Trusted platform modules (TPM) have become important safe‐guards against
variety of software‐based attacks. By providing a limited set of
cryptographic services through a well‐defined interface, separated from
the software itself, TPM can serve as a root of trust and as a building
block for higher‐level security measures. This article surveys the
literature for applications of TPM in the cloud‐computing environment,
with publication dates comprised between 2013 and 2018. It identifies
the current trends and objectives of this technology in the cloud, and
the type of threats that it mitigates. Toward the end, the main research
gaps are pinpointed and discussed. Since integrity measurement is one
of the main usages of TPM, special attention is paid to the assessment
of run time phases and software layers it is applied to.
