Abstract. Nowadays, Wireless Sensors Networks (WSN) are the most important components in the booming Internet of Things (IoT). Given the use of WSN in systems that are part of the critical infrastructure of a country, the primary task is continuous authentication of WSN nodes. This paper describes how to use the Trusted Platform Module (TPM) to authenticate sensors which create a sensors' domain in WSN. A model of wireless sensor network as well as operations associated with authentication in the sensors domain are presented. Additionally, an implementation of selected operations in the sensors domain is described; this includes: the master node initialization, slave nodes registration, and data transfer between them. Testing environment including the construction of nodes equipped with the TPM is described. The solution developed by the authors of the paper is only a partial realization of a broader concept of authentication in WSNs supported by the TPM.
