  Remote attestation schemes have been utilized for assuring the integrity of a
network node to a remote verifier. In recent years, a number of remote
attestation schemes have been proposed for various contexts such as cloud
computing, Internet of Things (IoTs) and critical network infrastructures.
These attestation schemes provide a different perspective in terms of security
objectives, scalability and efficiency. In this report, we focus on remote
attestation schemes that use a hardware device and cryptographic primitives to
assist with the attestation of nodes in a network infrastructure. We also point
towards the open research challenges that await the research community and
propose possible avenues of addressing these challenges.
