论文摘要
闪电网络（LN）通过利用链交易来解决比特币的可扩展性问题。但是，由于其存储，内存和处理要求，无法在资源受限的物联网设备上运行LN。因此，在本文中，我们提出了一个有效且安全的协议，该协议使IoT设备能够通过网关LN节点使用LN的功能。这个想法是将IoT设备涉及LN操作中的数字签名，通过用3中的3个多符号通道代替原始的2个多标志性通道，以其数字签名。我们的协议强制执行LN网关，要求对频道上所有操作的IoT设备的加密签名。我们通过在Raspberry Pi上实施TOLL支付方案，并证明了其可行性和安全性，从而评估了提出的协议。
Lightning Network (LN) addresses the scalability problem of Bitcoin by leveraging off-chain transactions. Nevertheless, it is not possible to run LN on resource-constrained IoT devices due to its storage, memory, and processing requirements. Therefore, in this paper, we propose an efficient and secure protocol that enables an IoT device to use LN's functions through a gateway LN node. The idea is to involve the IoT device in LN operations with its digital signature by replacing original 2-of-2 multisignature channels with 3-of-3 multisignature channels. Our protocol enforces the LN gateway to request the IoT device's cryptographic signature for all operations on the channel. We evaluated the proposed protocol by implementing it on a Raspberry Pi for a toll payment scenario and demonstrated its feasibility and security.
