With the growth of IoT devices connected to the internet in order to transmit and share collected data, it is required to ensure that the data transmitted was not corrupted at any point during a transmission. This can be done by avoiding data corruption and malicious attacks that bypass authentication mechanisms. For this reason, this dissertation intends to propose a new authentication protocol for IoT devices that, while maintaining data integrity, confidentiality and non-repudiation, consumes less resources than other authentication protocols for these devices. Nowadays, data transferred from IoT devices is used in many areas such as advanced industrial installations, simple medical devices or in traffic lights systems. Therefore, any attack on these devices might cause significant problems in the infrastructures that they operate, creating economic issues on the organizations or even putting at risk people that depend on such systems. Taking these considerations in account, the importance of data integrity and authentication in IoT devices has been gaining attention in the IoT security community. Con-sequently, there are plenty of available methodologies to verify data security and integrity, but most do not address properly the issues of devices with lower computational resources. There-fore, the objective of this dissertation is to define a new lightweight authentication protocol using Physical Unclonable Functions and a guide that showcases multiples technologies that can be used to implement the proposed protocol, so that such security needs of IoT are ad-dressed, warranting a proper solution based in the level of computational power of the devices available in each system.
