<div class="abstract">
|
|
<p>Available purely software based code attestation protocols
|
|
have recently been shown to be cheatable. In this work we
|
|
propose to upload compressed instruction code to make the
|
|
code attestation protocol robust against a so called com-
|
|
presssion attack. The described secure code attestation pro-
|
|
tocol makes use of recently proposed micro-controller archi-
|
|
tectures for reading out compressed instruction code. We
|
|
point out that the proposed concept only makes sense if the
|
|
provided cost/benefit ratio for the aforementioned micro-
|
|
controller is higher than an alternative hardware based so-
|
|
lution requiring a tamper-resistant hardware module.</p> </div>
