“…Now, EPCGlobal's IoT architecture is the most representative of the well-known IoT architecture. Its main components are EPC coding technology, EPC tags, EPC readers, ONS servers and EPC middleware [12]. Due to the different capabilities of the IoT system architecture, it can be divided into three levels: the perception level, the lower level used to collect information, and the network level, which also belongs to the middle level grade.…”

Networking is one of the new technologies supported by our country’s national “125” strategic industry plan, mainly used in medicine, military industry, transportation and other fields. While enjoying the convenient business of the, people also pay more attention to the security of the Internet of Things information system. Therefore, this article mainly discusses security under the perspective of the IoT, and understands the relevant basic theoretical knowledge about the IoT and security on the basis of a large number of documents, and then conceives the security methods under the perspective of the IoT, and the designed method has been tested, and the test results show that the performance of the encryption algorithm in the network security scheme of this article is due to the traditional encryption algorithm. When the encrypted text is 15000 bytes, the encryption time is 40s.

“…More crucially, since the PUF can generate the chip-specific secret via a unique response that is only generated upon request by providing a challenge, there is no need to keep a secret Key locally on a device. These characteristics make PUF an excellent choice for IoT devices with minimal resources [17].…”

The Internet of Things (IoT) is rapidly becoming a common technology that will improve people's lives by seamlessly integrating into many facets of modern life and facilitating information sharing across platforms. Device Authentication is a significant challenge for IoT devices as they are placed in unprotected environments, vulnerable to physical attacks and common security risks. Large computational requirements and communication costs during Authentication make the existing methods, like Public Key Cryptography and Identity-based Encryption, unsuitable for resource-constrained IoT devices. Physical Unclonable Function (PUF) offers a lightweight security mechanism instead of traditional sophisticated cryptosystems by providing an unclonable and tamper-sensitive unique signature. Therefore, we use lightweight operations like bitwise XOR, hash function, and PUF, suitable for resource-constrained IoT devices to authenticate IoT devices. Despite several studies employing the PUF, to the authors' knowledge, existing solutions require an intermediary verifier/gateway and/or active internet by the IoT device to directly interact with a Server to authenticate itself and, hence, are not scalable when the IoT device works technologies like Bluetooth Low Energy, Zigbee, etc. To address the aforementioned issue, we present a system in which the IoT device does not require an active internet connection to communicate with the server. The results of a thorough security study are validated against adversarial attacks and PUF-modelling attacks. For formal security validation, the AVISPA verification tool is also used. Performance study recommends this protocol's lightweight characteristics. The proposed protocol's acceptability and defenses against various adversarial assaults are supported by a prototype developed with ESP32.

Due to the 4th industrial revolution and the strength of the 5 th Generation (5G) era, the Internet of Things (IoT) industry is growing significantly. As a result, the number of IoT devices in various industries, such as smart cars, smart homes, and smart healthcare, and the importance of security for these devices are increasing. This study proposes a design method for a secure cryptographic system on a chip (SecSoC) that can be used in the IoT industry and presents the results of the performance and security evaluations of the implemented chipset. The experimental results demonstrated that the SecSoC is a low-power highperformance cryptographic chip that is safe from external attacks. Compared to conventional smart card integrated circuits, the proposed design includes intrusion detection circuits that can respond to external attacks. At the same time, it supports a physical unclonable function for hiding secret data and cryptographic logic for maintaining integrity and confidentiality. The SecSoC ensured a fast transfer rate up to 110 Mbps and consumed only 95.8 mW when operating at maximum frequency.
