“…Blockchain technology is primarily utilized as a tamper-proof platform for IoT data [ 6 , 7 ], especially in wireless sensor networks [ 8 ], to establish data trust [ 9 ]. Numerous papers have reported on the use of blockchain as a security feature for IoT [ 10 , 11 , 12 , 13 ], even in sensitive use cases such as medical [ 14 ] and industrial [ 15 ], where confidentiality, integrity, and data availability must be ensured [ 16 ].…”

Blockchain-based applications necessitate the authentication of connected devices if they are employed as blockchain oracles. Alongside identity authentication, it is crucial to ensure resistance against tampering, including safeguarding against unauthorized alterations and protection against device counterfeiting or cloning. However, attaining these functionalities becomes more challenging when dealing with resource-constrained devices like low-cost IoT devices. The resources of IoT devices depend on the capabilities of the microcontroller they are built around. Low-cost devices utilize microcontrollers with limited computational power, small memory capacity, and lack advanced features such as a dedicated secure cryptographic chip. This paper proposes a method employing a Physical Unclonable Function (PUF) to authenticate identity and tamper resistance in IoT devices. The suggested PUF relies on a microcontroller’s internal pull-up resistor values and, in conjunction with the microcontroller’s built-in analog comparator, can also be utilized for device self-checking. A main contribution of this paper is the proposed PUF method which calculates the PUF value as the average value of many single PUF measurements, resulting in a significant increase in accuracy. The proposed PUF has been implemented successfully in a low-cost microcontroller device. Test results demonstrate that the device, specifically the microcontroller chip, can be identified with high accuracy (99.98%), and the proposed PUF method exhibits resistance against probing attempts.

This chapter comprehensively surveys the six aspects of the 5G and future 6G internet of things (IoT). First, most of the 5G- and 6G-IoT usage scenarios and key performance indicators are summarized in the forms of tables, pictures, and diagrams to facilitate readers to understand and compare current and future IoT technologies more easily and quickly. Second, 5G- and 6G-IoT access networks, protocols, and standards were briefly analyzed and compared, such as coverage, transfer data speed, energy consumption, operating frequency, and the number of device connectivity. Third and fourth, the impact of 6G-IoT on society's daily life and industry operation, as well as its underlying research were described. Fifth, five types of 6G-IoT challenges were analyzed and discussed in detail in this chapter, namely transmission path loss at THz, wireless network coverage, transfer data rate, latency, security, privacy protection, and energy-efficient and reliable devices/services. Finally, the latest nine IoT business models are described and summarized in tabular form.
