abstract = {Post-Quantum Cryptography (PQC) is a practical and cost-effective solution to defend against emerging quantum computing threats. So, leading worldwide security agencies and standardization bodies strongly advocate for the proactive integration of PQ cryptography into underlying frameworks to support applications, protocols, and services. The current research predominantly addresses the incorporation of PQC in Internet communication protocols such as HTTP and DNS; nevertheless, the focus on embedded devices has been limited to evaluating PQC’s integration within TLS/DTLS in isolation. Hence, there is a notable gap in understanding how PQC impacts IoT-specific communication protocols. This paper presents the integration of PQC into two communication protocols specifically tailored for IoT devices, the Constrained Application Protocol (CoAP) and MQTT for Sensor Networks (MQTT-SN), via the wolfSSL library. These two integrations contribute to the understanding of PQC’s implications for IoT communication protocols.},

abstract = {Internet of Things (IoT) can be defined as the interconnection through Internet of an unprecedented number of devices with the purpose of exchanging data. It stands as one of the most popular technologies for the following years and it is requiring substantial changes in the Internet protocols to meet its requirements. As the application layer is decisive for the quality of the connection, this paper analyzes the performance offered by one of the most popular protocols for the application layer in IoT: the Constrained Application Protocol (CoAP). This analysis aims to examine the features and capabilities of this protocol and to determine its feasibility to operate under constrained devices using security support. For this, a realistic network scenario is deployed to run the simulations and to measure bandwidth, consumption of resources (i.e., CPU cycles and bandwidth usage) and communication latency. Additionally, the trade-off between security and performance is discussed measuring the bandwidth overhead and the consumption increase associated to secure the communications. Different ciphering and authentication algorithms are tested, following the recommendations made by the Internet Engineering Task Force (IETF).},

abstract = {The fast growth of the Internet of Things (IoT) has made this technology one of the most promising paradigms of recent years. Wireless Sensor Networks (WSNs) are one of the most important challenges of the Internet of things. These networks are made up of devices with limited processing power, memory, and energy. The constrained nature of WSNs makes it necessary to have specific restricted protocols to work in these environments. In this paper, we present an energy consumption and network traffic study of the main IoT application layer protocols, the Constrained Application Protocol (CoAP), and the version of Message Queue Telemetry Transport (MQTT) for sensor networks (MQTT_SN). The simulations presented evaluate the performance of these protocols with different network configurations.},
