基于可验证延迟函数的IoT网络拒绝服务攻击防范

Preventing Denial of Service Attacks in IoT Networks through Verifiable Delay Functions

Vidal Attias, Luigi Vigneri, Vassil Dimitrov

摘要:

无需许可的分布式账本提供了一种很有前途的方法来处理物联网(IoT)范式。由于物联网设备主要产生数据交易和小额支付,因此使用费用来管理网络访问的分布式账本并不是最佳选择。在本文中,我们研究了IOTA开发的一种专门为物联网设计的无费用架构。由于缺乏费用,恶意节点可以利用此功能生成无限数量的事务并执行拒绝服务攻击。我们建议通过可验证的延迟函数来减轻这些攻击。这些功能,这是不可并行化,难以计算,易于验证,最近才制定。在我们的工作中,我们设计了一个拒绝服务预防机制,解决网络异构性,有限的节点计算能力,和硬件特定的实现优化。可验证延迟函数大多从理论角度进行研究,但在实际应用中做得很少。因此,本文可以被认为是该领域的开创性工作,因为它在理论数学框架和现实问题之间架起了桥梁。

英文摘要:

Permissionless distributed ledgers provide a promising approach to deal with the Internet of Things (IoT) paradigm. Since IoT devices mostly generate data transactions and micropayments, distributed ledgers that use fees to regulate the network access are not an optimal choice. In this paper, we study a feeless architecture developed by IOTA and designed specifically for the IoT. Due to the lack of fees, malicious nodes can exploit this feature to generate an unbounded number of transactions and perform a denial of service attacks. We propose to mitigate these attacks through verifiable delay functions. These functions, which are non-parallelizable, hard to compute, and easy to verify, have been formulated only recently. In our work, we design a denial of service prevention mechanism which addresses network heterogeneity, limited node computational capabilities, and hardware-specific implementation optimizations. Verifiable delay functions have mostly been studied from a theoretical point of view, but little has been done in tangible applications. Hence, this paper can be considered as a pioneer work in the field, since it builds a bridge between this theoretical mathematical framework and a real-world problem.
