The integration of wireless networks and Internet of things (IoT)-enabled communication between smart grid entities to address the challenges in supply chain including mutual authentication and privacy persistence, and control access scheme is critical in smart grids. In the last decade, numerous control access schemes have been presented. However, existing schemes are not reliable in terms of security and privacy and they involve third parties and central management system that leads the smart grid toward untrustworthiness and single-point failure. In addition, smart meters are managed through a central entity called service provider, and due to centralization, it involves single-point failure. Moreover, IoT-based smart meters are vulnerable due to untrusted environment; thus, it requires to establish trusted control access between entities of network to exchange messages. To overcome these issues, this paper proposes a decentralized trusted control access scheme by leveraging blockchain technology to ensure trusted communication between entities of smart grid by protecting data transmission requests which are sent/received by smart meter to network. In conclusion, an analysis in the context of security and performance is presented. The analysis depicts that the proposed scheme is effective in terms of computational and storage cost.

在智能电网实体之间集成无线网络和支持物联网（IoT）的通信，以应对供应链中的挑战，包括相互身份验证和隐私持久性，以及控制访问方案对于智能电网至关重要。在过去的十年中，提出了许多控制访问方案。但是，现有方案在安全性和隐私性方面并不可靠，并且涉及第三方和中央管理系统，这些系统和系统会导致智能电网走向不可信和单点故障。此外，智能电表通过称为服务提供商的中央实体进行管理，由于集中化，它涉及单点故障。此外，基于物联网的智能电表由于不受信任的环境而容易受到攻击。因此，它需要在网络实体之间建立信任的控制访问权以交换消息。为了克服这些问题，本文提出了一种分散化的可信控制访问方案，该方案利用区块链技术来保护智能电表发送/接收到网络的数据传输请求，从而确保智能电网实体之间的可信通信。总之，提出了在安全性和性能方面的分析。分析表明，该方案在计算和存储成本方面是有效的。本文提出了一种分散化的可信控制访问方案，该方案利用区块链技术来保护智能电表发送/接收到网络的数据传输请求，从而确保智能电网实体之间的可信通信。总之，提出了在安全性和性能方面的分析。分析表明，该方案在计算和存储成本方面是有效的。本文提出了一种分散化的可信控制访问方案，该方案利用区块链技术来保护智能电表发送/接收到网络的数据传输请求，从而确保智能电网实体之间的可信通信。总之，提出了在安全性和性能方面的分析。分析表明，该方案在计算和存储成本方面是有效的。
