论文摘要
本文介绍了一项关于分布式分类帐技术（DLTS）的安全攻击的模拟研究。我们特别关注这些系统的基础对等层的攻击，这是负责传播包含数据和交易的消息，这些消息将在所有参与者之间传播。特别是，我们考虑了SYBIL攻击，根据该攻击，恶意节点会创建许多Sybils，这些Sybil从特定的攻击节点中删除消息，甚至来自诚实节点的所有消息。我们的研究表明，选择特定的传播方案以及每个同伴具有的连接量对这种攻击的阻力有影响。
This paper describes a simulation study on security attacks over Distributed Ledger Technologies (DLTs). We specifically focus on attacks at the underlying peer-to-peer layer of these systems, that is in charge of disseminating messages containing data and transaction to be spread among all participants. In particular, we consider the Sybil attack, according to which a malicious node creates many Sybils that drop messages coming from a specific attacked node, or even all messages from honest nodes. Our study shows that the selection of the specific dissemination protocol, as well as the amount of connections each peer has, have an influence on the resistance to this attack.
