This work describes a practical solution for the problem of cryptographic key establishment and secure communication in the context of the Internet of Things, in which computational eciency is a fundamental requirement. A symmetric-key establishment protocol based on AES, Poly1305-AES, time synchronization, Elliptic Curve Die-Hellman and sensor IDs is proposed to achieve data condentiality, authentication, integrity and prevention from replay attacks. Such a protocol was implemented in the EPOS

Tests were executed on the EPOSMoteII platform and the analysis of the results shows that the implementation is adequate to be used in the scenario of embedded systems with low processing power.
