abstract = {Due to the growth in the amount and type of connected devices, mainly IoT devices, new scalable, lightweight and security-aware protocols, e.g., CoAP and MQTT, have been defined. For the definition of these protocols, the axioms concerning security must cover all the needs regarding authentication, confidentiality, integrity and availability of both devices and servers.



CoAP specifies mainly protocol security based on the transport layer through DTLS. Nevertheless, OSCORE (Object Security for Constrained RESTful Environments) has been recently defined to support end-to-end protection of RESTful interactions over the CoAP protocol. It was designed for constrained devices and networks supporting a range of proxy operations, including translation between different transport protocols. The main challenge presents in OSCORE is the establishment and exchange of pre-shared keys required to protect data. For that, this paper defines how use an optimised version of SRAM-based PUF (Physical Unclonable Functions) for a secure authentication, key establishment and exchanging model. The proposal has been implemented and evaluated in a scenario including IoT devices.},
