Abstract

Remote attestation is used to enable verifiers to check if an underlying Trusted Computing Base (TCB) of a device and data from the TCB are trustworthy. However, the current remote attestation has limitations to be deployed in IoT from the perspective of the management in a massive and diverse collection of TCB measurements and the redundant execution of remote attestation. To mitigate these limitations, we present a trustworthy management of TCB measurements called TM-Coin (TCB Measurement-Coin) using the blockchain and ARM TrustZone. The TM-Coin transactions and protocol are presented to manage the TCB measurements of IoT devices using the blockchain, a decentralized database. The trusted execution environment provided by ARM TrustZone is used as the TCB to generate the TM-Coin transactions securely. Based on TM-Coin, the verifiers launch remote attestation of sensed data from the devices using the TCB measurements published in the blockchain without attesting to the TCB. We implemented a prototype to evaluate the performance overhead caused by TM-Coin.

TM-Coin:物联网中TCB测量的可靠管理

远程认证用于验证者检查设备的底层可信计算基础(TCB)和来自TCB的数据是否可信。然而，从管理大量不同的TCB测量集合和远程认证的冗余执行的角度来看，目前的远程认证在物联网中部署有局限性。为了减轻这些限制，我们提出了一种可信赖的TCB测量管理，称为TM-Coin (TCB Measurement-Coin)，使用区块链和ARM TrustZone。TM-Coin交易和协议用于使用区块链(一个分散的数据库)管理物联网设备的TCB测量。使用ARM TrustZone提供的可信执行环境作为TCB，安全地生成TM-Coin交易。基于TM-Coin，验证者使用区块链中发布的TCB测量值对来自设备的感测数据进行远程认证，而无需对TCB进行认证。我们实现了一个原型来评估TM-Coin带来的性能开销。
