Abstract

In this paper, we propose a secure code update protocol for TPM-equipped sensor nodes, which enables these nodes to prove their trustworthiness to other nodes using efficient attestation protocols. As main contribution, the protocol provides mechanisms to maintain the ability of performing efficient attestation protocols after a code update, although these protocols assume a trusted system state which never changes. We also present a proof of concept implementation on IRIS sensor nodes, which we have equipped with Atmel TPMs, and discuss the security of our protocol.
