“…TinyIPFIX has a similar purpose to other protocols in the IoT domain, such as HTTP, Constrained Application Protocol (CoAP), or message queuing telemetry transport (MQTT). TinyIPFIX [8] has less overhead than IPFIX due to the introduction of (1) template and data messages, similar to IPFIX as well as (2) in-network aggregation [12]. There are several implementations of TinyIPFIX [8,13,14] provided in the literature.…”

“…Furthermore, this work deploys the tiny Internet protocol flow information export (TinyIPFIX) [7], which sends metadata and actual sensor data in separate messages and decreases the communication overhead and energy cost in comparison to other protocols in this domain. As a result, TinyIPFIX enables WSNs' operation to run longer on a single battery charge than regular application protocols, such as message queuing telemetry transport (MQTT) or hypertext transfer protocol (HTTP) [8,9].…”

While wireless sensor networks (WSN) offer potential, their limited programmability and energy limitations determine operational challenges. Thus, a TinyIPFIX-based system was designed such that this application layer protocol is now used to exchange data in WSNs efficiently. The new prototype is based on the Espressif ESP32-WROOM-32D Internet-of-Things (IoT) platform, which is becoming famous, as it is inexpensive but powerful compared to older generations of IoT devices. The system implementation is provided in the programming language MicroPython, which provides a simple and efficient implementation, compared to a lower-level programming language. Therefore, this approach focuses on value creation rather than platform-specific implementation difficulties. The system is evaluated in smart home use cases and displays valuable overhead, reliability, and power efficiency. TinyIPFIX outperforms the data overhead of the type–length–value (TLV) paradigm by a factor of 7% when a TinyIPFIX data message carries only two records, and one TinyIPFIX template message is sent per three TinyIPFIX data messages. A further decrease in overhead is observed when the number of data records per message and the number of TinyIPFIX data messages sent per one TinyIPFIX template message increase to larger values. The message delivery between end devices and the application server resides at a very high level, close to 100%, when the transmission reliability is secured with acknowledgments and retransmissions. The energy efficiency resides at the limited level, as the experienced deep sleep power consumption of the ESP32 device resides at the milliwatt level.

“…Also, in platforms without TPM, the authors found that ECC implementations require significantly less resources than when using RSA. The authors analyze the resource requirements of a DTLS implementation using ECC, and integrated RSA and ECC-based DTLS with the TinyIPFIX [87] protocol for usage in a building automation application scenario, but however verified that the proposed implementation still requires more resources than with less resourceful devices.…”

A Survey of Key Bootstrapping Protocols Based on Public Key Cryptography in the Internet of Things

The Internet of Things envisages connecting all physical objects or things to the Internet, using devices as diverse as smartphones, coffee makers, washing machines, automobiles, lamps, and wearable devices, among many others. The explosive growth of Internet-connected sensing and actuating devices has bridged the gap between the physical and the digital world, with new solutions bringing benefits to people, processes, and businesses. However, security will be a major challenge in enabling most of such applications. The lack of secure links exposes data exchanged by devices to theft and attacks, with hackers already showing a keen interest in this area. Secure communication in the IoT will require a multifaceted approach, in particular, targeting aspects as relevant as the communications' protocols and data that need to be secured. One of the major aspects among these is how keys are bootstrapped in devices, for the purpose of supporting secure communications. In this paper, we survey the state of the art in key bootstrapping protocols based on public-key cryptography in the Internet of Things. Due to its inherent scalability, such protocols are particularly relevant for the implementation of distributed identity and trust management mechanisms on the IoT, in the context of which devices may be authenticated and trusted. The reviewed proposals are analyzed and classified on the basis of the key delivery method, the underlying cryptographic primitive, and the authentication mechanism supported. We also identify and discuss the main challenges of implementing such methods in the context of IoT applications and devices, together with the main avenues for conducting further research in the area.

“…In many CPS scenarios [ 79 , 80 ], other technologies such as XML or JSON are preferred, as they are also efficient, human readable and can also be transmitted via HTTP. However, this is not possible with the selected hardware (which only has 2 KB of SRAM and 30 KB available in EEPROM).…”

Nowadays, manufacturing processes have become highly complex. Besides, more and more, governmental institutions require companies to implement systems to trace a product’s life (especially for foods, clinical materials or similar items). In this paper, we propose a new framework, based on cyber-physical systems, for developing traceability systems in small manufacturing companies (which because of their size cannot implement other commercial products). We propose a general theoretical framework, study the requirements of these companies in relation to traceability systems, propose a reference architecture based on both previous elements and build the first minimum functional prototype, to compare our solution to a traditional tag-based traceability system. Results show that our system reduces the number of inefficiencies and reaction time.
