摘要

我们考虑物联网资源与可信执行环境(TEE)，并提出了一个模型，以提供与区块链支付相关联的可信资源访问，确保物联网数据的完整性和保密性。该模型建立在广泛使用的OAuth 2.0开放授权框架之上，该框架为物联网资源提供委托授权。我们利用哈希锁和时间锁机制，将物联网资源TEE提供的可信资源访问加密链接到授权授予和区块链支付。该模型在树莓派的OP-TEE开源端口中实现，该端口使用ARM的TrustZone，并在Rinkeby公共以太坊测试网络上进行评估。

IoT Resource Access utilizing Blockchains and Trusted Execution Environments

We consider IoT resources with a Trusted Execution Environment (TEE) and propose a model to provide trusted resource access that is linked to blockchain payments, ensuring the integrity and confidentiality of the IoT data. The model is built on the widely used OAuth 2.0 open authorization framework, which provides delegated authorization for IoT resources. We utilize hash-lock and time-lock mechanisms to cryptographically link trusted resource access, provided by the IoT resource’s TEE, to authorization grants and blockchain payments. The model is implemented in the OP-TEE open source port for the Raspberry Pi that uses ARM’s TrustZone and is evaluated on the Rinkeby public Ethereum testnet.
