摘要:

我们提出了一种低开销的机制,用于约束网络中物联网代理的自主识别和通信。我们的主要贡献是使本地使用分散标识符(DID)和基于DID的安全通信的约束网络,而以前的作品要么没有考虑这个问题,或依赖于基于代理的架构。我们提出了一个新的扩展DID以及一个更简洁的序列化方法DID元数据。此外,为了减少传输消息的安全开销,我们采用了二进制消息信封。我们在Swarm Computing的背景下实现了这些建议,这是一种去中心化物联网的方法。结果表明,我们的提案将身份元数据的大小减少了近四倍,安全开销减少了五倍。我们观察到,这两种技术都需要在约束网络上进行操作。

英文摘要:

We present a low-overhead mechanism for self-sovereign identification and communication of IoT agents in constrained networks. Our main contribution is to enable native use of Decentralized Identifiers (DIDs) and DID-based secure communication on constrained networks, whereas previous works either did not consider the issue or relied on proxy-based architectures. We propose a new extension to DIDs along with a more concise serialization method for DID metadata. Moreover, in order to reduce the security overhead over transmitted messages, we adopted a binary message envelope. We implemented these proposals within the context of Swarm Computing, an approach for decentralized IoT. Results showed that our proposal reduces the size of identity metadata in almost four times and security overhead up to five times. We observed that both techniques are required to enable operation on constrained networks.
