        abstract = {We address the widely open problem of access control in wireless sensor networks (WSN). Namely, we apply a suitable threshold secret sharing scheme relying on advanced polynomial interpolation theory to design a distributed access control protocol exploiting the natural hierarchical structure of the WSN.}
