Blockchain plays a vital task in cybersecurity. With the exerted efforts for realising large-scale quantum computers, most current cryptographic mechanisms may be hacked. Accordingly, we need a quantum tool utilised for designing blockchain frameworks to have the ability to be executed in the level of digital computers and resist the probable attacks from both digital and quantum computers. Quantum walks may be utilised as a quantum-inspired model for designing new cryptographic algorithms. In this paper, we present a new authentication and encryption protocol based on quantum-inspired quantum walks (QIQW). The proposed protocol is utilized to build a blockchain framework for secure data transmission among IoT devices. Instead of using classical cryptographic hash functions, quantum hash functions based on QIQW are employed for linking blocks of the chain. The main advantages of the presented framework are helping IoT nodes to effectively share their data with other nodes and full control of their records. Security analysis demonstrates that our proposed protocol can defend against message attack and impersonation attacks, thus ensuring secure transmission of data among IoT devices.

区块链在网络安全中扮演着至关重要的任务。随着实现大规模量子计算机的努力，大多数当前的加密机制可能会被黑客入侵。因此，我们需要一种用于设计区块链框架的量子工具，使其具有在数字计算机级别上执行并抵御来自数字计算机和量子计算机的可能攻击的能力。量子游走可用作设计新密码算法的量子启发模型。在本文中，我们提出了一种新的基于量子启发式量子步态（QIQW）的身份验证和加密协议。拟议的协议用于构建用于IoT设备之间安全数据传输的区块链框架。与其使用经典的密码散列函数，基于QIQW的量子哈希函数被用于链接链的块。提出的框架的主要优点是帮助IoT节点与其他节点有效共享其数据并完全控制其记录。安全分析表明，我们提出的协议可以抵御消息攻击和模拟攻击，从而确保在IoT设备之间安全地传输数据。
