有模型之上的性能结果。通过将链下数据存储纳入框架，系统的整体可扩展性可以提高。最后，我们的研究得出结论，提出的框架可以通过最小的修改，几乎融合到任何现有的物联网应用中。
