The rise of Non-Fungible Tokens (NFTs) and Internet of Things (IoT) devices created new demands for secure data management. To address these needs, we propose LIBLO, a lightweight blockchain-based smart NFT architecture designed for decentralized environments with limited resources. Traditional models mostly depend on heavy computation techniques to ensure the data security. To avoid this, LIBLO introduces a compressed blockchain layer combined with lightweight encryption techniques. This allows secure storage, verification, and controlled access to IoT-generated data without overloading devices. In this architecture, LIBLO acts as a trusted digital framework that securely encapsulates metadata, ownership identity, and access control policies. Each transaction is verified through digital signatures and efficiently recorded on a compressed blockchain ledger. This design ensures privacy, traceability, and integrity and also contributes to energy-efficient implementation in real-time IoT scenarios. Experimental results demonstrate that the suggested LIBLO achieves high encryption strength and strong decryption accuracy of 0.96%, and low error rates of (1.1%). By simplifying cryptographic operations and reducing blockchain complexities, LIBLO presents a practical and adaptable solution for securing digital assets and IoT interactions in smart environments.
非同质化代币（NFT）和物联网（IoT）设备的兴起对安全数据管理提出了新的要求。为满足这些需求，我们提出了LIBLO，这是一种基于区块链的轻量级智能NFT架构，专为资源有限的去中心化环境设计。传统模型大多依赖繁重的计算技术来确保数据安全。为避免这种情况，LIBLO引入了一个压缩区块链层，并结合了轻量级加密技术。这使得在不使设备过载的情况下，能够对物联网生成的数据进行安全存储、验证和受控访问。在这种架构中，LIBLO充当一个可信的数字框架，安全地封装元数据、所有权身份和访问控制策略。每笔交易都通过数字签名进行验证，并高效地记录在一个压缩区块链账本上。这种设计确保了隐私性、可追溯性和完整性，也有助于在实时物联网场景中实现节能。实验结果表明，所提出的LIBLO实现了0.96%的高加密强度和强解密精度，以及1.1%的低错误率。通过简化加密操作和降低区块链复杂性，LIBLO为智能环境中的数字资产安全和物联网交互提供了一个实用且适应性强的解决方案。
