A Survey on Hardware Approaches for Remote Attestation in Network Infrastructures

Abstract: 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.
