这项工作提供了一个可持续的网络安全解决方案，使用物理不可克隆功能(PUF)、可信平台模块(TPM)和Tangle分布式分类帐技术(DLT)来实现可持续的设备和数据安全。由于硬件辅助密码解决方案对防篡改存储的需求，设计安全(SBD)或硬件辅助安全(HAS)解决方案已变得非常突出。由于物联网应用更加分散，设计复杂的安全机制可能会影响其效率。在提出的体系结构中，我们提出了一种新的支持TPM的基于PUF的安全机制，有效地集成了PUF和TPM。所提出的机制基于在TPM中密封PUF密钥的过程，该PUF密钥不能在TPM之外被访问，并且只能由TPM本身来解封。指定的NV索引被分配给每个物联网节点，用于使用媒体访问控制(MAC)地址将PUF密钥密封到TPM。对TPM的非易失性随机存取存储器(NVRAM)的访问由信任计算组(TCG)指定的TPM的增强授权策略定义。提出的体系结构使用Tangle来实现可持续的数据安全和存储，通过掩蔽认证消息(MAM)方案来实现对Tangle的高效和安全的访问控制。我们通过实验分析和实现验证了所提出的方法，证实了所提出的PUFchain 4.0在分散式物联网驱动的安全解决方案中的潜力。
This work presents a sustainable cybersecurity solution using Physical Unclonable Functions (PUF), Trusted Platform Module (TPM), and Tangle Distributed Ledger Technology (DLT) for sustainable device and data security. Security-by-Design (SbD) or Hardware- Assisted Security (HAS) solutions have gained much prominence due to the requirement of tamper-proof storage for hardwareassisted cryptography solutions. Designing complex security mechanisms can impact their efficiency as IoT applications are more decentralized. In the proposed architecture, we presented a novel TPM-enabled PUF-based security mechanism with effective integration of PUF with TPM. The proposed mechanism is based on the process of sealing the PUF key in the TPM, which cannot be accessed outside the TPM and can only be unsealed by the TPM itself. A specified NV-index is assigned to each IoT node for sealing the PUF key to TPM using the Media Access Control (MAC) address. Access to the TPM's Non-Volatile Random Access Memory (NVRAM) is defined by the TPM's Enhanced Authorization policies as specified by the Trust Computing Group (TCG). The proposed architecture uses Tangle for sustainable data security and storage in decentralized IoT systems through a Masked Authentication Messaging (MAM) scheme for efficient and secure access control to Tangle. We validated the proposed approach through experimental analysis and implementation, which substantiates the potential of the presented PUFchain 4.0 for decentralized IoT-driven security solutions.
